OpenRTX

Modular Open Source Radio Firmware

OpenRTX is a free and open source firmware for digitam ham radios, top-down designed with modularity, flexibility and performance in mind.

Currently OpenRTX is being actively developed for the TYT MD-380/390 and MD-UV380/390.

This firmware is highly experimental and is not in a usable state right now, however contributions and testing are welcome and accepted.

Compilation

To build and install the firmware, first clone this repository:

git clone https://github.com/n1zzo/OpenRTX

The following steps depend on the selected platform:

Linux

The OpenRTX linux build depends on libSDL, on Ubuntu you can install it with:

sudo apt install libsdl2-dev

The firmware can be compiled with:

meson builddir
meson compile -C builddir openrtx-linux

TYT MD-380 / TYT MD-UV380

To build the firmware you need to have a toolchain for the ARM ISA installed on you system, you can install one using your package manager.

For example on Ubuntu you can install arm-none-eabi-gcc

sudo apt install gcc-arm-none-eabi

You can then proceed in building the firmware:

meson builddir --cross-file cross_arm.txt
meson compile -C builddir openrtx-md380

If everything compiled without errors you can connect your radio via USB, put it in recovery mode (by powering it on with the PTT and the button above it pressed), and flash the firmware:

make flash

Now you can power cycle your radio and enjoy the new breath of freedom!
