eMMC not booting in imx6UL

[obulesu_veggidi]

Hi,

With Our custom imx6UL board I am able to boot from SD card, and I flashed/copied the images to emmc(mmcblk1). But I am not able to boot the device from eMMC. Device is loading with u-boot and throwing following error.

Hi obulesu_veggidi

for "Card did not respond to voltage select!" error one can look hints on

https://community.nxp.com/t5/i-MX-Processors/iMX6q-Sabre-lite-board-Card-did-not-respond-to-voltage-...

also one can try "mx6ul_14x14_evk" instead "MX6UL 14X14 DDR3 ARM2"
