Intellectual 2325 points

hi,

1. Where can I get the documentation for ATAFS  filesystem. I couldn't locate this in the CSL lib documentation.

2. Is there any benchmark for ATAFS? the following info could be helpful.

 read,write capacity , Number of files can be created, speed of access of file, etc. & multi block read and write.

regards,

Frangline.

    Hi,

    The wiki doesn't say anything regarding available ATA functions. I have been searching for documentation but couldn't find any as well. After looking into source files, I couldn't figure out whether ATA supports opening a file conditionally, such as:


    OPEN EXISTING     Function fails if the file is not existing.
    OPEN ALWAYS        Opens the file if it is existing. If not, a new file is created.
    CREATE ALWAYS    Creates a new file. If the file is existing, it is truncated and overwritten.

    Any suggestion is greatly appreciated!

    Basic ATA library has no support for file open function. CSL example c55_csl_3.03\c55xx_csl\ccs_v5.0_examples\mmc_sd\CSL_MMCSD_SdCardFSExtExample\ata_ext_func.c has extended ATA functions to support file open, delete and change directory operations. Please take a look.
