Hi all,
I have a custom board (based on PocketBeagle design). I was able to flash the EEPROM and it boots up normally and I have access to the Linux command Line through UART0 interface. However, the board doesn’t show up as a USB device as the PocketBeagle does.
Any ideas how to solve this issue?
Regards,
Hi. The schematic of the USB0 is the same as they pocket?
Yes.
Here is the UART log when booting up:
