AM6442: Yocto Custom image stuck at ttyS init

Part Number: AM6442


Hello, I'm having a custom Linux Image (Yocto - 23.08 Kirkstone) that gets stuck during the boot at the ttyS intialization. 

Please find attached the log. I've noticed a drop of current from 100 to 85 mA when that happens. Do you have an idea of what would cause this behavior ? 

Thank you.

  • Looks like you have additional UARTs enabled beyond the SDK standard UART of ttyS2 (0x02800000) commonly used for console?

    Can you temporarily deactivate any additional UARTs (via DTS change) except that ttyS2 UART to do a test to see if you can boot to the console?

    Regards, Andreas
