iMX6UL uSDHC 1 or 2 interfaces

johandeben — Tue, 17 Nov 2015 14:58:28 GMT

I'm wondering if the iMX6UL-1 has 1 or 2 uSDHC interfaces.

In the datasheet, I can find 2 interfaces.

But when using the Processor Expert for iMX6UL, I can only see 1 uSDHC interface.

So what is correct?

Hello,

The Datasheet is correct - 2 uSDHC.

Have a great day,
Yuri

Hello,

See schematic page 7 SPF-28617_C1.pdf, please !
There are 2 uSDHC IPs in i.MX6ul, But SD2 signals are multiplexed with NAND Pads. So you had better refter to Reference Manual of i.MX6UL when you want to get PADs IOMUX mode.
