Dear All,
Now I'm trying to digging the M3 operation in especially reset sequence with hello example of cortex design kit.
Current situation is that reg14[31:0] is fixed in 0xFFFFFFFF and reg15[31:2] is 0xXXXXXXXX unkown value. the other regs are working as well.
Actually I hope that values will work as the image.hex but that reg14 and reg15 don't update.
But ironically the "test passed" printed.
Not sure but does anyone know what am I supposed to do to to see the normal operation ? how to resolve this problem?
Do they work if you read them from software?
Eg can you do something like:
mov r0, pc
mov r1, lr
this might also flush the update through the sim.
Thanks,
As your recommended, I could see that pc and lr values updating to r0, r1.
it means that pc and lr show as being work. but I don't get it why doesn't pc value update to reg15?
