Attached is the latest version of the firmware which I found deep searching the internet. This version works on my POG boards.

I've also attached a docker script which follows your procedure to compile the last version to work, and in fact it does compile the firmware just fine, however when I load it into the POG board it knight riders and appears to be ready, however

Code: Select all

sudo pistar-findmodem
doesn't find it. I'm guess I've a miss configuration in the Config.h file or using a too new a library file.
Does the building convert the code into HEX file? For uploading via pi-star command? Thanks for sharing this.

The build script builds everything and leaves it in the docker image. I then copy out the file I want which yes is the hex file.

Install Docker Desktop to get started..

Code: Select all

docker build -t mmdvm . && docker run mmdvm cat bin/mmdvm.hex > mmdvm.hex
The first half of the command does the building of the firmware.. the "docker run" part starts the image to allow you to copy the file you want out.

If you want to play inside the docker container, maybe change some files or recompile then you can with:

Code: Select all

docker run -ti build bash
This will drop you into a bash prompt inside the container. NOTE when you leave the container it's stopped and no changes will be retained, so you can screw it up as much as you like, stop it and restart and your back to the beginning again. If you want changes to remain then you need to adjust the "Dockerfile".

Does your hex file work ok? I see you mention an issue?

no the one I compile doesn't work... well pistar-findmodem doesn't see it. The HEX I posted does work fine though.

I'm still tinkering with the build to try and figure out what's wrong.

I've come to the conclusion that it is a bad idea to provide custom firmware files on the forum.

You've said your hex file doesn't operate properly so if someone downloads and flashes your file then they are left with a device that does not work with no way to get it back working.

It is just best to leave it alone.

To anyone wanting his files and scripts, please contact him by PM or some other private means to transfer files.
If someones previous actions are any indication of their future actions, then I predict the deletion and removal of access will happen at any moment. 7-11-2020.
