ALL-H3-CC does not detect emmc 5.x

I booted into Raspbian 11 on the ALL-H3-CC, after installing the 5.x 128GB card. The emmc module is not being picked up by the kernel, even though it’s running 6.1. Documentation for emmc on ALL-H3-CC is pretty hard to find, so asking “what am I missing?” here.

Hi.

Looking at the product page, it seems you need eMMC 4.x for the Allwinner boards.

Storage: MicroSD Card Slot
eMMC 4.x Interface

Yeah, that seems to checkout. I moved the same 128GB 5.x emmc into a Le Potato, and it was picked up immediately after boot.
