Failure with IDE 2.0 and MegaCoreX

cattledog · September 17, 2022, 10:52pm

I installed IDE 2.0(Windows 10) and discovered an issue with compiling/linking a sketch for the Nano Every when using MegaCoreX.

Using the example sketch "Bare Minimum" and the board selection for the ATmega 4809 and all the settings I normally uses with 1.8.19 it compiles as normal but fails when linking with an issue related to a call for cmd /C and results in the error

'C:\Users\myName' is not recognized as an internal or external command,
operable program or batch file.

If I select the Nano Every as an Arduino megaAVR board the compile and linking are successful.

All my other third party boards available with the board selection compile and link successfully.

Hi @cattledog. I'm going to ask you to post some additional information that might help us to identify the problem.

NOTE: These instructions will not solve the problem. They are only intended to possibly gather some more information about the problem, which might provide a clue that leads to a solution.

Please do this:

Select File > Preferences from the Arduino IDE menus.
Check the box next to "Show verbose output during: ☐ compilation".
Click the OK button.
Select Sketch > Verify/Compile from the Arduino IDE menus.
Wait for the compilation to fail.
You will see a "Compilation error: ..." notification at the bottom right corner of the Arduino IDE window. Click the COPY ERROR MESSAGES button on that notification.
Open a forum reply here by clicking the Reply button.
Click the </> icon on the post composer toolbar.
This will add the forum's code block markup (```) to your reply to make sure the error messages are correctly formatted.
Press Ctrl+V.
This will paste the compilation output into the code block.
Move the cursor outside of the code tags before you add any additional text to your reply.
Click the Reply button to post the output.

The short answer is the problem is related to the spaces in your Windows user name, which results in spaces in the paths in this command:

cattledog:

cmd /C "C:\\Users\\Richard Marantz\\AppData\\Local\\Arduino15\\packages\\arduino\\tools\\avr-gcc\\7.3.0-atmel3.6.1-arduino7/bin/avr-objdump" --disassemble --source --line-numbers --demangle --section=.text "C:\\Users\\Richard Marantz\\AppData\\Local\\Temp\\arduino-sketch-A39BE6A817DA50D424C5F2FBCA7A8BE4/BareMinimum.ino.elf" > "C:\\Users\\Richard Marantz\\AppData\\Local\\Temp\\arduino-sketch-A39BE6A817DA50D424C5F2FBCA7A8BE4/BareMinimum.ino_atmega4809_16000000L.lst"

The reason why it doesn't occur in Arduino IDE 1.x is because it uses the Windows "8.3" format path (notice the RICHAR~1 instead of Richard Marantz):

cattledog:

cmd /C "C:\\Users\\Richard Marantz\\AppData\\Local\\Arduino15\\packages\\arduino\\tools\\avr-gcc\\7.3.0-atmel3.6.1-arduino7/bin/avr-objdump" --disassemble --source --line-numbers --demangle --section=.text "C:\\Users\\RICHAR~1\\AppData\\Local\\Temp\\arduino_build_534053/sketch_sep17b.ino.elf" > "C:\\Users\\RICHAR~1\\AppData\\Local\\Temp\\arduino_build_534053/sketch_sep17b.ino_atmega4809_16000000L.lst"

Spaces in paths are normally handled just fine. The reason megaCoreX is different is because it uses cmd /C to run this command. That sends us into the nightmare of trying to work with the Windows command interpreter. In this application, the paths with spaces are not so easy to work with.

