DS5 code execution in RAM problem... again?

VERSION: ARM DS-5 v5.24.0

In the older version ARM DS-5 v5.23.1,  I was able to push a block of executable code to 0xC0000000 using the Base_AEMv8A->Bare Metal Debug->Debug ARMAEMv8-A

target.  I could write a blob of assembly and BLR X0 <- X0 = 0xC0000000.

This worked just fine.

Now it's attempting to branch and causing an exception.

Last time (previous version), I had to hunt down the documentation (which is a nightmare to find) and locate the memory map.  Is 0xC0000000 no longer mapped to SRAM?

Thanks,

geno
