Dear team,

I would like to ask a quick question about SD module of i.MX6Solo.

In case of using i.MX6S with two SD card port, can I understand that one port can support SDXC while the other port can support SDHC only?

My customer found the description as below in your WEB site.

“Expansion Ports; 3x SD/MMC 4.4, 1x SDXC”

Thanks,

Miyamoto

refer to  the refence manual, the uSDHC module is capable of SDXC, so all 4 SD interfaces should be capable. The limitaton is which one's has the signals muxed out.   Whether sdxc is supported is a feature of the board. For instance, on the SABRE-SD there is no support for SDX. Whereas on the SABRE-ARD, SD3 is capable of SDXC.

Hello Joan,

Sorry for my late response. But let me clarify my understanding.

> The limitaton is which one's has the signals muxed out. 

Can I understand that sometimes user cannot assign multiple SD ports on their own board due to IO-MUX?

 

Thanks,

Miyamoto
