Eclipse with Seeeduino LoRaWAN : bossac problem

Products & Technology Arduino & Seeeduino
#1

Good afternoon,

I have successfully installed the Seeeduino .json support package into a Windows-10 Eclipse 2019-06 CDT environment and this has compiled and linked my project files cleanly into a .bin file, ready for download to my LoRaWAN board on COM4.



Problem: The ‘bossac’ download command terminates reporting an error “Unsupported Cortex-M3 architecture”. This is weird because the processor is SAMD21, which should identify as Cortex-M0.



Question: Is 1.6.1-arduino the correct version of bossac for this board? If not, could you please advise how I can proceed?



Details: The full command is </s>.../.arduinocdt/packages/Seeeduino/tools/bossac/1.6.1-arduino/bossac.exe -i -d --port=COM4 -U true -i -e -w -v ./DemoNode.bin -R<e>

Console trace shows…
</s>Set binary mode readWord(addr=0)=0x2064654c readWord(addr=0xe000ed00)=0x6e727574 readWord(addr=0x400e0740)=0x6f206465 version()=ff! chipId=0x6f206465 Unsupported Cortex-M3 architecture Send auto-baud Set binary mode readWord(addr=0)=0x2064654c readWord(addr=0xe000ed00)=0x6e727574 readWord(addr=0x400e0740)=0x6f206465 version()=ff! chipId=0x6f206465 Unsupported Cortex-M3 architecture No device found on COM4<e>

Many thanks, Dave.

Hi Dave~



Sorry, we do not use the eclipse. We suggest you to use the arduino ide to program the seeeduino lorawan. We use the latest one 1.8.9.

You can select Seeed SAMD Boards in board manager. thanks.

Thank you for replying, bill.yu.



Yes, I already have my code working under the latest Arduino IDE.



I was wanting to port to the Eclipse-IDE because some of our existing TI-CC13xx projects use it and, to be quite honest, Eclipse provides much more powerful features than Arduino.



I guess it was the <LINK_TEXT text=“http://wiki.seeedstudio.com/Eclipse_IDE … Phone_Kit/”>http://wiki.seeedstudio.com/Eclipse_IDE_for_RePhone_Kit/</LINK_TEXT> link on the Seeed Wiki that led me to think there was general support for development under Eclipse. A great pity because it almost works… as I said, the only outstanding obstacle seems to be the version of ‘bossac’ included in the Seeduino .json support bundle.



Please could Seeed consider Eclipse support in the future. Best regards, Dave.
