Hi All,
For our own development board we face an issue regarding the USB host
controller. We applied al the patches from Robert C Nelson s tree, also
regarding the USB host issues on the beagleboard.
Our compiled kernel does work on the Beagleboard with USB host, but on our
own proto board (wich is different ofcourse compared to the BB but has
exactly the same schematical connection for the USB connectors) we cannot
get it working (Same Binary so Same Kernel Config).
Now we tried kernel 3.12 from the RobertCNelson tree, and supprisingly USB
is working on the BB, but also on our Proto board!
I generated a lot of kernel debugging on the OMAP Registers (control
module, USBSS, USB0 Core USB1 Core etc..) and posted them on Pastebin (See
Links);
Kernel 3.8 (Not working): http://pastebin.com/HaAb0U9Y
Kernel 3.12 (Working): http://pastebin.com/mSuy4UrM
So what we see is some differences in register values, but we dont really
know if they are meaningfull regarding our project. and also we printed the
entire memory region of the USB0 Core and the USB1 Core, but these are IP
protected by TI so the defintion of these registers are not known to us.
If anybody has any clue on how to proceed please let us know!
As mentioned before on this forum we got the SGX drivers working for 3.8 so
we are not that eager on jumping over to 3.12 directly, knowing what issues
kernel version change can have.
