Hello everyone. I was wondering if anyone else has run into an issue with the seeeduino chip disappearing from the view Linux (Ubuntu 20.4). I am following the instructions on the wiki, but it fails to upload. I tried twice before rebooting. I have been successful with the code on other odyssey boards of the same type (previous orders of X86J4105’s ) . Every board in my latest order seems to have this issue. I used the same code each that I have previously. After attempting to flash the 1) Arduino code to the seeeduino chip & 2) rebooting, the SAMD is not seen in Ubuntu 20.4 using the command lsusb and I do not see ttyACM0 any longer in the /dev/ folder
lsusb, the seeeduino is listed as
Seeed Studio Seeeduino Zero, on the Odysseys that don’t work, prior to attempting to flash, the seeeduino was listed as
Unknown Seeeduino_Cortex_M0+. I am not sure what the issue is, but maybe the bootloader on the SAMD was bad in the boards I received in my latest order (previous orders I have not had a problem). Again, I am not sure if the bootloader is the problem, but does anyone know is it possible to reinstall it? If so, how? Any other ideas what the issue may be? Any help would be greatly appreciated. Thanks.
