Accessing SDIO pins in MCIMX28EVKJ: i.MX28 Evaluation Kit

[ganeshh]

Hi,

I am planning to buy MCIMX28EVKJ: i.MX28 Evaluation Kit. in hardware schematics SDIO pins are shown but in evaluation kit no headers are given so is it just the sd card slot or pins available . i want to interface a wifi module so sdio pins are needed.

Hi Ganesh, i.MX28 EVK schematic p.8 shows

SD interface. SDIO interface uses the same pins, i.MX28

has SSP module and it is used for both SD/SDIO.

Actually there is no difference between SD and SDIO signals.
