Hello Hal,
I have seen
Milk-V Mars CM: MARC-V10-2340-D004E016-xxxxxxxx Milk-V Mars CM lite: MARC-V10-2340-D002E016-xxxxxxxx
Obviously here they got the eMMC size wrong. Milk-V should have used E000 for the lite version. But at least they provide a correction procedure in https://milkv.io/docs/mars/compute-module/update-eeprom and confirm the usage of the values MARC and E###.
So here we should be able to detect these two boards, too.
