Hi,
my redboot stops while trying to execute memcpy in strata.c.
I get this message on screen: $T0a0f: 48350200; 0d; 10c800a0; #7c.
from earlier posts i understood that the above message means that
instruction @00023548 gave me an error and this corresponds to
23548: 848c3004 strhi r3, [ip], #4
from this i gather that while trying to write it failed.
Now, my doubt is :
1> Why it failed?
2> What address it is trying to write when it failed?( a000c810?)
3> has it anything to do with scrubbing sdram? ( 80310 chipset)
the code is running on xscale board.
Rgds
