Booting from HDD (obviously) did not work.17:000008b0
When I think about it, it is no surprise that it did not work. PI4 is using entirely different chip comparing to PI3 so it was too optimistic (if not plain stupid) that I expected that it'll behave the same way.
Which brings me to ask: does the PI4 have ability to boot from device other than SD card at all? If it does - how we use it?
Kind regards, Vladimir