I identified a workaround for this problem and submitted it to the MegaCoreX repo:

github.com/MCUdude/MegaCoreX

Prevent corruption of disassembler listing command for paths w/ spaces

MegaCoreX uses a [build hook](https://arduino.github.io/arduino-cli/latest/platf…orm-specification/#pre-and-post-build-hooks-since-arduino-ide-165) to save a disassembler listing to the build folder when compiling sketches. Due to the use of a [redirection operator](https://learn.microsoft.com/en-us/previous-versions/windows/it-pro/windows-xp/bb490982(v=technet.10)) in the command, it was necessary to execute it via the Windows command interpreter by passing it as an argument to `cmd /c`. Although paths with spaces can be used without difficulty in pattern generated commands executed directly by the Arduino framework, things are more complicated when it comes to executing commands indirectly via `cmd /c`. The `cmd /c` command has an odd handling of quotes: https://learn.microsoft.com/en-us/windows-server/administration/windows-commands/cmd#remarks Under certain conditions, the first and last quotation mark of the command passed via the argument to `/c` are stripped. These conditions occur for the command generated via the platform's `recipe.hooks.objcopy.postobjcopy.1.pattern.windows` property when the both the path to `avr-objdump` and the temporary build path contain a space. The removal of the essential quotes from the start and end of the command executed by `cmd /c` causes an error. for example, if the `avr-objdump` path was: ```text C:\Users\username with spaces\AppData\Local\\Arduino15\packages\arduino\tools\avr-gcc\7.3.0-atmel3.6.1-arduino7\bin\avr-objdump ``` The command will fail with the error: ```text 'C:\Users\username' is not recognized as an internal or external command, operable program or batch file. ``` One of the required conditions for the unwanted quote stripping is that the first character of the argument to `cmd /c` is a double quote. So this unwanted behavior can be avoided by ensuring the first character is not a double quote. That is accomplished here by adding [a dummy command](https://learn.microsoft.com/en-us/windows-server/administration/windows-commands/echo#examples) (adds a blank line to the output, but the most suitable "no operation" candidate I found) that does not require quoting at the start of the argument. ## Demo of bug ```text $ ./arduino-cli version arduino-cli.exe Version: 0.27.1 Commit: a900cfb2 Date: 2022-09-18T15:57:51Z $ export ARDUINO_DIRECTORIES_DATA="/tmp/arduino-cli-directories/has space/data" # Cause avr-objdump to be installed under a path with spaces $ ./arduino-cli core install MegaCoreX:megaavr --additional-urls https://mcudude.github.io/MegaCoreX/package_MCUdude_MegaCoreX_index.json [...] $ ./arduino-cli sketch new "/tmp/FooSketch" Sketch created in: C:\Users\per\AppData\Local\Temp\FooSketch $ ./arduino-cli compile --fqbn MegaCoreX:megaavr:4809 --verbose --build-path "/tmp/arduino-cli-directories/has space/build" "/tmp/FooSketch" [...] cmd /C "C:\\Users\\per\\AppData\\Local\\Temp\\arduino-cli-directories\\has space\\data\\packages\\arduino\\tools\\avr-gcc\\7.3.0-atmel3.6.1-arduino7/bin/avr-objdump" --disassemble --source --line-numbers --demangle --section=.text "C:\\Users\\per\\AppData\\Local\\Temp\\arduino-cli-directories\\has space\\build/FooSketch.ino.elf" > "C:\\Users\\per\\AppData\\Local\\Temp\\arduino-cli-directories\\has space\\build/FooSketch.ino_atmega4809_16000000L.lst" 'C:\Users\per\AppData\Local\Temp\arduino-cli-directories\has' is not recognized as an internal or external command, operable program or batch file. [...] ``` ## Additional information ### Alternatives considered It might seem that a less hacky approach would be to simply wrap the entire argument to `cmd /c` in an extra layer of sacrificial quotes, leaving the essential quotes intact in the command that is finally executed. While that does indeed work when running the command directly from the command line, it does not work when used in a pattern in the Arduino platform configuration framework. The problem is that the string generated from the platform pattern can not be executed as is. It must be [split into arguments](https://github.com/arduino/go-properties-orderedmap/blob/v1.6.0/strings.go#L38). The list of arguments space separated, with quoting where an argument contains a space. These arguments may contain quote characters, which must be escaped. This escaping is where the simple approach of extra quotes becomes unusable. [The `os/exec` Go package](https://pkg.go.dev/os/exec) used to handle the escaping does that in a way that is compatible with directly executing a command, but is not compatible with the legacy escaping system used by cmd: <https://pkg.go.dev/os/exec#Command> >On Windows, processes receive the whole command line as a single string and do their own parsing. Command combines and quotes Args into a command line string with an algorithm compatible with applications using CommandLineToArgvW (which is the most common way). Notable exceptions are msiexec.exe and cmd.exe (and thus, all batch files), which have a different unquoting algorithm. In these or other similar cases, you can do the quoting yourself and provide the full command line in SysProcAttr.CmdLine, leaving Args empty. ### Scope of bug It seems this problem of the command having paths with spaces did not occur in Arduino IDE 1.x due to it using a [Windows "8.3" format](https://en.wikipedia.org/wiki/8.3_filename) for the default build path, which does not contain spaces. [Arduino CLI](https://arduino.github.io/arduino-cli/latest/) (and thus [Arduino IDE 2.x](https://github.com/arduino/arduino-ide)) uses the full path format instead. However, the bug could also occur in Arduino IDE 1.x if the user sets a custom `build.path` with spaces. `recipe.hooks.savehex.presavehex.2.pattern.windows` also uses `cmd /C`. However, this command is not subject to the quote stripping because it does not ever have a double quote as the first character of the argument. ### Related Originally reported at https://forum.arduino.cc/t/failure-with-ide-2-0-and-megacorex/1032918

