We recently received our custom board with the i.MX6ULL processor.
It's fairly similar to the EVK, however, one ethernet PHY has been omitted and an eMMC is used instead of the SD card.
Unfortunately, I am having some trouble bringing up the board.
I tried using uuu with the provided sample images.
sudo ./uuu uuu.auto-imx6ull14x14evk
uuu (Universal Update Utility) for nxp imx chips -- libuuu_1.4.107-15-gd1c466c

It repeats this loop every couple seconds.
Does this mean that not finding the PHY is blocking the next step ?
Any help is appreciated !
