board not boot


I comment ‘uenvcmd’ variable in the file /boot/uboot/uEnv.txt of eMMc and now the board not boot (the D5 led not light, other LED lights are on)

What can I do?

Boot via microSD, mount the eMMC and "un-comment" uenvcmd...


I’ve also been trying to boot via microSD but not work. I hold the boot button (S2) and while holding the button I insert the power but not work. Only the power light flash.

I don’t know what else I can try.
