I would like to completely erase the EEPROM and then shutdown the RaspBerry Pi 4 that I bought. When you then insert a USB-stick with your own bootloader, it should search for it and automatically install the bootloader you have either compiled or downloaded, so you can run your own operating system.
I am a qualified Computer Science engineer and I need a simple workstation to build my own operating system, but the Raspberry Pi doesn't allow me to program or install anything of my own. This is a problem.
Has anyone been able to install a different OS? The processor is a RISC processor and the basic instruction set hasn't changed, it has only been expanded, so if you make use of the basic instruction set it will still work.
