Hi Heiko,

Can anyone confirm the behavior?
imx8mn ddr4 evk prints the SPL part just fine.
Take a look at arch/arm/dts/imx8mn-ddr4-evk-u-boot.dtsi .
It passes:
&uart2 {
u-boot,dm-spl;
};
&pinctrl_uart2 {
u-boot,dm-spl;
};
Are you doing the same for the imx8mn ddr3 u-boot dtsi?
Indeed these are missing. Now I see the whole output from U-Boot but
the output from SPL is still missing. When enabloing SPL_DM_SERIAL the
board does not start.
I now did include the whole "imx8mn-ddr4-evk-u-boot.dtsi" like it is
done in "imx8mn-evk-u-boot.dtsi". Then it works.
make sure preload_console_init is called after spl_early_init or
spl_init, not before.
Regards,
Peng.
