Why do you need to load fitImage via SDP btw ?
Let's suppose a i.MX6 board that boots from eMMC is bricked and we need to load a new U-Boot to repair it.
imx_usb_loader is a very convenient tool to achieve this.
I have been following this thread, because I have been working through attempting to migrate the imx6q_logic board to SPL_OF_CONTROL which requires SPL_DM.
To working around the issue you're describing, I played with disabling SPL_DM_USB. With that removed, I can still use nearly all the benefits of SPL_DM without losing access to imx_usb_loader. See log:

Having said that, I haven't posted all my updates yet, because I am working on MMC start issues between MMC1 and MMC2. If you'd like to see some patches, etc. I can share them with you.

This method has been working well for a long time, but after DM transition we can no longer load and run SPL + u-boot-dtb.img via SDP. _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de https://lists.denx.de/listinfo/u-boot
