v4.3.4-ssh
icedream
Carl Kittelberger
Engine OS v4.3.4 for Denon Prime 4 & Prime GO with OpenSSH server installed and configured.
Flash this onto your device by either using the provided USB-flashable image (.img), the self-extracting tools (.exe for Windows and .run for Linux).
Log in to your device by connecting it to a network via Wi-Fi or LAN and use username root and password denonprime4 (yes, it's exactly this for the Prime GO as well as it's a hardcoded value at the moment).
This unofficial image is not provided to you by Denon and is made available to explore the device for debugging and research purposes. Do not flash this for permanent use.
New updater tool
I am providing a newer updating tool that's not relying on the one packaged with the original firmware. Feel free to try it on your Denon device and report back if you find issues with it! I will pack the firmware with it as the _new.exe (for Windows) and .run (for Linux) experimentally moving forward from this release!

Notes for those curious about the repository
It has been a long while since I last touched this repository. I'm trying to get back into the spin of maintaining this repository. It is known that it is behind by several minor firmware updates. The last release and this one both get the repository mostly back up to speed by fixing up buildroot and the build scripts. I'm incrementally working towards the latest 4.3 version which should hopefully not take too long thanks to those changes. Hence expect more release notifications soon.
As a side thing to fixing up buildroot, I have isolated the actual buildroot configuration into its own repository at https://github.com/icedream/buildroot-enginedevices, usable as a br2-external tree. The intention is for this configuration to be easily to access and repurpose by other projects and repositories as I still consider this repository to be very experimental still. The many scripts used here are hacky and only made on best quick effort - they do not currently guarantee 100% reproducibility. Experimentation with Mixxx and other packages targeting Denon Prime 4 or Denon Prime GO will continue on a branch in that repository.
This time, a bunch of packages also needed fixing up due to the GCC 14 changes: The compiler defaults to C23 but many old pre- or around-2014 versions of software used by buildroot fails to compile with this new default. The build scripts have been updated to detect this condition and set a flag to change this back to gnu17 but the patches backport known fixes from upstream to mitigate other side effects directly in the source code. If you continue running into issues compiling pre-2014 versions of software with this buildroot, consider creating an issue so I can look at that or help with it.
For the future, I plan to get rid of the mess of .dts files that is contained in this repository. Moving forward, I will only supply .dts files for devices I actively build images for (at the moment Prime 4 and Prime GO only). The scripts currently auto-generate them based on the original image if they are missing but they take a long time to generate and really could be replaced by a template file, or possibly something even better integrated into buildroot. I do not intend to get rid of buildroot, it's been pretty foundational in understanding how Denon possibly put together the firmware and, most importantly, making getting back to working on this project possible easily and quickly.
Lastly, thanks for all the support and messages, private or public, regarding this project! It's good to be working on something knowing it is actively benefiting people.

This release was massively delayed due to breakages with gcc14 and several longer development breaks on my end. I'm back to working on this project but slowly incrementally working towards a fully working state.
