imx6ul booting from emmc

When using MFGtools to program, there is no error, and the serial port can output normally. When booting from eMMC after successful burning, the serial port does not have any printing information.

do you use nxp imx6ul evk board？ on the imx6ul evk board, the emmc is unpopulated, pls check it, how do you program the image to the emmc? and what vbs file do you use?if you use emmc on sd2, pls check if you set ucl.xml correct or not. when you booting, pls check if you set boot mode on the board correct or not(sw601 and SW602)

your information too limited to confim, I don't know what your change on SW or HW, that's why I asked some questions, since you still don't offer more detailed information, I just can suggest that you can use the patch as below, hope helpful for you

the flag needs to active to enable whole 8bit data pin of eMMC:
