RPI4 Long Black Screen on boot from SSD
Zhiesold last edited by
I finally managed to get my RPI4 booting from a SSD via USB and everything works fine but the boot time is insanely long.
It just shows the Bootloader Screen first, then it goes to a black Screen for at least 3 minutes and then shows the Splash-Screen or the "creating share" Screen depending on if its the first boot after burning the Image or not.
I already tried downloading and burning the latest Image multiple times but its the same every time.
There are no ROM's loaded onto the SSD other than the ones that came pre-installed and booting from a microSD card works flawlessly.
If you have any Ideas, Help would be greatly appreciated!
@Zhiesold From what I saw here on the forum, the users who reported this type of problem are those who are using a Nespi4case, it seems that there is a power problem, see these posts:

@Zing Thanks for the reply but I think I managed to got it to work now.
I installed the newest stable bootloader instead of a beta one which made the pi boot fast in 50% of the boots, then I set the console parameter in the cmdline.txt to tty1 to see if I can notice a pattern and saw that there is some error with the /dev directory ("udevadm settle failed") every time it boots slow and that the SSD is already in use by another process or something like that.
Next I disabled WIFI and Updates and removed the "fastboot" parameter from the "cmdline.txt" and now it's working.
So I'm not sure if it was the bootloader or the fastboot or a combination of everything but it boots in roughly 20 seconds now.
I'm not using a case and my power supply is the official one for the pi4 btw.
@Zhiesold Okay, thanks for the feedback, this information may help other people!
