Raspberry Pi 4B

I have just purchased a raspberry Pi 4B 8 GB ram and even after installing v2.7 image 9 which is the only one that will boot the menu does not contain node red etc.

what’s the best way to get Venus working. Do I have to purchase another raspberry Pi 3 or something?

I am simply trying to monitor the boat batteries from home. I bought the competing epro batt monitor and gave up. Now bought victron 712 after hearing on Venus

I need node red as I have already successfully programed for the fridge door to close remotely and turn on.

Hi @Bear, I think you need to install the '-os::large' images in order to get the build with node-red.

https://www.victronenergy.com/live/venus-os:large

Then the node red option is under the Venus OS Large Features

Thanks. I do have old 9 large installed from this link. It boots but the node red etc is not available

I understand 9 was altered just to make RPi 4B work

I have tried RPi 2 versions, Large up to 16. Vers 2.7, 2.6 and 2.4 but the 9 is the only one that will even boot.

I think i am hearing it might be best to get a RPi 3.....

Thanks. I will purchase a RPi 3 today. I cant easily get a 2. Is the RPi 3B considered stable enough. Is the RAM size important for stability ?

I'm happy running v2.70~5-large-16 on my RPI 4 (2 GB) but do know some are experiencing problems with a PRI 4 not booting.

I'd try the latest image and see if it works then report back.

Hey, how did you get it working? I can boot v2.70_4-large-17 but only if i copy the latest "start4.elf" to the boot partition from here https://github.com/raspberrypi/firmware/tree/master/boot but the usb ports are not working

I didn't have to do anything special. Just flashing the image to SD card and putting it in the PI just worked.

Others, like yourself are not as lucky and no one has been able to determine why some RPI4s boot while others do not.

It's possible your USB problem is due to a version mismatch. The current Venus large RPI4 image runs Linux 4.19.81 while the files in the repo are for 5.10. But that is a guess.

If you can capture the console output during boot it might help determine why some PI4s boot and others do not.

The current version is v2.70~4-large-17

There are different versions for RPI 2/3 and RPI 4

Explained here:

https://www.victronenergy.com/live/venus-os:large

Downloads are here:

https://www.dropbox.com/sh/i8ru22o4ydws1rx/AADpa8lj5s2APZ2JS78OGPjKa?dl=0&lst=

If you are not currently running ...-large-16 or later, you need to use the image. So for the RPI4:

Flash that to an SD card. I use Raspberry PI Image (Mac OS for me but also a Windows version). Others use Etcher

See of the green LED is flashing and match it to codes here:

https://support.buyapi.ca/article/33-raspberry-pi-act-led-error-patterns

Note that document shows blink codes for different RPI models. Make sure you are looking at the list for the RPI4.


Is it possible you have a bad SD card? Try flashing a new one from the large image. You must use a flash tool. You can't simply copy files to the SD card.

I actually never installed the -17 image. I'd already upgraded to the -16 image so when -17 came out, I used the .swu file. So ....

You might try the -16 image instead.

I think i know what is the problem. My bootloader is too new , what is your bootloader version? https://media.discordapp.net/attachments/696725407021531158/827173672707948604/unknown.png

My boot loader is the same as yours but the "config" is different: 478572d5 vs a9c83900.

You have a newer board than I do: b03114 vs b03112.

I have the same amount of RAM (2 GB).

I can't compare other messages since the only way I see the same screen is if I remove the SD card.

What is the green LED flash sequence? This tells us why the PI isn't booting.