There are more details about the problem at the link above.

Applying the fix manually

If accepted, the problem should no longer occur once the next release of MegaCoreX comes out. However, you might prefer to apply the fix manually right now so that you don't have to wait.

You can see the small change that needs to be made here:

https://github.com/MCUdude/MegaCoreX/pull/159/files

But I'll provide instructions:

Open the file at this path in any text editor:

C:\Users\Richard Marantz\AppData\Local\Arduino15\packages\MegaCoreX\hardware\megaavr\1.1.0\platform.txt

Change line 78 from this:

recipe.hooks.objcopy.postobjcopy.1.pattern.windows=cmd /C "{compiler.path}{compiler.objdump.cmd}" {compiler.objdump.flags} "{build.path}/{build.project_name}.elf" > "{build.path}/{build.project_name}_{build.mcu}_{build.f_cpu}.lst"

to this:

recipe.hooks.objcopy.postobjcopy.1.pattern.windows=cmd /C echo. && "{compiler.path}{compiler.objdump.cmd}" {compiler.objdump.flags} "{build.path}/{build.project_name}.elf" > "{build.path}/{build.project_name}_{build.mcu}_{build.f_cpu}.lst"

Save the file.
If the Arduino IDE is running, select File > Quit from the Arduino IDE menus.
Start the Arduino IDE.
ⓘ It is necessary to restart the Arduino IDE in order to make it recognize the change you made to platform.txt.

Now try compiling a sketch using the MegaCoreX board selection. Hopefully the error will no longer occur.

Please let me know if you have any questions or problems while following those instructions. Please also let me know how it works for you.

cattledog · September 18, 2022, 5:07pm

No problems, and solution worked as expected. Thank you very much for your help with this issue. The pull request information is very complete.

Are there any other cores with this issue?

ptillisch · September 18, 2022, 6:27pm

You are welcome. I'm glad it is working.

