I just added a Skr mini E3 V3.0 as a seecond mcu in klipper connected via usb to my rpi 4b

Everything works fine until i restart the machine and it wont let boot the rpi, if I disconnect it it boots and then I can connect the ups port and make it work but seems like the skr is affecting the rpi boot up

i have some problem.

Remove the sd (or leave it inside) , what i finally ended doing is start with mcu off and turn them on later with a relay when rpi starts, but if you take out or in the sd it also works, dont remeber in wich state happened
