Unable to upload to samd21_xpro

sampscl commented 6 years ago

I am unable to program my Atmel SAM D21 Xplained Pro. I have run pip install -U platformio and pip install -U https://github.com/platformio/platformio-core/archive/develop.zip on Ubuntu 16.04 and had the same results (ignoring the "Obsolete PIO Core warning...):

platformio run -t upload -v

It seems that openocd is being told to look for atmel_samd21_xplained_pro.cfg in the wrong place. That config file is in /home/user/.platformio/packages/tool-openocd/scripts/board/atmel_samd21_xplained_pro.cfg, not /home/user/.platformio/packages/tool-openocd/scripts.

An update: this command worked from the terminal:

/home/user/.platformio/packages/tool-openocd/bin/openocd -s /home/user/.platformio/packages/tool-openocd/scripts -f board/atmel_samd21_xplained_pro.cfg -c "telnet_port disabled ; program .pioenvs/samd21_xpro/firmware.bin verify reset ; shutdown"

Please re-test with the latest upstream (GIT) version http://docs.platformio.org/en/latest/platforms/atmelsam.html#stable-and-upstream-versions

Yes, that has fixed my problem. platform = https://github.com/platformio/platform-atmelsam.git
