Hi, I have just tried this but it isn’t the fix.

Have you tried different USB cables.
Is the MCU flashed properly?

5

Yes, I have multiple cables that I have tried, i have used power and data cables but same problem.

How can i check if the mcu is flashed properly?

Are you still having problems?
post log.

When you run the flash command, the output tells you if the flash is complete. You can use lsusb in the terminal to see if the hardware is connected.
