You've got quite a bit of difference than just console on PSC3. USB
is on the Ethernet pin group instead of on the USB pin group. Does
the kernel change the value of port_config when it boots, or does it
leave the value setup by U-Boot intact?
As far as I sow from debugger no.
We are able to boot with a mini operating system (see previous post).
Plugging USB the system get frozen.
We have got the same version of kernel compiled on PPC ARCH and USB, in
this case, works.
Between PPC and PowerPC from debugger there is only one difference the
label for USB interrupt, in PPC is 50 in PowerPC is 134.
I've already checked CDM register and GPIO register and all are the same.
From USB register only one difference on HDDC values (not important
from my point of view).
Our processor frequency is different from lite5200. We are thinking that
scaling frequency processor to determine frequency of USB bus is
different in PPC and PowerPC. Other street we are looking for is some WR
patchs from lite5200 on PowerPC that are not accepted from our HW.
I still do not understand our bug with USB.
Have you got some suggestions or some test to be performed in order to find
out a solutions?
Not over a quick exchange via email.
Yes of course :)
Your kernel is too old and USB
debugging can be complex. I'd need to be working with your hardware
to figure out what is going on.
I see. We also wont debug USB.
