Hi ,


 


I have succesfully setup the sdram controller to work on the lpc4357 evb from element14. Now i'm trying to get the sdio at work.


The clk for the sdcard is sfclk2. But on this forum I read that all 4 emc clocks are needed for the sdram. And indeed if I use 1 or more clocks for something else like the sdram , then my memory test fails.


So my question , how do you use sdram and sdio at the same time , if all 4 clocks seem to be needed for emc ?


Hoping someone can help me on this
