AM4377: USB1 host mode does not work

Sung-IL

Part Number: AM4377

Dear Champs,

My customer found USB1 host mode was not worked and there was no signal at the USB1_DRVVBUS.

Could you please check attached dts file and mux.c file for USB1 host mode?

They checked it on UBOOT only now as they failed to run kernel yet.

Their SDK is Linux PSDK v6.03.

Thanks and Best Regards,

SI.

Hi SI,

I cannot review the attached files. If the customer made any change to these files, please provide the changes in patch format.

Please describe how exactly the USB1 port is tested in U-Boot? Did the customer run 'usb start' command in the U-Boot prompt?
