Question

Hello,

Does PmodSD (https://reference.digilentinc.com/reference/pmod/pmodsd/reference-manual) support SD mode of operation?

Is it designed only to work with SPI mode as written in the reference manual?

Please let me know

Regards,

Vinay Shenoy

Hi @Vinay Kumar,

In the reference manual here on page 1 it states that:

"the PmodSD is designed to communicate with the host board primarily through the SPI protocol. By default, the SD card itself is defined to boot up in SD mode, but will enter into SPI mode when the Chip Select line is pulled low."

It should boot up in SD mode if the Chip select remains high. We do not have any support for using the PmodSD in SD Mode.

thank you,

Jon
