UConsole has no life :( Please Help

uConsole
1

I received my UConsole today.

I put everything together very carefully.

I flashed Rex’s image onto a Sandisk 256gb card.

Nothing works.

I tried the CM5 eMMC version. It doesn’t work nor does the Lite.

I took everything apart and put it all back together again even more carefully.

I’ve used 3 different types of cards so far. 256, 256 and 32.

The 32gb card is still in there and I’m hoping it boots or does anything… something.

I’m now even trying to boot / power up without the audio module.

Still no life. No boot screen. No backlights on the screen or keyboard.

Someone please help. I feel so let down.

have you tried to start from usb-c power? seems like your battery module is not inserted properly: Bookworm 6.12.y for the uConsole and DevTerm - #362 by Rex

Do those 8 pins need to go fully inside?

Hm, I see your concussion, please follow this instruction:

Thank you for that.

Battery pins are now in place properly.

I did a fresh flash and powered on with inserted batteries and power cable.

I can feel heat coming off the CM5 but still no life.

check this topic, there are multiple instances when rex helped to boot both EMMC and Lite versions

I can’t even do that at the moment. My waveshare mini base board just keeps flashing 4 times and cutting out.

I think I’ve knackered it?

Can I edit the config.txt file on the card with the edits below?

[all]

BOOT_UART=1

# Switch off PMIC outputs on HALT

POWER_OFF_ON_HALT=1

# Try boot on SDCard repeatly

BOOT_ORDER=0xf1

SD_BOOT_MAX_RETRIES=2

# Slow down SDCard SDR Mode on bootloader

SD_QUIRKS=1

That edit you did right there is for the EEPROM not for the config.txt

What did you use to flash the image? If you used raspi imager then make sure you don’t apply any custom settings. With the emmc model you can’t use the SD card so make sure to flash the emmc on that other carrier board.

I’ve not made any edits yet to anything.

I used the official Raspberry Pi imager to flash the card with your image - 6.12

I even tried the eMMC version using boot mode which seems to work fine on the Waveshare board and shows the eMMC CM5 as an external drive. Not working.

For the lite, I’ve tried 3 different cards but still no life.

I don’t know what to do.

11

when flashing the image did you make sure not to apply any custom settings?

the lite version does need the eeprom edited to fully work right. boot the cm5 lite on that carrier board and apply the eeprom changes as outlined in my bookworm post. then try it again in the uconsole.

Yes I ensured no customer settings were applied when flashing.

When trying to boot using the Waveshare board, it gives me 4 green lights and cuts out. This repeats constantly. I think I’ve messed something up on that board?

13

try and flash an official RPi image and try that board again. make sure the CM5 is really snapped in good.

I flashed the official image on a card. I’m using the correct power supply.

The CM5 is snapped in properly.

But the base board just keeps flashing green 4 times then cutting out.

have you tried it without that riser board?

what about the emmc cm5 have you got that to boot in that carrier board?

I just flashed the CM5 eMMC with the official Pi OS.

I’m not using the riser board.

I’m now trying to boot it up but still getting flashing 4 green lights repeating constantly.

  • 4 Blinks:

    The 4-blink pattern on a Raspberry Pi CM5 usually signifies that the system cannot locate or load the start.elf file, which is essential for booting the operating system.

seems like you are flashing it wrong.

I get the same when I use the CM5 Lite and flash the card.

Flashing is done correctly using MacOS and terminal.

The CM5 eMMC is shown as an external drive then I use Pi imager.

19

By the way, I’m getting 4 green flashing lights on the Waveshare mini base board. Not any of the CM5.

20

Out of curiosity, does the Waveshare board LED also blink 4 times when you power it on without the CM5 installed?

If not, the flashing LED may be a function of the CM5 itself. I found this page which lists the raspberry pi LED error codes: https://www.raspberrypi.com/documentation/computers/configuration.html#led-warning-flash-codes which might be useful.
