Note that it is perfectly fine to have the root filesystem on eMMC and U-Boot on uSD. That is my preferred configuration as it allows for easy testing of U-Boot updates since you can simply swap out uSD cards. > rkiic1 at mainbus0 > iic1 at rkiic1 > "haoyu,hym8563" at iic1 addr 0x51 not configured So that's your RTC. Judging from the data sheet, this is a PCF8563 clone. Can you try the attached diff? > rkiic3 at mainbus0 > iic3 at rkiic3 > "rockchip,rk809" at iic3 addr 0x20 not configured So this board uses a different PMIC than the "classic" RK3399 boards. Judging from the datasheet there are some significant differences, so this isn't a matter of just adding a compatible string to the rkpmic(4) driver. But the hardware is probably similar enough to extend that driver instead of adding a new one. This would probably get rid of: > cpu0: regulator not implemented and provide proper DVFS support on this board which will make the CPU run at higher clock speeds.
