I am working on a new PCB design in which we need to mount a RPi CM4 on 100-pin connectors.
There will be 10+ PCBs in our project and on each PCB we will have a RPi CM4 having web client implemented. All the boards need to be connected to a network switch or router through RJ45 connectors on the PCBs. The Windows PC will also be connected to the same switch or router and will have web server to communicate to the PCBs having RPi CM4.
I already have added SD Card connector in the PCB design and route to the SD Card pins available on 100-pin connectors of RPi CM4.
We don't have any space for USB connector on the PCB.
I am not sure how do we program the Flash available on RPi CM4, such that every time upon power reset it load the OS from Flash and not through SD Card.
