[SOLVED] Feather M4 Can Upload Issues

drbeeps · May 13, 2021, 2:49am

Hello Everyone,

I have recently attempted to use the Feather M4 Can from Adafruit to replace a Teensy microcontroller on one of my projects. Before I designed a board around it I bought a breakout and began testing it at home. I started by using arduino ide to test various things, spi flash, neopixel and others. When I tried to move over to platformio I was unable to make it past the upload command. Here is the output of platformio when I try to upload:

and it just hangs like that for around a minute before displaying this:

No device found on COM5
*** [upload] Error 1

I have gone through a similar thread about the same issue and was unable to fix the problem.

Here is the verbose output:

After lots of research I’m trying to do it with a custom upload command, this is the command that the arduino ide uses to upload the bin file, so I replaced the arduino bin with the bin created by platformio this is the platformio.ini:

platformio.ini:

[env:adafruit_feather_m4_can]
platform = atmelsam
board = adafruit_feather_m4_can
framework = arduino
upload_protocol = custom
upload_command = "C:\Users\Bowen Everitt\AppData\Local\Arduino15\packages\arduino\tools\bossac\1.8.0-48-gb176eee/bossac -i -d --port=COM5 -U -i --offset=0x4000 -w -v C:\dev\software-testing\more-tests\.pio\build\adafruit_feather_m4_can/firmware.bin -R"

and this is the error I get:

The filename, directory name, or volume label syntax is incorrect.

I feel like I am getting close now.

maxgerhardt · May 13, 2021, 9:11am

Mhm I don’t think you can enclose the entire command in quotes like that. Try to do it per docs, e.g.

upload_protocol = custom
upload_flags = 
   -i
   -d
   -U
   --offset=0x4000
   -w
   -v
   -R
upload_command = "C:\Users\Bowen Everitt\AppData\Local\Arduino15\packages\arduino\tools\bossac\1.8.0-48-gb176eee/bossac" $UPLOAD_FLAGS --port=$UPLOAD_PORT $SOURCE

However I’d first advise other things: Update everything. That is, open a CLI and execute pio upgrade --dev and pio platform update atmelsam to get the latest core & platform. Then retry.

If it still does not work, try replacing PlatformIO’s bossac library with what Arduino uses. PlatformIO one’s is at C:\Users\<user>\.platformio\packages\tool-bossac.

If that still does not work, it must be due to the given bossac flags, but they look very equivalent…

drbeeps · May 13, 2021, 3:51pm

I tried all of those things, none of them worked for various reasons, the one I’m trying to focus on right now is replacing the platformio bossac with the arduino bossac, I did this and I get a new error

So during the platformio upload procecss the command is made:

bossac --info --debug --port “COM5” --write --verify --reset --erase -U true .pio\build\adafruit_feather_m4_can\firmware.bin
bossac: extra arguments found
Try ‘bossac -h’ or ‘bossac --help’ for more information
*** [upload] Error 1

and thats the error I get. I have no idea why or how I can fix it.

drbeeps · May 13, 2021, 5:07pm

Alright to anyone following, I fixed the issue. I added this to the platformio.ini and put the board into bootloader mode (by pressing the reset button twice) then hitting upload

upload_protocol = custom

upload_command = “C:\Users\Bowen Everitt\AppData\Local\Arduino15\packages\arduino\tools\bossac\1.8.0-48-gb176eee/bossac” -i -d --port=COM5 -U -i --offset=0x4000 -w -v C:\dev\software-testing\more-tests.pio\build\adafruit_feather_m4_can\firmware.bin -R

Thanks maxgerhardt for the help.

maxgerhardt · May 13, 2021, 5:58pm

Does this also work with no modified upload_protocol and PlatformIO’s default bossac?

drbeeps · May 13, 2021, 6:53pm

Nope it only works with the modified platformio.ini, replacing platformios bossac with the arduino bossac did not work. So its just stock platformio stuff with the custom upload bit in the .ini file.

maxgerhardt · May 13, 2021, 6:55pm

Maybe the developers at Issues · platformio/platform-atmelsam · GitHub can help you debug this further on why it doesn’t work with PlatformIO by default, this would be very interesting for us.

