TMS320C5515 MMC interface

Other Parts Discussed in Thread: TMS320C5515

About the MMC interface of TMS320C5515 DSP. I'm going to work with Samsung eMMC moviNAND flash via MMC interface. The Samsung eMMC flash is eMMC v4.41 compatable device that supports 4 bit data and 52MHz clock. Can I run TMS320C5515 with 4 bit data of MMC interface at 50MHz clock in fast mode as specified in Table 6-23 paragraph 6.10.2 or it will support only 20MHz clock with 1 bit data?

Thanks in advance

You can use the C5515 MMC interface in 4bit mode at 50MHz.

Hi,

C5515 supports 4-bit 50MHz. We have tested a different company's eMMC card.

Can you be more specific about your problem? Are you using CSL3.03 or 3.04 and following the steps in the INstallation Guide? Here is the link to CSL:
