Hi Simon,

I am playing with SPL for U-Boot with DM serial driver for OF_CONTROL and without. Can you please tell me what's the status on SPL in connection to DM?
Definitely it is not just about enabling it via Kconfig.

Thanks,
Michal

It's in very early stages. The rockchip series uses it and I believe Marek is using it for socfpga.

You will need to add u-boot,dm-pre-reloc to your console node that that the DT has that node. See u-boot-dm/rockchip-working for what happens there. Use fdtdump on your u-boot-spl.dtb to check that it has what is needed.

Also, enabling DEBUG_UART is a good idea.

Regards,
Simon
