Hi there,

Thanks for the reply!

I'm glad that it works on your R2D-1. Both my R2D-1 boards do not have
working CF. Just to double-check - are using a R2D with one or two pci
slots?

Yeah, maybe it is related to fpga version. I sort of assumed that the
option CONFIG_RTS7751R2D_REV11 was a complicated way of switching
between R2D-PLUS and R2D-1. But maybe it's related to fpga version as
you suggest. I have no idea.

Right. It looks like the IRL level should differ, but I get the same
IRL level for both R2D-1 and R2D-PLUS.  Maybe my R2D-1 boards are
special...

Not sure which revision, but everything except CF works for my R2D-1
and R2D-PLUS boards...

Sure, if that what it takes. I need to look into this more.

Can you please post the BVERREG and VERREG register values from your
R2D-1? Then I'll post mine when I get back into the office.

Have a nice weekend!
