Hi Amit,

Thank you for quick revert,

But in that PH4 pin is used for Chip Select.(Can we use any GPIO for Chip select of uSD card?)

As we can use uSD on SDIO interface of AM335x, same way, If we have Card Detect mechanism in uSD connector's mechanical pin, then how to use it for SSI interface?

Awaiting for your revert.

With regards,

Hello Jay

TM4C devices do not have a SDIO module like AM335x. You would have to use a GPIO in input mode to create a card detect
