Chestnut board lost connection (being undetected) via com after code upload

[rschung]

Dear designer and friends, did anyone ever encounter this issues ? When i installed Chestnut board and uploaded the code, then I found my Chestnub board cannnot be detected anymore by PC via the #com port. Until i cleaned up everything and reinstall the bootloader on the board, the chestboard can be detected again, but the lost connection problem came out again after i reuploaded the Chestnut code. Getting stuck here for a long period. Wish friends here can help. Thank you !

Hey, my board does the same. Most likely wiring issue. Tried on Windows 12 and Pop!OS 20.10. In my case disconnecting power for a couple of seconds has helped.

I have found the same issue, I am wondering how exactly did you "clean up" everything? Because as of now the only way I can interact with the hand (USB connection) has been eliminated because of this issue. I have seen there is the possibility of using the bare TX RX connectors on the board, is that the only way to communicate with the board at this point?

I am having same issue. I can get the board to reconnect by clicking or double clicking reset to ground. But only to get the bootloader to run again. I have not been able to see the menu or issue commands. Curious what LED2 signifies. Will do some drilling through the code to try to figure it out. But it is a sort of orangeish color. And it blinks steadily when it is generally running. I can get it to be steady and that is when the Com comes back. But no other signs of life. Motors initially twitch when powered on. Also certainly possible I have wiring issues.

Please tell me guys, which version of Arduino IDE, Open Bionics Boards and and the SAMD board board library work together?
