Hi,
we are porting ecos for ixp425 we have flashed the image as
per the sugessition in the forum but we are running in the infinite loop at
this point
icache_boundary:
// Here is where we switch from boot address (0x000000000) to the
// actual flash runtime address. We align to cache boundary so we
// execute from cache during the switchover. Cachelines are 8 words.
str r1, [r2, #IXP425_EXP_CNFG0] // make the EXP bus switch
nop
nop
nop
nop
----> mov pc, r0
nop
where the instruction says pc value to load into r0 is at the same
location and it goes into infinite loop and never stops execution
if i change the pc to ignore the step mov
pc,r0 then the code is allowing single stepping but the instruction is not
getting effected
can any one help out to sort this problem.
thanks & regards,
Sumanth
