Hi Andrew, Sorry for the delayed reply.

Can anyone assist please? Is this the eMMC that's built into the SoM or is it external on a carrier board? Can you provide more details. On the RPi5 the uSD slot is using the SoC built in controller, I presume that's the case on the CM5 or whatever you're using as the RP1 needs to be bought up first. We don't currently support the RP1 in U-Boot so I'm not sure that's coming into play, I suspect purely the SDHCI controllers. Unfortunately the details of most of the broadcom chips are closed and even the RPi U-Boot maintainers don't have access to those so we might be at a bit of a loss ATM.