Yeah:

I figured I would start with MegaCoreX. Once that PR has been reviewed and approved it should be fairly easy to apply the same fix to the others as well.

cattledog · September 19, 2022, 4:24am

I think I was to quick to mark this thread solved.
When I moved beyond the compile issue to actually upload, there are new errors.
As before, there are no issues with 1.8.19

Again with the bare minimum sketch it appears there are issues with avrdude and the configuration file. Perhaps because of a path name with a space in the user name?

ptillisch · September 19, 2022, 5:24am

The problem is here that a different version of AVRDUDE was used than the one MegaCoreX is configured to be used with:

C:\Users\Richard Marantz\AppData\Local\Arduino15\packages\arduino\tools\avrdude\6.3.0-arduino17/bin/avrdude

The one that should be used is here:

C:\Users\Richard Marantz\AppData\Local\Arduino15\packages\MegaCoreX\tools\avrdude\7.0.0-arduino2/bin/avrdude

There are a couple of ways the Arduino framework can be configured to use a specific tool:

Specifying the version by using the property format {runtime.tools.TOOL_NAME-TOOL_VERSION.path}
Specifying the vendor and version via the toolsDependencies field of the package index.

MegaCoreX does not do the former:

https://github.com/MCUdude/MegaCoreX/blob/v1.1.0/megaavr/platform.txt#L115

tools.avrdude.path={runtime.tools.avrdude.path}

This leaves the IDE to pick any tool named avrdude that is present.

However, it does specify the correct version in the package index:

https://mcudude.github.io/MegaCoreX/package_MCUdude_MegaCoreX_index.json

"toolsDependencies": [
  {
    "packager": "arduino",
    "name": "avr-gcc",
    "version": "7.3.0-atmel3.6.1-arduino7"
  },
  {
    "packager": "MegaCoreX",
    "name": "avrdude",
    "version": "7.0.0-arduino2"
  },

So why isn't that information being used? I suspect it is because you don't have the package index URL in your preferences. Arduino IDE 2.x uses a different preferences store from Arduino IDE 1.x, so it is necessary to manually migrate the URLs to the "Additional Boards Manager URLs" field.

Select File > Preferences from the Arduino IDE menus.
Enter the following URL into the "Additional Boards Manager URLs" field:
```
https://mcudude.github.io/MegaCoreX/package_MCUdude_MegaCoreX_index.json
```
If there are already Boards Manager URLs in the field, separate them with commas.
Click the OK button.
You will now see a "Downloading index: ..." notification at the bottom right corner of the IDE window. Wait for that notification to close.

Now try uploading again. Hopefully the right AVRDUDE will be selected.

I just gave it a try and was not able to reproduce the issue. It does seem like it is a problem with missing dependencies (e.g., a DLL or something) in the Windows environment.

If you want to try an experiment, Arduino has produced a tester build of AVRDUDE 7.0. Arduino's build configuration is specifically designed to avoid this sort of external dependency.

The tester build download links are listed under the "Assets" section of this page:

For windows, use the "avrdude_7.0-arduino.3_Windows_32bit.tar.gz" link.

After extracting the downloaded file, take the file avrdude_Windows_32bit\bin\avrdude.exe from the extracted folder and use it to replace the one at this path:

C:\Users\Richard Marantz\AppData\Local\Arduino15\packages\MegaCoreX\tools\avrdude\7.0.0-arduino2/bin/avrdude.exe

You can rename the original file from that path to something like avrdude.exe.original in order to make it easy to later revert the replacement if you decide to do so.

I replaced the original averdude with the alternative.
I used WinZip to decompress and extract the file.
It has a different created date ‎Tuesday, ‎June ‎21, ‎2022, ‏‎12:40:26 AM
than the original ‎Saturday, ‎July ‎9, ‎2022, ‏‎10:58:28 PM so I think I managed the download and extraction correctly. The forum software won't let me attach the extracted file for you to verify.

If the issue is a missing DLL, why does 1.8.19 work properly. What is the dependency of 2.0 on what DLL?

ptillisch · September 19, 2022, 11:06pm

Good question.

My assumption was that it is AVRDUDE that has the dependency, not Arduino IDE. The error messages that come from the process is expected to be from AVRDUDE.

Please try this:

Attempt an upload in Arduino IDE.
Wait for the upload to fail.

