Hi ,
ISSUE : SDCARD driver porting problem
PROCESSOR : IMX27
PLATFORM : ADS BOARD
CONTROLLER : INBUILT IMX 27 SDHC controller
I am upgrading the linux from 2.6.19 to 2.6.25
linux kernel is up and mounting the file system properly.
Now i am attaching the drivers. There is no problem in porting the drivers ( lcd / touch screeen)
while porting the sdcard driver i am getting the error. please find the below log. I am using freescale IMX27 Processor - SDHC controller in built.
CMD FLOW SEEMS CORRECT. i will be happy if some one help us to go forward.
