I added BLtouch and upgrade firmware. Now it looks like BLtouch doesn't work. It doesn't do nothing when I press probe, it smashes nozzle to the heatbed.

I have uploaded firmware for Z homing.

[github.com]

Connected black and white to Z switch.

Printer is Ender 3 pro with SKR-mini-E3 board

Any idea?

I heard the 5V power supply was not stable on that board. Two options, one if you connect the USB to the board you get stable 5V or take BL Touch to a buck converter for the 5V.
