Dear all,
I am struggling to get networking up and running on my Atmel at91sam9260-ek.
I am trying to use an ASIX USB dongle. I got pretty far. Here is the
console log:

Could anyone give me a hint, what to do?
Best regards,

HI Holger,
+Cc Lucas who has also some patches in the Asix driver.

I have a AX88772A running here and it works fine on an i.MX53 board.
There are some things you could try. Do you have some other hardware
you can test? Like another board or another USB dongle? I do not really
trust the OHCI driver.
The Asix code is directly derived from the kernel. the asix_rx_fixup()
looks quite different there now, so it could be that the barebox code
has a bug in this area.
If that doesn't help, could you add a
memory_display(buf, 0, len, 4, 0)
to the top of asix_rx_fixup_internal() and post the result?
Also maybe Lucas has an idea.
Sascha

Dear Sascha,
the ASIX USB dongle is working on the same hardware running a 4.4
vanilla kernel. The dongle also works on my Linux PC with a 4.13 kernel.
I added memory_display(buf, 0, len, 4, 0) to asix_rx_fixup(). Here are
the logs:

Hm, comparing that to the traffic my device receives that may look
somewhat shifted. Do you have CONFIG_MMU enabled? If yes, please try
with MMU disabled. Also, maybe the buffer is not sufficiently aligned.
Could you print the pointer address of buf?
The buffer is statically allocated in drivers/net/usb/usbnet.c:
static char rx_buf[4096];
This looks fishy. It should be allocated with dma_alloc() instead.
