Hi,
Thank you very much for your response.
For the interrupt, I'm sure it works because during the c67x00 probe,
the interrupt function is activated (c67x00_irq), the ACK from CY7C67300
is received, and the SIE interrupts are received too.
Do you remember if the SOF/EOP interrupts were activated?
In a first version I used of_irq_to_resource() (I added the interrupt
port number linking the Cypress and the Xilinx xps_intc controller) and
I red that the interrupt for Cypress CY7C67300 in PowerPc was 17. So I
added this number in c67x00_resources[] to avoid to use OF support.

It is strange that the little writing works and not the big one...
The lecture is ok, even with a big file. For example a cat "file.txt"
works and the file is printed to the consol.
Here is the trace of the writing:
The first c67x00_ll_husb_reset are ok but then crashs...
