help?at91rm9200-ek board?test the sd card using mci interface - "jec...@ymail.com" - Aug 9 20:13:44 2009
Hi,all
I have a at91rm9200-ek board, and it doesn't have some test code,so it must write by myself.
when i tested the sd card using mci interface, i have changed the at91rm9200-dk board's testing code into at91rm9200-ek board. the code
can read the cid correctly, but it can read and write a block into
the sd card. i don't know why, because i have tested the pins of sd
card, the pins have signals.
should anybody help me ... or give the testing code to me ,plz...!
sorry about my poor English~ :-)
Regards~
