Hi Jaap, Actually I'm able to use SDP on imx8mm_evk over SPL. You need to apply the following patchset:
https://patchwork.ozlabs.org/project/uboot/list/?series=251796&state=*
plus you need the following configs:
CONFIG_SPL_USB_HOST=y CONFIG_SDP_LOADADDR=0x40400000
All described here:

I share with you also all config that I use on U-Boot 2022-04-rc4:
CONFIG_SPL_USB_HOST=y CONFIG_SPL_USB_HOST_SUPPORT=y CONFIG_SPL_USB_GADGET=y CONFIG_SPL_USB_SDP_SUPPORT=y CONFIG_CMD_USB=y CONFIG_CMD_USB_SDP=y CONFIG_CMD_USB_MASS_STORAGE=y CONFIG_POWER_DOMAIN=y CONFIG_IMX8M_POWER_DOMAIN=y CONFIG_USB=y CONFIG_DM_USB=y # CONFIG_SPL_DM_USB is not set CONFIG_USB_EHCI_HCD=y CONFIG_MXC_USB_OTG_HACTIVE=y CONFIG_USB_GADGET=y CONFIG_USB_GADGET_MANUFACTURER="FSL" CONFIG_USB_GADGET_VENDOR_NUM=0x0525 CONFIG_USB_GADGET_PRODUCT_NUM=0xa4a5 CONFIG_CI_UDC=y CONFIG_USB_GADGET_DOWNLOAD=y CONFIG_SDP_LOADADDR=0x40400000
Thank you. I will give this another try, but I still assume imx8mq_evk != imx8mm_evk and it seems imx8mm is having code which imx8mq does not have (board/spl). Once I have done more research I will report back.
greetings,
Jaap
