RE: Bad Magic Number

Did you wrap the kernel image using the ppcboot
mkimage tool? If not, have a look at the ppcboot
documentation on mkimage it explains everything
you need to know.

Hi all,

Can anybody please explain the error and suggest any solution for it.

Thanks in advance,

USB Isochronous for MPC823

[Nguyen Trung Thanh]

Hi all,

I've tried to use m8xxhci.c from Hardhat2.0,
but I saw that it still has a bunch of errors.

I did make many changes, and it could run with control msg, and bulk msg.
However, it's not fully reliable, of course because I'm still testing it.

Now, I am stuck with Isochronous msg.
Have you done it before? Or do you have any information that I need to pay
attention to?

I read in the spec of MPC823, it just said that I'd take care of TM bit in
USEP, (transfer mode for endpoint 0).
Then I modifed that code, to change this TM bit according to BULK, ISO or
CONTROL msg.

Pls help me to make the usb audio driver run on MPC823.
I'll try to make it reliable.
Thanks,
Jari

The USB on 8xx isn't going to work properly without the
proper chip revision, matching microcode patch, and specific
board modification (8xx pin loopbacks).  Have you read the
Motorola errata, USB application notes, and properly followed
those?

Hi Dan,

I've read those docs already, and I didn't use microcode patch,
I handled 1ms interrupt by myself.
However, I'll check them again.

I think that they're just some configuration or controling the interrupts,
I'll try that right now.
The board I'm using now is RPX-Lite.

Thanks for your fast reply,
Jari