Copy the avrdude command line the Arduino IDE generated.
For example, in your output above, the command was:

"C:\Users\Richard Marantz\AppData\Local\Arduino15\packages\MegaCoreX\tools\avrdude\7.0.0-arduino2/bin/avrdude" "-CC:\Users\Richard Marantz\AppData\Local\Arduino15\packages\MegaCoreX\hardware\megaavr\1.1.0/avrdude.conf" -v -V -patmega4809 -cjtag2updi -PCOM3 -e "-Uflash:w:C:\Users\Richard Marantz\AppData\Local\Temp\arduino-sketch-D0236B91031AFCFCDB041F1806E86B6D/BareMinimum.ino.hex:i" "-Ufuse0:w:0x00:m" "-Ufuse1:w:0x54:m" "-Ufuse2:w:0x02:m" "-Ufuse4:w:0x00:m" "-Ufuse5:w:0b11001001:m" "-Ufuse6:w:0x06:m" "-Ufuse7:w:0x00:m" "-Ufuse8:w:0x00:m" "-Ulock:w:0xC5:m"

(but make sure to use the one freshly generated in the IDE so you can make sure the files in the temporary build folder still exist)

Run that command from the command line.

Upload to the Nano Every board requires a "1200-bps touch", which is done by Arduino IDE/Arduino CLI separately from AVRDUDE (AVRDUDE doesn't have this capability), so the upload is expected to fail when you run it from the command line. But it should fail in a different way than what you are seeing in the Arduino IDE, at a stage farther along in the upload process from the point where you are getting this mysterious error. So even without the "1200-bps touch", this should still serve the purposes of effectively eliminating the Arduino IDE and Arduino CLI from the equation.

Brilliant suggestion.

I got an error about a missing file libusb0.dll.

What next?

cattledog · September 20, 2022, 12:45am

The libus0.dll file appears to be included at several places
In 1.8.19 is see it in Arduino>hardware>tools>avr>bin
In Programs x86 I also see it at a top level.

I do not see it in the file with Arduino 2.0.
C:\Users\Richard Marantz\AppData\Local\Programs\Arduino IDE

ptillisch · September 20, 2022, 12:45am

I see this is a known issue with Arduino's tester build of AVRDUDE 7.0 (Arduino does not yet use this version of AVRDUDE in any of the boards platforms):

libusb0.dll missing

type: imperfection type: enhancement os: windows conclusion: resolved topic: code

## libusb0.dll missing At Embeetle IDE, we provide one of your Windows releas…es on our download server. One of our users experienced the following error on Windows 10 when trying to run the executable: ![image](https://user-images.githubusercontent.com/19362684/182669317-448a5e07-44b2-4035-8788-d1ae12263357.png) The error message reads: > avrdude.exe - System Error > The code execution cannot proceed because `libusb0.dll` was not found. Reinstalling the program may fix this problem.   ## AVRDUDE version The user downloaded the following AVRDUDE version: https://new.embeetle/downloads/beetle_tools/windows/avrdude_7.0.0_32b.7z It's basically one of your `7.0` releases. I don't remember if it's `7.0-arduino.1`, `7.0-arduino.2-rc1` or `7.0-arduino.2` (it certainly isn't `7.0-arduino.3` yet). When I run the executable on my PC, I only get this version output: ``` avrdude version 7.0, URL: <https://github.com/avrdudes/avrdude> ``` So I know it's version `7.0` - but not more specific. ## Notes - Didn't you link the `libusb` library statically? Why is AVRDUDE looking around for the `dll`? - I sent your latest `7.0-arduino.3` release to the user experiencing the above mentioned problem. He just ran a test and the problem is still there.

As for the question of why this error does not occur when using Arduino IDE 1.x, I see now that the Arduino IDE 1.x installation includes the file libusb0.dll in the root of the installation folder, so maybe it is able to pick it up there?

