AM335x SDIO Function

AM335x's SDIO supports both master(host) and slave(client) functions.

Is it right?

I want to connect the other CPU(SDIO master) to AM335x's SDIO(slave). Is it possible?

Hi Yang,

What do you understand by SDIO? If you mean the AM335X MMC[2:0] ports, these are master controllers only. You cannot connect the AM335X as a slave device via these ports.

Hi, Biser

Thank you for your reply.

SDIO means MMC controller.

There is no way to configure the AM335X MMC Host controller as a slave SDIO device.
