Issue in booting from SD card

[rineet_kv]

Hi,

We are using IMX 6UL with boot device as SD card. Getting following error.

Same SD card is working with the EVK board. I have pasted the logs below.

Hi Rineet

SD card which is working with the EVK board has ddr settings for EVK board,

which may not work on custom board. Uboot for custom board should be rebuilt

with new ddr calibration settings found from ddr test, put them in uboot/../mx6ul_14x14_evk/imximage.cfg
