Please find following repository with DM/DTS conversion for TPC70 imx6q board (it also has SPL DM conversion working - board boots from SD card and eMMC): https://github.com/lmajewski/u-boot-dfu/commits/DM-SPL-TPC70 My guess is that you need the pinctrl DM support in SPL, to make the card detect pin working. &pinctrl_usdhc4 { u-boot,dm-spl; }; &pinctrl_usdhc2 { u-boot,dm-spl; }; &gpio2 { u-boot,dm-spl; }; And also the pinctrl-imx6q.c fix to: static struct imx_pinctrl_soc_info imx6_pinctrl_soc_info __section(".data"); To sum up: TPC70 (imx6q) has support for DM/DTS in both SPL and u-boot proper. The issue with this port is that it uses Common Clock Framework from Linux and would need SPL's OF_PLATDATA support in eMMC and uart drivers to reduce SPL size.
