Tool/software: Linux
Struggling with getting USB working when transition from old TISDK without Device tree to new with Device tree support. The TISDK Im testing now is 04.01.00.06. I finally got the USB ports recognized by the kernel.
I figure I have some problem with VBUS due to the following line from the boot:
[ 2.218568] musb-hdrc musb-hdrc.0: VBUS_ERROR in a_wait_vrise (88, <AValid), retry #3, port1 0008010c
I dont see any voltage on the USB. And when I measure the voltage at USB0_DRVVBUS I see 0.8V.
This is how the scematics look, I have tried adding 200uF at C118.
This is the output from the boot:
