Part Number: TMS320DM355

We have a product still using DM355. It couldn't pass RE test for new Standard.

The failure cause is SDIO rate exceeded the standard.

My question is:

Does DM355 have registers to change the SDIO rate?

Thanks.

Hi user4256924,

The MMC/SD card controller has the following feature: Programmable frequency of the clock that controls the timing of transfers between the MMC/SD controller and memory card.

For more info refer to the below pointers:

www.ti.com/.../tms320dm355.pdf - see section 5.8 MMC/SD

www.ti.com/.../spruee2c.pdf - see sections:

3.11 SDIO Card Function
4.2 MMC Memory Clock Control Register (MMCCLK)

Regards,
Pavel
