Hi I’m trying to install sat nogs on a new raspberry pi 4.
I have tryied looking at all the wiki’s, looking at poeples posts & getting no where. I have also down loaded a number of img’s & these didn’t work. The image is what I get at start up.
I don’t have access to linux, so what ever I do needs to be windows based 
Help please as I leave this site in 24hrs.

Hello @vk2pet
Can you please let us know which steps have you followed and what fails from here?
https://wiki.satnogs.org/Raspberry_Pi
Hi,
Back ground, I have 2 Raspberry pi4 that are doing the same thing.If I put a normal raspberry pi image onto the SD card, it works for both machines. So it’s software related issues.
Steps I have done,
Thanks
Pete

Hi Pete,
Lets see if we can give you some information so you will be able to get further.
I will try to also support your operating system challenge.
The following program can be used to check the file integrity.
Unzip the downloaded artifacts.zip file, this will give you the following directory structure:
.\artifacts\deploy
Now you can check the two files if you like with the above program.
Now unzip the image_2020-12-27-Raspbian-SatNOGS-lite.zip and use the output file 2020-12-27-Raspbian-SatNOGS-lite.img as input for Balena Etcher.
When this is done try to boot from the SD card you just created.
Hi!
The error message in the first image reads:
start4.elf: is not compatible
This board requires newer software
According to this thread the firmware of your Rasperry Pi 4 is not backward-compatible to the image on the sd card, so that it can’t be booted.
An image with updated firmware&kernel is needed. Unfortunately we do not have such an updated image yet. So, until we were able to provide an updated SatNOGS RaspbianOS Image, I am afraid to tell you that it’ not possible to easily use this Raspberry Pi for SatNOGS.
Of course, a manual installation of all the SatNOGS tools onto a base Raspbian Image would work, but is a quite complicated endeavor.
@Acinonyx @fredy : Please have a look here too. ^
Sincerely,
Fabian
Ok, it might be possible to update the image_2020-12-27-Raspbian-SatNOGS-lite.zip image manually, by following this comment.
I can’t test this (no RPi 4 here), but those would be the steps:
Dowload the following files:
Mout the SD card with your PC and copy the downloaded files into the boot partition on the SD card (there will already be older versions of some or all of the files on the card, overwrite them).
Retry booting the Raspberry Pi with the modified SD card.
I just installed a Pi 4 and had the exact same problem when I burned from a W 10 machine. I reburned a few times with different SD and got the same result. However, I burned from my Ubuntu machine, and it worked with no problem.
Thanks for information @kerel
Lets see if I can mount the image on a loop device and add the files to the image.
I will let you know if I was successful and if so, share the updated image.
Fingers crossed
We are getting somewhere.

Check the files and umount the image.
Zip the image and copy it to a location that you can use to give this a try.
The new image can be download ~for a limited time~ via the following link
Please let me know if you where successful so I can remove the file, otherwise there is a chance my ISP will block my IP access due to using to much uplink bandwidth.
The file is now shared on a more permanent location.
Thanks for your help.
Update: router had an issue on that previous pic, now I’m in.
You will see 2 new satnogs in Western Australia, on a very quite site.
Thanks everyone.

Hi everyone,
I would like to thank everyone who put suggestions in & to PE0SAT who rebuilt the install software. The last issue was on my end with the network I using.
The site is a fully remote site, hence I’m now heading home on the aircraft as I write this. This is very quite in the SNR. Looking forward to some great results from that site.
Again thanks heaps tho everyone.
