Original question:

AM623: USB probe failed

AM623: AM623: USB probe failed during uboot startup

Part Number: AM623

Hi, TI expert! 

I have a development environment for am6234, with our own evaluation board.

The software SDK version is PROCESSOR-SDK-LINUX-RT-AM62X-08.06.00.42.

I inserted the USB flash drive into USB0 in the evaluation board, and then powered on to start the evaluation board.

During the uboot startup process, the following error occurred. How can I resolve this error?

There were similar issues in the kernel before, as described in the following post

https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1314236/am623-usb-probe-failed/5005849?tisearch=e2e-sitesearch&keymatch=%20user%3A565545#5005849

After merging the patch in the above post, the issue of the kernel being unable to detect the udisk has been resolved.

However, after the system performs a reboot command, there may occasionally be a problem of Uboot being unable to detect the udisk。

Regards,

Li
