rpi64 recipe for RaspberryPi Compute Module 4

[obachtos]

I'm would to use debos to build an image for a Raspberry Pi Compute Module 4. When I naively just use the rpi64 recipe the system fails to boot properly. u-boot starts with the following:

U-Boot 2021.01+dfsg-4 (Mar 12 2021 - 23:00:43 +0000)

So apparently the eMMC memory is not detected properly. Also when I do mmc info I get 0 Bytes capacity:

U-Boot> mmc info
Device: emmc2@7e340000
Manufacturer ID: 15
OEM: 100

MMC version 4.0
High Capacity: Yes

Bus Width: 4-bit
Erase Group Size: 104 MiB

Any suggestions on how I could adapt the recipe to work for a CM4?

Hi @obachtos

Did you eventually get this to work?
I'm trying to build a Debos image for CM4 and stumbling upon the same problems

Thanks!

Unfortunately no, we ended up building an image by hand.

Ok thank you for the info!
