Writing to SD Card- OMAP-L138

Hi Tariq Siddiqui,

Please visit the link http://software-dl.ti.com/dsps/dsps_public_sw/psp/BIOSPSP/01_30_01/index_FDS.html and download the package (installer). Go through the userguide before using it.

This could be useful for your requirement.

Sandeep

Hi Sandeep,

Thanks for your help.

Yes, I found that already and tried to run the sample code but it doesn't work. I keep getting the message 'Please insert the card' !

Apart from that, it looks so complex code, my project is based on BIOS, how can I simply use WRITING to SD card function to write some processed data from my existing application code ?

I would really appreciate your help.

Tariq

Will any one please respond to this post ?

Hi Tariq,

I have requested the PSP drivers team to help you with this.

Thanks Ashish.

Hi Tariq,

Are yo uusing the EVM or the custom board?

You need to insert the card. The card will be detected using the GPIO. Once after this read/write will take place on the card.

Hi Sandeep,

I am using EVM. I tried with 8GB Sandisk and 4GB Card came with EVM board. Attched below is the screenshot of Raw Log, you can see it continuously says 'Please insert the card'.

I am using PSPDRIVERS_01_30_01, mmcsd sample code.

Waiting for your help.

Hi Tariq,

You can download RTFS package from here http://software-dl.ti.com/dsps/dsps_registered_sw/sdo_sb/targetcontent//bios_file_system/index.html and refer the mmcsd example @ “\rtfs_1_10_00_30\packages\ti\rtfs\examples\mmcsd\bios5\evm6748”.

Ashish,

I didn't find RTFS package for OMAP-L138 platform ?

Waiting for your help.

Tariq

Hi Tariq,

I believe we do not have a RTFS example for OMAPL138. You can refer the C6748 example to create your application.

Hi Ashish,

I don't know how to modify C6748 example to fit my application. Please help fixing the PSP based mmcsd sample code. That code compiles fine but doesn't recognise the SD card.

What should I do ?

Thanks.

Hi Tariq,

I have requested Sandeep (from the PSP team) to help you with modifying the example.

Best,

Ashish

Hi Ashish,

I really need to do it as soon as possible.

Thanks.

Hi Tariq,

Can you please try with 1GB or 2GB SD card? 

Thanks and Regards,

Sandeep

Hi Sandeep,

I don't have 1 GB or 2 GB SD card. I will get back to you soon.

Any other advise meanwhile ?

Tariq

Hi Sandeep,

I tried with 1 GB SD card but no success. Attached is the snapshot of Printf Logs.

Card is still inserted and it does nothing after printing those messages.

I will appreciate your quick help as I am already running out of time.

Thanks.

TI Guys,

Can you please reply to my post ? It's been more than a week now.

Thanks.
