Hi,
I'm working on customized am3359 board, which has same usb part schematic as beaglebone black A5C, I use uboot psp 06.00.00.00 and linux psp 04.06.00.11, after login root, console outputs "ti81xx_interrupt 1146: VBUS error workaround (delay coming)" periodically and usb function can not work.
I've try some methods as:
in uboot prompt, execute "usb start", it says, "lowlevel init failed"
modify hardware, add cap on VBUS to 200uF, directly connect 5V system power to VBUS, all failed to solve it.
I checked VBUS, it's stable on 5V, seems software issues, but I can't find where to modify something, could anybody advise?
Thanks a lot!
