C5535 MMCSD write

sam lai

Dear All :

I want to write some data on SD card through multiple write command. (DMA transfer)

Could anyone help me write data to SD card when setting MMCSD register MMCNBLK to 0 (sequential write) ??

Are you aware of the chip support library, C55XCSL: http://www.ti.com/tool/sprc133 ?

Refer to the CSL_MMCSD_dmaExample. Rest of the example would be a good leraning tools.

Regards.

I've tried the example in CSL library.

But the problem is there's no example to set the MMCNBLK=0.

Could you help us how to use the infinite sequential writing ?

The default value is "0". Use break points when running the example to trace this register value.

Regards.
