SD Card Read/Write for TMS570LS3137ZWT?! Please help!!

Other Parts Discussed in Thread: HALCOGEN

Hey guys,


I've browsed through nearly every forum post on E2E that has any relevance to SD card read/write, and I still haven't been able to come up with a suitable way to read/write data from my microcontroller to an SD card that I have. I have tried using the connectivity test code and literally every piece of other test code that others have posted but to no avail. It cannot be this hard, right?


Does anyone have any demo code for actually reading/writing files between my Hercules and an SD card? If so, could you please please please post it? I would be so immensely grateful.


Please help!


Best Regards,

-HL

    Hi HL,

    I wrote a CCS project for accessing SD card on RM48 HDK. The project also contains a simple FS. I posted on another thread before.

    QJ,

    Thank you for your reply. I have been messing around with trying to get your demo code working on my TMS570. You mentioned changing PLL and endianness in your other thread. Could you please elaborate on this?

    I am rather new to TI microcontrollers, and I'm really not sure how to even get started on converting everything to work on my TMS570. Should I rebuild using Halcogen and copy the SDCard and fatfs folders? Otherwise, how should I edit the demo code?

    Any help would be appreciated! Thank you so much for your help!

    Best Regards,
