RE: OMAP-L137 Evaluation Module (Need API to access the MMC/SD?)

Started by NOR RIZUAN MAT NOOR March 19, 2009
Thanks to Michael Dunn & Andrew Elder for reply,
 
I don’t have any experience using Linux for embedded application, only using DSP/BIOS on TMS320C6416 (fixed-point), and didn’t use any CSL or BSL since my project is purely in C/C++. Transfer image using CCS, perform features extraction (pixel by pixel basis) and show the features extracted at CCS.
 
But now, for my current project, I have to deal with hyperspectral image compression and from Michael Dunn & Andrew Elder replies, it seems that I have to use Linux, CSL, GPL etc. Could anyone please show me the path towards using Linux in OMAP-L137. I know, everything is available on TI’s website, but there are so many pages and could anyone point me to the right sources to get started ? FYI, I don’t have Linux or even UNIX basic.. Have used Linux on desktop, but I believe it is the version with GUI that might be different with Linux for embedded application.
 
Please, your help is really appreciated. Thanks again to Mike and Andrew.
 
Cheers,
Rizuan

I too have a L137 EVM on my desk, but haven't had as much time as I would like to investigate it.

I have more of a general chip support type question. In the past TI has provided a chip support library to provide access on chip peripherals. In Linux the whole code base is under GPL, but I assume Linux can access many of the same peripherals. Does TI release the CSL under dual licenses then ? GPL for the Linux build the "old" CSL license for embedded DSP/BIOS type applications ?

If you are developing SW for the OMAP, Linux will support a file
system on a MMC or SD device.
