I am using a custom image on the BitsyXb (I do not think I removed anything dealing with USB) and am seeing some strage USB behavior. It seems that sometimes the USB client will not load. Sometimes it will. If there is a usb mouse attached, it seems to happen less often. If you are looking at the hyperTerminal output during bootup, you will see:

The regular version of the OS from ADS does not have this problem. One other thing I noticed was that sometimes the screen on the dev kit goes to the white screen, but then just flickers lightly, finally going to a blue (the background color) flickering screen. I am not sure if the two things are related.

Hi Tom. Thanks for your note.
It does look like your USB Client driver is breaking (data aborting) during boot. It's not clear from the error message if "client" refers to the port (ie. the upstream USB) or the downstream driver that runs on the USB host port. From your description, it sounds like it may be related to the latter.
Your best bet is to see if you can create a standard build from the BSP that doesn't have the failure, then figure out which component(s) may be affecting the USB host driver by adding them back.
We don't offer support for building your own image on the forums, but you can contact us directly for further suggestions.
Cheers, Drew |
