MLO not detecting MMC card with SDK2.0

Hi


I am developing application on my custom board which is base on ti am43xx_evm type.


Earlier I use to work with TISDK7 ( am437x-evm-sdk-src-07.01.00.00.tar.gz) but now we want to port our BSP base on latest SDK ( ti-processor-sdk-linux-rt-am437x-evm-02.00.01.07).

I am currently facing problem in porting uboot and my observation are as below.

1) In my board MMC card is on Port 1 so we have done pin mux related changes accordingly

2) After changes I have found MLO is not able to detect MMC it is stuck on API (mmc_initialize) as no MMC device detected.

3) In order to verify my u-boot.img ( base on SDK02.00) working I have used prebuilt MLO image ( Base on SDK7) and I have found u-boot.img is working without any problem but still I am not able to find out the root cause of why MLO is not detecting MMC card.

Please help me in this port activity.

Regards

Nishith
