Adafruit feather M4 CAN does not upload

there seems to be an issue with the adafruit feather m4 CAN board and uploading. bossac-tool complains "bossac: extra arguments found".

First it seems like the port is not passed correctly to the bossac tool. It passes it as --port "ttyACM0" while it should be --port=ttyACM0

The second problem I found, there is no offset passed to the bossac-tool. this is due to the main.py L220:
if board.get("build.core") in ("adafruit", "seeed", "sparkfun") and board.get( "build.mcu").startswith("samd51"):

In my opinion it should be:
if board.get("build.core") in ("adafruit", "seeed", "sparkfun") and (board.get( "build.mcu").startswith("samd51") or board.get("build.mcu").startswith("same51")):

No this seems to be another issue. They got the error No device found on COM5 *** [upload] Error 1

My error is bossac: extra arguments found

Hi @mansk789 , thanks for reporting! I've just pushed a fix and now the offset value should be also used for SAM E51. I believe this should also fix your first problem with the bossac: extra arguments found error. Could you please try to run your project using the upstream version of the platform (a Git client is required):

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

Hi @valeros
Works like a charm, thanks for the quick fix! Do you have already a timeline, when the fix will be in the production code? (just for my info, no rush :) )

Thanks for confirming, a new release will be published by the end of this week.
