This one solved our problem, including the editing of boot.cmd

Rpi4 and error -22

Dear, Fixed the issue at hand. I encountered the same issue (-22 bus width). Hardware: Rasp 4 rev 1.5 c03115 BCM 2835 boot from SD with Rasp OS, updated using APT & bootemi (although it was not necessary for me) changed the booti lines as described; Raspberry Pi 4 Model B Rev 1.5 - error -5 whilst initialising SD card - #7 by wiesel removed the file boot.scr!! Booted and worked for me!
