IMX6ULL custom board not boot

My imx6ull board is currently experiencing this situation. Before that it was possible to load u-boot from sd card. Can someone help me?

Hello all,

We have exactly the same issue. No responses from NXP yet?

We are looking into our schematics, and comparing with the EVK.

Our main disadvantage here is that we are using a different PHY chip (KSZ8081RNA instead of KSZ8081RNB)
