Hi! My Pi4 isn’t booting up again, the green light blinks 7 times.
It’s not the first time that i have this issue. I have started a couple of times with a fresh install on a USB stick, everything works well for a couple of days, and then it stop working
What could the problem be? Is my Pi4 broken?
When it blinks 7 times it can not find a valid boot drive. Maybe the USB stick is dying. Maybe you have a power issue and data gets corrupted over time, which leads also to a unbootable drive.
Can you try another stick? You can also check
dmesg for power issues and other problems.
it’s connected to an UPS, so shouldn’t be a power issue
the USB stick is less than 4 moths old, do you think it can die so quickly?
Also, i have no HDMI input
LED error code can be found there Raspberry Pi Documentation - Configuration
7 short flashed means
Kernel image not found. This indicated data corruption. Can you connect USB pen stick to your computer and check content off boot folder
Sorry, the whole USB device should be called
boot on Windows. Just check what is on the stick.
can you share content from
ok seems to be fine.
However, you could try to download latest kernel (possible on Windows) and copy it to your SD card boot partition firmware/boot at stable · raspberrypi/firmware · GitHub
In a first step try to replace the
kernel8.img file. If this is not working, add other
kernel*.img files and/or replace rest of boot partition.
kernel8.img, no more green light, can find the Pi4 on my network but can’t access it neither via dietpi dashboard or putty
does it react on
ping?? Try to connect a screen to check what happen.
ping is ok, but i have no hdmi output on both ports. Dunno if my micro hdmi is broken or the issue are the ports
you could try to add
dtoverlay=vc4-kms-v3d,noaudio to the end of
config.txt and reboot again.
HDMI is now working, i have this message
You are in emergency mode.
Give root password maintenance
can you try to replace all files on the boot partition?
even the overlays folder?
Failed to mount /boot and emergency mode again
Probably the USB stick has suffered even more damage. Was it a cheap stick?
Personally, I’m using RasPiKey as SD card replacement on all my RPI. It’s working quite will with good performance. RasPiKey: Plug and Play eMMC Module for Raspberry Pi | UUGear Ok but it has a certain price
