rpi34_kerberossdr_image_18022020.zip pi4 image needs update

[CarlFK]

rpi34_kerberossdr_image_18022020.zip (which came from a drive.google link, somewhere around here...

needs it's /boot files updated: add to config.txt, hookup a serial contole:

Is this not just because you have an older batch of Pi4 and have never updated the firmware on it?

start4.elf: is not compatible
This board requires newer software

this error is reporting that start4.elf on the boot media is too old

you need to get the latest start4.elf + fixup4.dat from https://github.com/raspberrypi/firmware/tree/master/boot

"your start4.elf likely lacks support for 8gig of ram" (I recall seeing some image does not work with 8gig pi, so maybe this fixes that too.)

git clone --depth 1 --filter=blob:none https://github.com/raspberrypi/firmware (it's a big repo. If someone can tell me how to only get the /boot/ dir, that would b

rsync -rtvP firmware/boot/ /media/carl/boot

And it boots to the desktop now.

updating kernel.img can cause more issues, because then your /lib/modules is out of sync, and loadable modules stop working

thats why its recommended to only update the 2 files that are causing the issue

[krakenrf]

Ah right, this was my confusion, you are attempting to load a much older KerberosSDR image. Is there any reason that you need this image instead of the new software? The new software is also compatible with KerberosSDR hardware.

[CarlFK]

a few days ago I was clicking around trying to figure out what software to use, and it was the first thing I found.

I tried to find the page that linked to it, can't find it now. All I can remember about it was the page had something like: "doesn't work on 8gig pi4, hopefully the raspios people fix this."

[krakenrf]

Are you running a KrakenSDR or KerberosSDR?

When we first started the Kerberos image Raspberry Pi OS had a bug that meant 8GB Pi's were not compatible unless you installed everything from scratch. Pi Foundation finally fixed that and the new KrakenSDR images don't have this issue.

[CarlFK]

issue title updated ;)

I wish I could tell you how I found rpi34_kerberossdr_image_18022020.zip

I now understand it is outdated, so all that is left is to find it and remove it so no one else makes the same mistake I did.
