Implementing File system for saving video onto Sd card

Vivek Jayakrishnan

Other Parts Discussed in Thread: OMAPL138, SYSBIOS

Hi,

I am working with the OMAPL138 LCDK for the first time. Thanks to help from many like Titus in this forum, I have been able to do a lot of examples that came with the starterware. My objective is to record videos on sd card. If I am not wrong, I would need to use RTOS for this right? If so which one MCSDK or SYSBIOS?

I have never implemented a FAT file system. I did not find any examples also of mmc for this board. Are there any resources of TI on File system implementation ?

thanks

Dear Vivek,
You can find the MMC/SD based examples from the BIOSPSP package.

Thanks Titus,

That's something I can start working with. By the way do the file system implemented in the above said examples allow me to save a video real time. Would it be that fast enough??

Yes, the example does support FatFs filesystem and it would be fast if you have modified the code as per the given E2E post.
