Advanced users • Booting RASPI4 / CM4 from external SPI Flash

Hi,

is there a chance to boot Raspi4/CM4 with a minimal initramfs (RootFS, Kernel just few MB) from external SPI flash? Just as kind of rescue service.
I know interfaces such as USB, PXE, PCIe, SD-CARD, eMMC are by default available.

Thanks for feedback,
Piwi
