I create a custom board base on rock pi s, using rk3308 and boot from eMMC (klm4g1fepd-b031-samsung)
When i config vqmmc with 3.3v, board still work perfect, but when a change device tree and HW using 1.8v, get error as below. Can help me fix that?. Thanks!
device-tree eMMC config
bus-width = <8>;
num-slots = <1>;
status = “okay”;