I also see that Arduino's production releases of AVRDUDE contain a copy of libusb0.dll in the same folder as avrdude.exe.

So I see two possible fixes:

Add the missing DLL

Copy the file at this path:

C:\Users\Richard Marantz\AppData\Local\Arduino15\packages\arduino\tools\avrdude\6.3.0-arduino17\bin

To this folder:

"C:\Users\Richard Marantz\AppData\Local\Arduino15\packages\MegaCoreX\tools\avrdude\7.0.0-arduino2\bin

Try the official AVRDUDE build

After further investigation, I see that MCUdude is distributing Arduino's build of AVDUDE with MegaCoreX (though it is an older release 7.0-arduino.2). So you actually might find that the official AVRDUDE build does not have this DLL dependency.

You can download it from the link on the "Assets" section of this page:

Use the "avrdude-v7.0-windows-x64.zip" download link

Arduino IDE 1.x installation includes the file libusb0.dll in the root of the installation folder, so maybe it is able to pick it up there?

I added libusb0.dll to 2.0 IDE program file at the top level of the installation folder like it is in 1.8.19.

C:\Users\Richard Marantz\AppData\Local\Programs\Arduino IDE

The upload to the Nano Every with MegaCoreX was successful.

I suggest that you include libusb0 in the installation folder of IDE as was previously done.

I have left the Averdude 7.0 which I installed following post #16. Should I leave it or replace it with the original. Both the original and the file I exchanged have the same number of bytes. Are they indeed different?

Thank you for all your assistance. The use of the command line to find the missing .dll was the key.

Without your continued support I would have abandoned using 2.0 until there were a few more releases. I hope my adventure will help others.

We are trying to keep the IDE installation dedicated as much as possible to the application itself, as a general purpose tool for Arduino sketch development.

Arduino IDE 1.x was developed in a time when all boards were AVR, which resulted in the approach where the AVR boards platform, toolchain, drivers, and dependencies were bundled with the IDE installation. But this approach does not scale and also does not accommodate 3rd party boards.

So I would try to avoid adding a file that is a dependency of board-specific tools to the IDE installation. I think the better approach would be to include it with the AVRDUDE installation, or even better to avoid the dependency altogether if possible.

My advice is to stay as close as possible to a vanilla MegaCoreX installation. So if the original works just as well for you as the replacement then I recommend switching back to using the original. The replacement was intended more as an experiment while I was in the "grasping at straws" stage of the investigation.

Not in this application. The difference between the 7.0-arduino.2 version installed with MegaCoreX and the latest 7.0-arduino.3 version is a fix for a bug in an ATtiny85-specific patch applied to Arduino's avrdude.conf configuration file:

github.com/arduino/avrdude-packing

Correct patch for ATtiny85 erase and flash delay config adjustments

arduino:main ← per1234:fix-attiny85-patch

opened 12:44AM - 21 Jun 22 UTC

per1234

+13 -13

The previous version of the patch had been incorrectly ported to AVRDUDE 7.0, re…sulting in some of the changes being applied to the ATtiny2313 and AT90PWM2 parts instead of ATtiny85 as intended. Reference: https://github.com/arduino/avrdude-build-script/blob/master/avrdude-6.3-patches/60-avrdude-6.3-attiny85_delay_increase.patch

But MegaCoreX does not even use that file you find under the etc folder of the AVRDUDE download. It uses this one instead:

https://github.com/MCUdude/MegaCoreX/blob/master/megaavr/avrdude.conf

There were no changes to the AVRDUDE source code between 7.0-arduino.2 and 7.0-arduino.3

You are welcome.

Thanks also for your feedback. MegaCoreX and the other MCUdude boards platforms are very important parts of the Arduino ecosystem. The Arduino Tooling team does try to give attention to ensuring the tools we create and maintain are compatible with the 3rd party boards platforms in addition to Arduino's official platforms.
