Part Number: AM5708
Other Parts Discussed in Thread: DRA722, DRA718, DRA71
Hi,
I'm trying to boot Linux kernel from SD-card. This board based on AM5708. But system stop at "Waiting for root device PARTUUID="
I use ti-processor-sdk-linux-am57xx-evm-06.01.00.08. U-Boot is more new.

In kernel building a lot of settings were tried but it wasn't have any results. When using TI's AM572X-EVM kernel booting was finished but with a lot of errors, though u-boot and dtb are the same.
If we comments below lines
/* pinctrl-0 = <&mmc1_pins_default_no_clk_pu>;
pinctrl-1 = <&mmc1_pins_hs>; */
in case of my kernel mmc driver doesn't print this error "no pinctrl state for default mode". In case TI's AM572X-EVM kernel boot this message appears and loading stopped also at "Waiting for root device PARTUUID=". It seems that mmc driver doesn't load, am I right?
Please help resolve this problem
Regards Andrei
