Pi 4 can't boot from USB

Wed Jul 03, 2019 4:42 pm

HI, I've tried writing both a USB stick and a USB HDD from NOOBS and when I try to boot from it without an SD card in the slot, it just sits with the green light flashing 4 times.
I've checked the sticky (for some reason it says it was updated in 3 weeks time on 26th July!)
No idea what else to try.
Any ideas?

The Pi4 can't currently boot from USB. It's on the todo list but it's not quite ready yet.

you can still use USB drives for your rootfs if you have an sd card with the /boot files on it and do a little editing of the cmdline.txt file
