Can program SAMD5x on Windows, but not macOS

[jetforme]

I got a Teknic ClearCore motion controller that's based on an Atmel SAME5 MCU, and they have Arduino support for programming it. I'm able to build the examples on macOS using Arduino 2.x, but programming the chip (using bossac) fails to verify. It does seem to write something, but it always fails to verify. Doing the same with Arduino on Windows works fine.

I emailed them over the weekend with a detailed message, but they just came back saying they don't support macOS.

Unfortunately, while Arduino on macOS shows the bossac invocation, it doesn't show the invocation or programming parameters on Windows.

I'm wondering if there’s something wrong with the way the macOS setup is invoking bossac:

"/Users/rmann/Library/Arduino15/packages/arduino/tools/bossac/1.9.1-arduino1/bossac" -i -d -a --port=cu.usbmodem3224101 -U -e -w -v --offset=0x4000 "/Users/rmann/Library/Caches/arduino/sketches/71F55F8C0907EEFE4D496BFF118C38F3/AsgWithMeasuredTorque.ino.bin" -R

The device seems to have a UF2 bootloader on it. When you connect it, a drive mounts with CURRENT.UF2 and INFO_UF2.TXT which contains

UF2 Bootloader v2.3.1-Teknic.4 SLFHRO
Model: ClearCore
Board-ID: SAME53N19A-ClearCore-F1

Is there any way to get the details of how the Windows programmer is invoked? Any other ideas to try?

Hi @jetforme.

@jetforme

Unfortunately, while Arduino on macOS shows the bossac invocation, it doesn't show the invocation or programming parameters on Windows.

You probably have the Show verbose output during: ☐ upload option enabled in the Arduino IDE preferences on your macOS machine, but disabled on the Windows machine.

@jetforme

Is there any way to get the details of how the Windows programmer is invoked?

Yes, I'll provide instructions:

1. Select File > Preferences... (or Arduino IDE > Settings... for macOS users) from the Arduino IDE menus.
   The "Preferences" dialog will open.
2. Uncheck the box next to Show verbose output during: ☑ compile in the "Preferences" dialog.
   ⓘ This is not absolutely necessary, but the compilation output is likely not relevant to this effort so it will be best to exclude the superfluous verbose compilation output so that you can focus on the verbose upload output.
3. Check the box next to Show verbose output during: ☐ upload.
4. Click the "OK" button.
   The "Preferences" dialog will close.
5. Perform an upload, just as you did before.

Now you can carefully compare the output produced by that upload against the output from an upload on the macOS machine. If you like, you can post both outputs in a reply here on the forum thread and the forum helpers will take a look.

Okay, the invocations are identical, as are the outputs up until the read/verify stage. The macOS version also has an additional output line for each progress update.

The output for the same source code compiled on each platform:

macOS output:

Okay I found a solution. This BOSSA PR fixes the issue, although it’s out of date. I added tcflush to the flush routine on the main branch (and left the delay in), and it now seems to program reliably. It’s not clear to me why it fails so miserably (instead of just failing to write the last few bytes), but it seems to work.

Unfortunately, that PR has been sitting there for nearly four years (and the last commit to main was four years ago), so I don't know if BOSSA is getting any more maintenance.

[ptillisch]

Nice work finding a solution @jetforme. Thanks for taking the time to post an update with your findings!

Arduino maintains a fork of BOSSA. I see that Arduino made a modification to the same code that was changed in the upstream PR you found:

try again on EAGAIN errors and flush

I believe that change was made after the time of the "1.9.1-arduino1" version of bossac you were using (I can't be certain because, frustratingly, the developers didn't push a 1.9.1-arduino1 tag to the repository so who knows what the heck is in that "1.9.1-arduino1" version). If you would like to give it a try, the download links for the binaries are listed here:

Release Binaries for 1.9.1-arduino2 (nRF support) · arduino/BOSSA

[jetforme]

@ptillisch

If you would like to give it a try, the download links for the binaries are listed here:

Release Binaries for 1.9.1-arduino2 (nRF support) · arduino/BOSSA · GitHub

Whoa. I already have a 1.9.1-arduino2 in the tools directory, but the IDE isn't choosing it. I'm not sure how the tool gets selected.

[ptillisch]

@jetforme

I'm not sure how the tool gets selected.

The developers of the "ClearCore" boards platform specified that version should be used when uploading to boards of that platform:

Teknic-Inc/ClearCore-Arduino-wrapper/blob/6fa1d810705c518b78962cb2a7bd7326bddf9d08/package_clearcore_index.json#L122-L126

Reference:

https://arduino.github.io/arduino-cli/latest/package_index_json-specification/#how-a-tools-path-is-determined-in-platformtxt

[jetforme]

Okay, so I just modified my tools installation in place to refer to -arduino2, which didn’t work. I check the sources for the -arduino2 release, and it implements flush like this:

void
PosixSerialPort::flush()
{
    fsync(_devfd);
}

I used tcdrain(). I cloned the Arduino BOSSA repo, checked out 1.9.1-arduino2, and modified flush:

void
PosixSerialPort::flush()
{
    tcdrain(_devfd);
}

This works. So, Arduino needs to change this, I think, no? Is there a formal bug I should submit? I'm not sure where.

[ptillisch]

Unfortunately the issue tracker isn't enabled on the arduino/BOSSA repository (GitHub disables the issue tracker by default on forks), so there isn't any way to submit a bug report to Arduino's fork. You are welcome to submit a pull requests, but I see now that someone already submitted one:

Fix MacOS write error caused by unflushed buffer

You can use GitHub's "Reactions" feature to add a to the pull request message to express support for the proposal.

[jetforme]

Wow, that's been there for over three years. What does it take to get something this trivial merged?

[rolfg1]

Hi,

on my machine, a bossac version 1.8-66-g52e0a4a got installed.
Exchanging that with the current 1.9.1 resolved the problem.

[jetforme]

1.9.1 does not work for me without modification. The flush call is insufficient. There's a PR for it, but it seems the repo is no longer maintained.
