Dear TI,
I am not familiar with file systems but was curious if you could outline how I would read a jpeg image from nonvolatile storage on the C6748. It is my understanding that the two most popular interfaces are NAND and MMC/SD Cards. I obviously want to avoid as much lowlevel implementations as possible and want to abstract a lot of the details away so I can open the JPEG file and load it for display. Can you please comment on my understanding of your software that is available? Also, if someone could call to discuss with me that would be appreciated (414) 559-8600.
1.) SD Card Support - There are file systems available in both StarterWare and SYSBIOS that will allow you open files on an MMC/SD Card. Both of these insantiations abstract the low-level MMC/SD Card interface and all the top level api does is have to open and close the file within the filesystem. We currently use DSP BIOS and have been looking at the RTFS vs Starterware. Can anyone elaborate on the pros/cons of either impelementation?
2.) NAND Support - There seems to only be file system support in SYSBIOS for the C6748. Does this structure handle the block read, block erase, and ECC handling that is present on all NAND devices? Again does it abstract away all the low-level details of the hardware?
I have more questions but would appreciate if someone could comment on whether I am going down the right path in my understanding.
-Jason
