Hi Matthias,

it's working. I modified the testing-USB branch to run against a PCI OHCI controller (Philips ISP1561) on the APC405 board (PowerPC PPC405GPr).
Enumeration and USB storage is working. I do not dare to say 'working well'.
The main changes concern endianess fixes. The former code only supports OHCI controller with the same endianess as the CPU. The other fix allows a offset
IIRC same problem with the 440EP and MPC5200, thats what the extra #ifdef in drivers/usb_ohci.c:103 is for.
to access the system RAM by the busmastering OHCI controller. I called this constant CFG_PCIRAM_BASE. But the name is a little bit confusion, isn't it?
Here are my (first) questions:
- What do I have to do in usb_board_stop() and usb_board_init_fail()?
My current code can only initialize the OHCI controller once. A 2nd 'usb start' does not find any devices.
You might not have to do anything, but maybe you'll need to do some board dependant cleanup for example. If not just leave them empty.
- I had to disable the 'return -1' statement for an unfinished urb in
sohci_submit_job(). Why isn't it finished?
I really don't know, I guess only you can answer this!
Please do not blame me for the board dependent code still in the usb_ohci.c file. I will move it later.
Who else shall we blame then ;-) ?
