Hello,
I wonder if there is no default memory map on Cortex-R52 processor.
In the case of Cortex-Mx processors, I can find out the default memory map.
For example, Table 3-1: Default memory map on Arm Cortex-M33 Processor Technical Reference Manual Revision: r1p0.
But, I cannot find out it on the R52 Technical RM.
Can you let me know why the R52 processor does not have the default memory map?
Best regards,
Ethan
Hello Ethan,
Basically this is to give designers flexibility.
Few things are mandated. The vector table has a defined format, and the ATCM, if present, is at 0x0.

The closest equivalent for the Cortex-R52 is the default protection regions used when the MPU is disabled:
Arm Cortex-R52 Processor Technical Reference Manual
The actually memory map of the SoC containing the Cortex-R52 will be up to the SoC vendor, and there could be a lot of variation between different SoCs.
