Part Number: AM263P4
Other Parts Discussed in Thread: SYSCONFIG

Tool/software:

Hi,

I have started developing on AM263P4-Q1 LP board with the following toolchain:

CCS 20.3.1.5
SysConfig 1.25.0

I have just run FreeROS hellow world example and I see that TCMA/TCMB regions are defined with a size of 32 kB (0x8000) while datasheet specifies 256 (128 + 128) kB for CPU cluster.

This size is also specified in some academy pages like https://software-dl.ti.com/mcu-plus-sdk/esd/AM263PX/latest/exports/docs/api_guide_am263px/SMART_PLACEMENT.html

Is there a way to fix TCM regions size in SysConfig or shall I switch to custom linker file?

Thanks in advance for your support

Hi Andreas,Apologies for the delay in response, this thread got dropped from my radar.

For now I will recommend to use the custom linker file.

I have raised a bug to get it fixed for future sdk release.

Hi Nilabh Anand ,

Yes in the meanwhile I had already created custom linker.

I kindly suggest to updated SDK and docs since here are several mismatches.

Thanks and best regards
