I'm designing a custom board with an iMX28 processor. I also have an iMX28EVK board to make some test.
I boot on SD card with the 2 card.
Result on EVK board :
- the SD card is detected
- the card boot correctly
Result on custom board :
- no boot
- error on debug UART 0x8020A014 (this error means that there is a problem with SD detection)
On the iMX28 website there is an information about a patch to correct the SSP_SCK polarity. Then I have 2 questions :
- was this patch apply by freescale on the EVK board ?
- I don't apply this patch on my board, is it the reason of my problem ?
