Raspberry Pi 5 won’t start

Fri Dec 08, 2023 9:15 am

Hi Community,

I can’t get my new raspberry pi 5 to start.

It just blink 8 times green what would indicate that there is something wrong with the sdram.

I tried several PSU’s but no luck.
Ugreen nexode 100W
Anker 523 neo 47W
Steam deck PSU
Nintendo Switch PSU

And so on. I ordered the original 27W PSU now but I can’t imagine that this would change anything.

I also tried to flash different sd cards
Samsung Pro Plus 512GB
Sundisk ultra 32GB

With the official raspberry imager.

Do you guys have any idea what I could try to get it boot up?
I want finally play with it around 🥲
It’s not my first raspberry

Please can you try using the Raspberry Pi Imager to do a factory reset on the bootloader flash.

See https://www.raspberrypi.com/documentati ... tml#imager

I prepeared a sd card with the raspberry pi imager v1.8.1 with the image “sd card boot” for the raspberry pi 5. On windows 11

When I boot up the raspberry with this sd card it has constant red light and flashes 8 times green.
I got no video signal from the raspberry pi 5. So I couldn’t check if I get a green or red screen. I waited for 15 minutes before I tried to restarted the pie with the OS sd card.

Again it just flashes green for 8 times, pause, flashes again green 8 times(and so on). No video signal.

So I restarted the raspberry again but plugged in the Ethernet port.
My router didn’t recognise the Pi in the network.

I guess I will wait till the officials PSU arrives and try again.

if you hold the power button, and then connect the usb-c port to a linux machine, this pops up in "dmesg -w":

Code: Select all

[459695.699990] usb 1-12.1: new high-speed USB device number 30 using xhci_hcd
[459695.777509] usb 1-12.1: New USB device found, idVendor=0a5c, idProduct=2712, bcdDevice= 0.00

this confirms that the SoC and basic power regulator stuff is still alive

@timg236, is the eeprom involved in that at all, or is this holding some gpio that blocks SPI booting, and forces it into rpiboot mode?

I tried it with my steam deck. USB c to usb c
So the pi is broken?
I thought it get tested before they send it out

Update:
I got now the official PSU.
Sadly the raspberry has the same faulty behaviour

I'm encountering this on my RP5 using a 5v3a charger, I think they have faulty USB-C power circuits.

I say this because I have a Geekworm X708 UPS HAT which supplies voltage directly to the 5v pin instead and I can get it to boot if powered through the hat. Though there are still other weird issues like HDMI going out when keyboard is plugged in, until you unplug the hdmi and plug it back in and chrome causing user logouts when closed via close button (but not when alt-f4ing)

The initial RPIBOOT code is handled entirely by the boot ROM by sensing the power button GPIO which is equivalent to nRPIBOOT on CM4, although electrically more complicated.

The rpiboot repo (https://github.com/raspberrypi/usbboot) now supports the Linux mass-storage-gadget and recovery.bin EEPROM flashing modes.

N.B. The old VPU mass-storage gadget FW won't be ported to BCM2712.
