I'm using 21489 for a project but we come across with this problem.
first we wrote a bit of code and then we find out that the SIMD bit in MODE1 register is disabled. So we enabled it and we got this error during running (compile ok)
[Error si3002] Invalid fetch address. At cycle 0x15afe: Fetch override = 0x13 specified with reason "Branch override" at PC 0x124a63 is in IOP space.
we changed it back it was ok again.
so i need some guidance about what does this error means and what can possibly caused it.
