Chip Support Library for OMAP-L137

Arye Lerner

Hello,

I am trying to start optimization of software on OMAPL137. I refer to document "DSP Cache User's Guide" document number SPRU862B. This document refers to CSL and commands/constants used in cache manipulation is described in csl_cache.h, csl.h, csl_chiphal.h, etc.. header files.

However, I cannot find CSL that supports OMAPL-137.

Can anyone point me to where I can download it from?

I am using DSP/BIOS in my project, does it have an alternative module/routines/anything to mentioned cache optimization in CSL?

Regards

Arye,

The document you pointed was made more for C64xx family. The principles should work, but C64xx has a complete CSL.

The examples for C674x are based on DSP/BIOS drivers: PSP (platform support package).

Some of the newer components do not have a functional CSL anymore. This was replaced by the PSP, that is DSP/BIOS dependent.

Just to clarify, the traditional CSL (usually for the older parts) has two layers: the functional CSL and the register CSL. The register CSL is the basic parts with register access code. There are some examples that use the register CSL for C6747 at (after installing the software):

C:\Program Files\Texas Instruments\pspdrivers_01_30_00_05\packages\ti\pspiom\cslr\evm6747\examples

For the CSLr includes cache functions, please see:

C:\Program Files\Texas Instruments\pspdrivers_01_30_00_05\packages\ti\pspiom\cslr\cslr_cache.h

Please see the cache example at:

C:\Program Files\Texas Instruments\pspdrivers_01_30_00_05\packages\ti\pspiom\cslr\evm6747\examples\cache

Hi,

I have just one more qustion: what document describes this example (is there a OMAP Cache user's guide)? I see that the commands are little different.
