Arm R52 FVP mode memory write is and access throwing controller to abort handler

Hi all,

I’m using Arm Development Studio 2025.0-1 with the FVP_BaseR_Cortex-R52 model.
My goal is to access and write to an SRAM region that lies outside the default fixed map provided by the Base model (for example, address 0x0600_0000 or 0x0800_0000).

However, whenever my code tries to write to these addresses, the execution goes to the data abort handler.
In the Memory Browser of Arm DS, those locations also appear as unmapped / inaccessible .I am running my baremetal code on this platform.

1. Does the FVP_BaseR_Cortex-R52 model support access to external DRAM or extended SRAM regions beyond the default RS2 map (e.g. 0x0600_0000 or 0x0800_0000)?
2. If not, is there a way to enable such memory (for example, via model parameters or configuration file)?
3. Would switching to the FVP_Corstone-R52 model be required to get a full Secure/Non-Secure memory map, and if so, where can I download it from and is it part of evaluation license?
4. Any way to visualize or extend the Base model’s memory map within Arm DS?

Thanks and best regards
