Hi
In my board with am3354, I found that the USB1 HOST is not work; The USB1_VBUS pin is fixed to connect with 5V , and USB1_ID is connected to ground directly for USB1 HOST configure;
when power on the board, the logs show USB1 work at HOST mode, and USB1_DRVVBUS will have wave from Low to high, about several millisecond, the USB1_DRVVBUS be Low, then show a log message "VBUS error workaround (delay coming)";
Because USB1_VBUS pin is power by 5v directly, so I think regardless the USB1_DRVVBUS status, VBUS pin should detect a high status(>4.4V); So where maybe I mistake and need to check ?
below is the log of usb1:
root@am335x-evm:~# cat /proc/driver/musb_hdrc.1
