When using SEGGER JLink, I can't seem to read memory in the secure region from GDB. For example on the hello_world_ trustzone demo app in the sdk, I always see access errors for secure regions reads
(gdb) x/a *(uint32_t*)0x30000000
Cannot access memory at address 0x30000000
but non-secure regions work fine:
(gdb) x/a *(uint32_t*)0x20008000
Any ideas on how to fix this? Thanks!
