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.</P><P>&nbsp;</P><P>This is really true? Freescale put a SD card slot connected to pins that we can not use?</P><P>&nbsp;</P></BODY></HTML> Thu, 09 Jun 2011 00:58:30 GMT gustavod 2011-06-09T00:58:30Z KwikStik SDHC issue https://community.nxp.com/t5/Kinetis-Microcontrollers/KwikStik-SDHC-issue/m-p/213111#M3577 <HTML><HEAD></HEAD><BODY><P>Hi everyone,</P><P>&nbsp;</P><P>I'm trying to use a SD card on the kwikStik kit (K40x256). &nbsp;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.

It will be fixed on future versions.</P><P>&nbsp;</P><P>See the KwikStik errata document here: <A href="http://cache.freescale.com/files/32bit/doc/errata/KWIKSTIKK40HWER.pdf" rel="nofollow" target="_self">http://cache.freescale.com/files/32bit/doc/errata/KWIKSTIKK40HWER.pdf</A></P><P>&nbsp;</P><P>&nbsp;</P></BODY></HTML> Thu, 09 Jun 2011 02:31:28 GMT https://community.nxp.com/t5/Kinetis-Microcontrollers/KwikStik-SDHC-issue/m-p/213112#M3578 anthony_huereca 2011-06-09T02:31:28Z