pauljeff · May 19, 2021, 7:45am

Hi @drbeeps and @maxgerhardt,
For what it’s worth I thought I would test this out as I have a couple of Adafruit Feather M4 CAN’s and a couple of Adafruit Feather M4 Express’.
I created a new project in PIO, did not make any changes to platformio.ini and these are the results.
Feather M4 Express - worked fine.
Feather M4 CAN - it failed just like yours @drbeeps

Here is the last of the PIO terminal for the failure

Not sure if that helps you narrow down the problem?
I’m happy to do some more testing if you tell me what you need

pauljeff · May 19, 2021, 7:49am

Oh and I checked, the M4 CAN was definitely on /dev/cu.usbmodem14401
and the Arduino IDE programmed it on that port correctly.
Cheers.

maxgerhardt · May 19, 2021, 10:35am

Does it also work for you with the CAN board if you add a manual upload_command pointing to your Arduino IDE’s bossac tool?

pauljeff · May 20, 2021, 8:21am

Hi,
Yes that worked when I added the new lines to my platformio.ini so it now looks like

[env:adafruit_feather_m4_can]
platform = atmelsam
board = adafruit_feather_m4_can
framework = arduino
upload_protocol = custom
upload_command = /Users/ladmin/Library/Arduino15/packages/arduino/tools/bossac/1.8.0-48-gb176eee/bossac -i -d --port=/dev/cu.usbmodem14401 -U -i --offset=0x4000 -w -v "/Users/ladmin/Dropbox/Electronics/Arduino/PJ PlatformIO Projects/M4 CAN test/.pio/build/adafruit_feather_m4_can/firmware.bin" -R

here is the output

I’m on a Mac obviously

Since I don’t see that the original poster or anyone has opened an issue yet, I’ve opened one at Upload to Adafruit Feather M4 CAN board does not work · Issue #160 · platformio/platform-atmelsam · GitHub. Please participate in there if the PlatformIO have further questions / request for tests, that would be great for PlatformIO.

pauljeff · May 20, 2021, 10:41am

Thanks @maxgerhardt , will do cheers.

valeros · May 20, 2021, 3:19pm

Hi guys, thanks for reporting. Should be fixed in the dev branch. Please retest your projects with the upstream version of the atmelsam platform:

[env:adafruit_feather_m4_can]
platform = https://github.com/platformio/platform-atmelsam.git
board = adafruit_feather_m4_can
framework = arduino

pauljeff · July 25, 2021, 7:15am

Hi, I finally got my project ready to use these CAN boards and the issue still seems to be in PlatformIO, such that I have to customise my platformio.ini with the same two additional lines we were all discussing earlier in the thread. i.e.

[env:adafruit_feather_m4_can]

platform = atmelsam

;platform = https://github.com/platformio/platform-atmelsam.git

board = adafruit_feather_m4_can

framework = arduino

lib_deps =

adafruit/Adafruit HX8357 Library@^1.1.11

adafruit/Adafruit GFX Library@^1.10.10

upload_protocol = custom

upload_command = /Users/ladmin/Library/Arduino15/packages/arduino/tools/bossac/1.8.0-48-gb176eee/bossac -i -d --port=/dev/cu.usbmodem14201 -U -i --offset=0x4000 -w -v "/Users/ladmin/Dropbox/Electronics/Arduino/PJ PlatformIO Projects/Pulsar M4 CAN remote display/.pio/build/adafruit_feather_m4_can/firmware.bin" -R

I have also executed
pio upgrade --dev and pio platform update atmelsam

as suggested by @maxgerhardt to ensure my system is up to date.

I’m not sure if its something I am doing or not doing, I’m not a gun on PlatformIO.
Thanks again,
Paul

maxgerhardt · July 25, 2021, 10:25am

The fix was pushed in the stable 6.1.0 release per Releases · platformio/platform-atmelsam · GitHub, so using platform = atmelsam with the most up-to-date version of it (pio platform update atmelsam) is correct.

Is the error still the same “No device found…”?
