PROCESSOR-SDK-OMAPL138: Cache configuration

Yuehai Zhou1

Part Number: PROCESSOR-SDK-OMAPL138
Other Parts Discussed in Thread: OMAPL138, TMS320C6748

Dear Ti,

I have OMAPL138 evaluation board. Now I want to configure the IRAM (L2 RAM) from two parts, one is the cache that occupies 128 kB, and another 128 kB is the traditional memory that uses to run digital signal processing algorithms. Could you guide me how to configure this, including in platform files and .cfg file. Thank you very much.

Best regards,

Yuehai Zhou

Hello Yuehai,

What software are you running, and which core did you want to use to configure the RAM?

Regards,

Nick

Hi Yeuhai,

Are you looking for SYS BIOS APIs to configure the Cache? If your application is sys bios oriented, it is better to go with the SYS BIOS APIs.

I assume, you are familiar with the RTSC Cfg file for Sys BIOS.

Please take a look on the Cache module supported by SYS BIOS:

The API is same across all releases of SYS BIOS:

Let us know if this helps your needs.

Thanks
