Hi, i need to setup a script to validate the raspberry hardware connected to a desktop PC, and im not sure how to go about it.

We are in an environment where we need to flash an OS + some goodies to a RPI module, and currently this is done using rpiBoot.

the current setup is:

start rpiboot - waiting for bcm...

plug in rpi over usb connection

mount the disk

configure/validate some partitioning

write our software to pi

validate

complete

Up until recently we have only worked with CM3 modules, so no need to double check the compute module type, but i want to be certain of the device hardware during this process, preferable between steps 3 and 4.

i have been doing some experiments myself, but all information online points to using feature that are not available without the raspberry actually running such as:

cat /sys/firmware/devicetree/base/model

cat /proc/cpuinfo

And looking around in the /boot folder doesn't provide me any obvious solution, since that seems to contain bcm... files for multiple version, as far as i can tell, so im not sure i can go by that somehow.

So "all" i need is a way to tell if the device mounted is a CM3, CM4, CM4S ( or CM5 in the future )

Any tips would be appreciated :)
