Error flashing board from web editor

Software Web Editor
1

Hi; when uploading the "blink" sketch to an Arduino MKR WiFi 1010, I got the following error:
"Executing commend: exec: not started"
Compilation went fine, I guess; but last command issued to my Windows 10 machine gives an error due to the fact -I think- that the folder name isn't escaped: note the "C:/Users/Alessandro LastName/AppData/..." at te beginning of the path, compared to "C:/Users/ALESSA~1/AppData/..." in the last part.

Moreover, even if I try to execute the command within a shell, another error occurs given that the path does not exists: in fact under C:/Users/ALESSA~1/.arduino-create/arduino/bossac/ I found the "1.7.0" folder (the correct one) and the "1.7.0-arduino3" file (which causes the path mess in the issued command).

Summarising: if I translate the issued command
C:/Users/Alessandro LastName/.arduino-create/arduino/bossac/1.7.0-arduino3/bossac.exe -i -d --port=COM14 -U true -i -e -w -v C:/Users/ALESSA~1/AppData/Local/Temp/arduino-create-agent897223482/Blink_copy.bin -R

to

C:/Users/ALESSA~1/.arduino-create/arduino/bossac/1.7.0/bossac.exe -i -d --port=COM14 -U true -i -e -w -v C:/Users/ALESSA~1/AppData/Local/Temp/arduino-create-agent742443738/Blink_copy.bin -R

the compiled sketch is loaded.
Many thanks in advance,
Alessandro.

It's not clear what you mean by this. Are you saying that C:/Users/ALESSA~1/.arduino-create/arduino/bossac/1.7.0-arduino3 is a file, not a folder? If so, does the filename have an extension? By default, Windows hides known filename extensions and you have to turn that off by checking the checkbox next to Windows Explorer's View > File name extensions option.

I don't think that is the full LOG either as there is usually more to it.
Do you have "Console: Show verbose output" enabled / ticked ?

Hi pert, that path corresponds to a regular file without extension: I obtained the file list after moving there by means of a "command prompt" window. It is an executable, to be precise (the cygwin 'file' utility says: "PE32 executable (console) Intel 80386, for MS Windows".)

To be honest, I don't really know why that file appeared there, and at the same time I don't know why the Create editor issued such a command. But I moved elsewhere the file, I requested another compilation/upload and it worked: more details in the next post.

Hi Bob, I enabled the verbose flag and that is the output I obtained. I attached the full file, but this is the row that gives the error:

...
Touching port COM6 at 1200bps

Set DTR off

Flashing with command:C:/Users/Alessandro LastName/.arduino-create/arduino/bossac/1.7.0-arduino3/bossac.exe -i -d --port=COM7 -U true -i -e -w -v C:/Users/ALESSA~1/AppData/Local/Temp/arduino-create-agent523151234/Blink_copy.bin -R
... command ends with error

While I was answering to pert, I made another test, after moving elsewhere the file "1.7.0-arduino3" (which is in fact the "bossac.exe" itself); the command went fine and that's the output:

...
Touching port COM7 at 1200bps

Set DTR off

Flashing with command:C:/Users/Alessandro LastName/.arduino-create/arduino/bossac/1.7.0-arduino3/bossac.exe -i -d --port=COM7 -U true -i -e -w -v C:/Users/ALESSA~1/AppData/Local/Temp/arduino-create-agent897235460/Blink_copy.bin -R

Set binary mode

... command continues successfully

The command issued is in fact the same, but as far as I understand, the first time the presence of the file "1.7.0-arduino3" caused the error; the second time, all went fine, given that in the meanwhile a folder "1.7.0-arduino3" was created and the file "bossac.exe" copied there. I don't know what the full process is: is it the agent that creates the folder structure?

As a final note, I was wrong, when I said that the unescaped path "C:/Users/Alessandro LastName/..." was a problem. Even if the same path is used in the second case, that one was successful.

Is there any plausible cause of the presence of the wrong "1.7.0-arduino3" file, or it is all attributable to some failed experiment of mine?
Many thanks,
Alessandro.

In the "PRE TEXT" you have it picking up COM 6 after the touch and then COM 7 yet in you OP the port is 14 ?

I know MKR's can and will jump ports from the regular port to the bootloader port during programming but that seems a little off.
Have you at any time reset or changed the COM ports yourself in any way ?

It may be nothing to do with your current issue that Per is the master of :slight_smile:

None of us know what experiments you might have done so it would not make much sense for me to comment on that aspect.
Any additional details as to your experiments may be useful.

Bob.

My experiments confirm that there is no problem with the upload command when there are spaces in the path. If you look at the upload recipe:

tools.bossac.upload.pattern="{path}/{cmd}" {upload.verbose} --port={serial.port.file} -U {upload.native_usb} -i -e -w -v "{build.path}/{build.project_name}.bin" -R

You can see they actually do quote the path. I don't know why it's not shown quoted in the console output.

I have no explanation for it. It's possible that Arduino Web Editor first puts a compressed file in C:/Users/Alessandro LastName/.arduino-create/arduino/bossac and then extracts it to a folder, but if that were the case I'd expect it to have a file extension like .zip or .tar.gz. If you still have the file on your computer or recycle bin, could you check the file size and post it here? You can get the file size by right clicking on the file and then clicking "Properties". The one I want is listed as "Size", not the "Size on disk".

Hi Bob, you're right, I didn't notice the "port shift".
I did not perform any operation to force a port change. I certainly did the tests in different days and moments, and I connected the board to different ports.

The experiments I did ... Unfortunately I didn't act in a rational way and I didn't keep track of the attempts: I just remember that I experienced problems even in the modeling phase of the device ("Ardino Create" and then "Device Manager") and at that point, yes, maybe I submitted in a shell some commands found on the net by hand.
I'm sorry I didn't help; I believe however that in the end the problem does not exist and that it can be traced back to a "poorly cleaned" environment on my PC.
In fact I posted the problems encountered when working under Windows, but I did not highlight that - with the same board and the same PC booted with Linux Mint - the whole procedure worked perfectly.

Many thanks,
Alessandro.

Hi Pert, thanks for the explanation and the link to github.

You're right, the path with spaces is escaped, so it gives no problem.

The fault was due to the presence of the file under "C:/Users/Alessandro LastName/.arduino-create/arduino/bossac" but I don't know how to give you more information because in the meantime I have cleaned up my PC.

As I said to Bob, above, it was probably a "dirty" file that I downloaded by hand doing some experiments after some failure during the modeling phase of a device through the "Device manager".

Now I can't say what the file in the directory was like; I do not exclude that it is the same as the one found in the "... / 1.7.0" folder (judging by the dates, they are probably the result of tests I carried out in the same days); here there is a recursive listing obtained in a cygwin shell:

Many thanks for your help!

I'm just glad to hear that you are able to upload to your Arduino now!

From the information you provided, I don't think it's necessary to investigate the problem further. I'll keep it in mind in case other users report the same problem, at which time an investigation would be warranted to make sure it's not caused by a problem in the Arduino Create plugin.

I agree.
Many thanks for the support,

Edit:
P.S. I searched back in my browser history and I found a page I've visited the day the indicted file and folder were created: Executing command: exec: not started - Web Editor - Arduino Forum
I cannot remember, but I think I've manually launched the "downloadtool avrdude ..." command, so I've messed up the plugin work directory. So, my fault...
