Hi,
ether.c contains the following code :
req->buf = (u8 *) NetRxPackets[0]; req->length = size; req->complete = rx_complete;
retval = usb_ep_queue(dev->out_ep, req, gfp_flags);My USB controller code that I'm writing responds that req->buf is NULL. So the OUT packets don't get processed. I know OUT data arrives in my controller code as I can read it, so my OUT endpoint is working. Also my status endpoint is working correctly and my guess is there's nothing wrong with my controller code.
Anyone have an idea how NetRxPackets is allocated ?
Nobody ?
req->buf = (u8 *) NetRxPackets[0];
This is returning an non existing buffer for some reason and I know not much about the ethernet layer to fix this. My guess is I miss some define (eth related) somewhere but I'm also about to give up on ether.c and just port a more simple driver to u-boot for testing USB device controller drivers.
Any ideas why this could happen or how I can find out why that is ?
Best regards, Marcel
