Hi everyone,
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
&emmc {
bus-width = <8>;
cap-mmc-highspeed;
mmc-ddr-1_8v;
supports-emmc;
disable-wp;
non-removable;
num-slots = <1>;
status = “okay”;
};
