- Install
W0CHP-PiStar-Dash
curl -Ls https://w0chp.net/WPSD-Install | sudo env NO_SELF_UPDATE=1 bash -s -- -idc- Grow your root Partition if needed:
# Check which partition is your root (/) partition
# In my case it was /dev/sda2
mount
# Install cloud-utils for growpart
sudo apt-get install cloud-utils
# Grow root partiion
sudo growpart /dev/sda 2
# Resize filesystem
sudo resize2fs /dev/sda2- Compile Firmware:
# Install dependencies. Some of them are probably not needed.
sudo apt-get install git gcc-arm-none-eabi gcc-arm-none-eabi gdb-arm-none-eabi libstdc++-arm-none-eabi-newlib autoconf libtool pkg-config libusb-1.0-0 libusb-1.0-0-dev
# Download the precompiled flashing tool
curl -OL https://www.bi7jta.org/files/fm-patch/firmware/stm32flashV5
# Clone the repo MMDVM and it's Subrepos
git clone https://github.com/g4klx/MMDVM.git --recurse-submodules
cd MMDVM/
# Configure it (Example which i use ATM below)
nano Config.h
# Clean (just in case) and build
make clean
make dvm
cd ..
# Kill the MMDVMHost and related processes
sudo pistar-services fullstop
# Flash the new Firmware
sudo ./stm32flashV5 -v -w ./MMDVM/bin/mmdvm_f4.hex -R -i 20,-21,21:-20,-21,21 /dev/ttyAMA0/*
