KwikStik SDHC issue

Hi everyone,

 

I'm trying to use a SD card on the kwikStik kit (K40x256).  I realized that SD card connector's data pins (DATA0~DATA3) are connected to SDHC0_D4~SDHC0_D7 while that pins are unused in 4 bits mode. So we cannot use SDHC support. So i tried to use the SD card trough SPI. However, SD card pin connections do not support SPI either.

 

This is really true? Freescale put a SD card slot connected to pins that we can not use?

Unfortunately yes, you cannot use the SD Card slot in the current version of KwikStik's. It will be fixed on future versions.

 

See the KwikStik errata document here: http://cache.freescale.com/files/32bit/doc/errata/KWIKSTIKK40HWER.pdf
