Well, do you have a good explanation why the system works
with this change and doesn't work without it on my design
? I'd really love to understand this.

Do you modify the driver to setup the translation table?

No, I didn't change the driver. What do you refer to please ?

There is Address Translation Table at address offset 0x1000 in
the IP.

Oh, I didn't configure that in any way. Should I or does the
driver configure it in some way?

Do you use the hardware design from the rocketboards.org or
your own design?

I use the one from rocketboards, I just ported it over to the
MCVEVK (custom cyclone v soc board)

You may check again the base addresses use in the MCVEVK board.

The address map is attached ; I don't see anything which would differ
from the reference design.

Address map looks fine.

Well do you have any other idea then ? I guess I should pull out the
SOCDK, huh?

Can't think of any other thing that impact this, I expect the bus width
used in the pipeline/bridge are same with the example design.
Do you have our CV, AV or A10 SoC devkit?

I tested CV SoCDK just now and you're right, the provided quartus project
works without this change on the CV SoCDK. Do you have any suggestion for
me where I should try looking then please ?
