hi,
i'm actually trying to convert my i.mx6 boards to DM, many things are
already doing well.
But I've trouble getting the console (UART) runnin SPL.
The "preloader_console_init" is called very early in board_init_f, i guess
that DM isn't ready at this point.
has anyone experience in this?
Yes I've faced the same, look like DEBUG Uart doesn't support low
level init. Peng or someone can explain more.
When converting the OPOS6UL to DM, I had to move the
preloader_console_init call into the spl_board_init function.
thanks for this hint, i also tried this. But unfortunately without success.
But it is good to know that this way on your side works.
what i've done to try make it work:
add to my dts:
chosen {
stdout-path = &uart1;
};
&uart1 {
u-boot,dm-spl;
u-boot,dm-preloc;
status = "okay";
};
so the device should be present during spl stage and console should be
set to it.
# Serial drivers
#
CONFIG_BAUDRATE=115200
CONFIG_SERIAL_PRESENT=y
CONFIG_SPL_SERIAL_PRESENT=y
CONFIG_DM_SERIAL=y
CONFIG_SPL_DM_SERIAL=y
CONFIG_MXC_UART=y
maybe i'm still missing something.
