Execution stopped in Secure Privileged Thread mode at 0x00000000

Hi,

I've realized that the main root cause was not the Security Mode change but actually the a scatter file change i did.
Originally the load address which is equal to execution address was set into address 0x0000000. Later on I've changed it into 0x11000000.
It seems like 0x11000000 is forbidden or alike (belongs to Vendor_SYS memory region which instruction fetches are not supported).
Do you think this is reasonable?

Moreover, please let me know how can i use compilation flags inside the scatter file itself?

Thanks,
Ronen

Hi Ronen

This address is marked as secure in the FVP:
https://developer.arm.com/documentation/100966/1118/Arm--Corstone-SSE-300-FVP/Memory-map-overview-for-Corstone-SSE-300

Unsure what you mean by using compilation flags in the scatter file... do you mean preprocessing?

Regard, Ronan

Hi Ronen

Yes, as Ronan wrote earlier, see developer.arm.com/.../Preprocessing-a-scatter-file

For a simple example, see scatter.scat in the "startup_Cortex-M7_AC6" example supplied in Arm DS.

Hope this helps
