Is RTFS supported on C6713?

Other Parts Discussed in Thread: OMAP-L138

Hi

Can anyone say if RTFS (for FAT32) is supported on C6713 (with DSP/BIOS 5.31.02).

Regards Sati

    Sati,

    DSP/BIOS is a single-process, multi-thread OS intended for embedded signal processing applications. It does not include native support for higher level functions like a file system.

    You could certainly implement one on it. And you can find some information online about porting Linux to our C6000 family of DSPs. I am not sure how beneficial that would be, but perhaps it is a direction you might find interesting.

    Please let us know what you end up with or what you learn about this.

    Regards,

    Hi RandyP

    Thanks for the reply.

    If I swap to SYS/BIOS on C6713 (instead of DSP/BIOS). Would it enable me to use RTFS (or does SYS/BIOS ver 6.45 contain any built in support for FAT32)?

    The DSP I use is TMS320C6713. 

    Regards

    Sati

    Sali,

    Since this is the C67x Single Core DSP Forum for hardware device questions, I will request a Moderator to move your thread to the BIOS Forum for definitive answers to your BIOS questions.

    The C6713 is a very capable DSP, and can provide the performance needed for many signal processing applications. The C6713 is also fairly old in terms of technology advances. There are quite a few newer DSP that are upward compatible from the C6713, but that can deliver more performance without costing you a lot more.

    BIOS was developed to make it easier to get those signal processing applications running. It is lightweight in terms of memory space and performance overhead, and it includes features that make it easy to capture/process/deliver digital signals.

    You may want to consider newer devices, such as the OMAP-L138 that has both a DSP C674x core and an ARM9. The ARM9 can run Linux, which would give you a quick path to your file system.

    For direct answers to your BIOS questions, we will see what they say in the BIOS Forum.

    For what purpose do you want a filesystem for your DSP application?

    Why are you using the older technology of the C6713? I recommend moving to the OMAP-L138, C6748, or C6655/57.

    Regards,
    RandyP

    I fully agree with you suggestion of using a newer device but, this decision  I can not take by myself at the moment. 

    Regarding your question:

    I need filesystem since I have to read / write data on SD card (using SPI interface) .
