no boot, no display tried all recommended from pi sticky threads and utube vids,
January 31, 2024, 11:25
Tried two different sd cards, formatted in cmd , used imager, etcher, different laptops, only thing I haven’t tried is another official psu, I only have the one or iPad cable, tried that same thing, no display, had 8 green flash’s then did sd boot effortm, now power on two lil flashes then solid green n nothing displayed
ok first whats your power supply like?
Standard psu from kit
This pi was working, it is like 5 year old
that could do it
pi4?
You need to connect a display to investigate the issue
Thats electronics, it works and then it doesn't work.
ok so itd be a lot easier if you have a display. so maybe you could lend one? use one from school/work this is infact @oops.se so not to take his credit
we both highly suggest that
Different hdmi?
Can you confirm the blink pattern seems fine? Like I mentioned tinned before it was the 8 blinks, I reflashed it multiple times and now it does what my video shows
1. i need to know the pi model to discuss the led blinks 2. a solid green is very difficult to troubleshoot without a display 3. depending on the pi model it can be either micro hdmi or hdmi
Rpi4 b
Do you have a display connected to the Raspberry Pi?
The video is to short!
Had hdmi connected, no nothing,
I’ll upload the whole process when I get home
Currently, no display, and unsure if it is booting, maybe I try lite os again and try ssh
ok
You should get video output on HDMI0, that where the boot messages is ddisplayed
If you don't get any video output at all it is probably a broken Pi
very likely if it's 5 years old
I have 10years+ that still runs. It can be so many factors.
wow.
Hmmmm
I am going to try to find another hdmi cord to try gotta find it first…put it in a spot I’d wouldn’t forget…….
In port 1
No hdmi connected
No sd card
Gave@pi to my buddy to try with different cables and psu cable, same result, he took same sd it boots no issue in another pi, when same sd is used on this pi 8 flashes
>>> Long flashes Short flashes Status
0 3 Generic failure to boot
0 4 start*.elf not found
0 7 Kernel image not found
0 8 SDRAM failure
0 9 Insufficient SDRAM
0 10 In HALT state
2 1 Partition not FAT
2 2 Failed to read from partition
2 3 Extended partition not FAT
2 4 File signature/hash mismatch - Pi 4
4 4 Unsupported board type
4 5 Fatal firmware error
4 6 Power failure type A
4 7 Power failure type B
so:
if the ACT LED blinks in a regular four blink pattern, it cannot find bootcode (start.elf).
if the ACT LED blinks in an irregular pattern, then booting has started.
If the ACT LED doesn't blink, then the EEPROM code might be corrupted. Try again without anything connected to make sure.
Yep I know that website…. That’s y I’m here
Buddy is gonna try reflo
Otherwise rip pi
