TMS320C6748: which filesystem supports 16T SATA

Part Number: TMS320C6748


Hello Champs,

The sata example in psp uses RTFS filesystem which supports up to 32bit LBA (2T), which filesystem could support upto 16T sata?

Thanks.
Best Regards

    Hello Shine,

    There is no SATA driver in PRSDK and PSP is fairly old so unfortunately our expertise on this subject is limited.

    From opensource.com/.../ext4-filesystem

    Ext3 filesystems used 32-bit addressing, limiting them to 2 TiB files and 16 TiB filesystems (assuming a 4 KiB blocksize; some ext3 filesystems use smaller blocksizes and are thus limited even further).
    Ext4 uses 48-bit internal addressing, making it theoretically possible to allocate files up to 16 TiB on filesystems up to 1,000,000 TiB (1 EiB).

    hi Sahin,

    I want to use ext4 instead of RTFS in the DSP/BIOS system. The SATA driver still uses BIOSPSP_01_30_01. The chip I use is TMS320C6748. How should I achieve this? Please give me some suggestions. It would be better if you had the appropriate reference.


    Thanks.
    Best Regards
