I would like to use nRPIBOOT on a CM5 after boot. Information is at best confusing:
- in the CM5 datasheet section C (https://datasheets.raspberrypi.com/cm5/ ... asheet.pdf), it's written that there is a PINOUT change for #93 but there is no different information. It's confusing.
- at https://github.com/raspberrypi/usbboot/ ... e-module-4, it says "On Compute Module 5 EMMC-DISABLE / nRPIBOOT (BCM2712 GPIO 20)". But GPIO 20 is already on PIN 27 of the header. There is something confusing here. Are pins 27 and 93 linked together? I doubt that.
I have tried to add a button overlay for both gpio-20 and gpio-40 but pressing the button on pin 93 doesn't trigger anything. The overlay is working because I have some other buttons on that overlay. Worse, when I press the button on pin 93, the CM5 shuts down.
How do I use nRPIBOOT as a button once it has booted and on which gpio is it for CM5?
