... although what I found earlier was different. I typed the model name
from DTS "Milk-V Mars CM Lite" and it gave me this:

https://milkv.io/mars-cm
which misses the "Lite" suffix.

What you pasted is called "Mini Base Board (A) Designed for Raspberry Pi
Compute Module 4" and it also does not have "Lite" in the name and
picture does not have the SoM.

I am confused now and I do not know what the DTS "Milk-V Mars CM Lite"
is. Answering to this is crucial, because it determines whether this
particular deviec has broken-cd or not.

Arguments that something else has broken-cd, thus you add such property
to "Milk-V Mars CM Lite" are obviously wrong.




Best regards,
Krzysztof
