Hi,
Is there any way to restore the bootloader on a TinyML board? I tried some alternative methods of flashing the FW, but unfortunately, this caused the COM port to become unavailable after connecting the TinyML board to the PC. It seems that the bootloader is corrupted. Is there any way to fix this?
Thanks.
Hi @Kroun1 ,
Thank you for reaching out to us.
Kindly try the given steps.
In case you encounter issues related to your USB port, make sure that the USB Dongle is plugged into the computer.
- Open Device Manager
- Click on Ports
- See if there is a symbol showing an exclamation point inside a yellow triangle in front of the USB port that corresponds with the board(Arduino MKRZERO)
- Right click on the port corresponding to the TinyML board (ARDUINO MKRZERO) and click on uninstall
- Now unplug the board, then plug it back in
This should resolve the issue related to COM Port.
Let me know if we can assist you further.
Thank you.
