Hello ,

     I'm leanring the imx6ulevk and using the L4.14.98ga. I wanted to burn the u-boot and rootfs.sdcard into eMMC, but it failed. I don't how deal with it. I used the uuu according to the reference -- i.MX Linux User's Guide. 

 

① The serial download mode is as follows:

SW601       ON    OFF

SW602       ON    OFF   OFF   OFF

② When I plug in the USB port, it would show the choose of accessing ubuntu. But when I used uuu to burn, the hint showed again.

the hint showed again

③ The Ubuntu interface is shown below:
