5509 file system - peejayblack - Dec 9 4:24:00 2003

I see that the 5509 supports MMD/SD but have seen only block read an wright routines from TI app notes. Can anyone suggest a good file system layer to go on top of the block read & write support TI has provided? Thanks Phil |

We have spent quite a lot effort to get SD card working and succeeded. We have also got DMA driven read/write routines working, which TI has not yet implemented. Licensing of our library might be possible, in case of interest, please contact for further questions. It is also possible TI will update their CSL in respect of better SD/MMC support, but I have heard no official statement from TI concerning the issue. > Can anyone suggest a good file system layer to go on top of the > block read & write support TI has provided? There is no existing file system driver provided by TI that I know of. Simple FAT file system layer shouldn't be hard to implement as it's quite well documented.
