RE: R_WAITSTATES register
Did you rebuild the kernel with e.g. make kernel (depending
on which developer board distribution you are using)? You can
check that the kernel has been updated by running
"boot_linux -F -p" and check that the output includes 0xff95f8.

Subject: R_WAITSTATES register
I've modified the R_WAITSTATES register in order to add some wait states for
external peripheral located in csp0 address area.
Using "make xconfig" I change the default value 95f8 to ff95f8.
I expect to have : zw (turn off wait states) = 3
ew (early wait states) = 3
lw (late wait states) = 15
When I look at the signals on the Etrax bus for exemple the delay between
csp0 and rd, ew seems to be 0.
It seems that the change in this register has no effect on the bus timing
Does anyone have an idea ?
