TMS320F28377S: Memory allocation for CLA programs and data

Part Number: TMS320F28377S

Hi experts,

The following linker command file is defined with PAGE = 0 in both the program area and data area of CLA.

In the case of CLA, is it not necessary to divide it into PAGE0 and PAGE1 like C28x?

C:\ti\c2000\C2000Ware_3_04_00_00\device_support\f2837xs\common\cmd\2837xS_FLASH_CLA_lnk_cpu1.cmd

Hi Sasaki,

Apologies for the delayed response.

In fact the usage of the PAGEs are not required for the new compilers, If you refer to cmd files of newer devices, we do not provide any PAGE info in teh cmd files.

The LSRAM is configured as CLA data memory or program memory in the application by setting Memcfg registers.

Regards,

Veena

Hi Veena-san,

Thank you for the information.

I understand.

As you say, the F28002x linker command file did not have PAGE information.

By the way, which version is the new compiler version?

HI Sasaki,

Small correction- We used different pages for the older devices since they had different buses for program and data memory. Details here : https://software-dl.ti.com/ccs/esd/documents/sdto_cgt_Linker-Command-File-Primer.html

In F28377S, the LSRAM address is the same in program space and data space. So, in effect, it should not make a major difference

Veena
