 Oh hell, this is going to take ages on the Raspberry Pi 2...
 
+Meanwhile on my main laptop:
+
+I thought I might try to compile it on my main machine and just do the installation
+on the Raspberry Pi 2 as the compilation is still running (5½ hours later).
+
+~~~console
+$ sudo pacman -S arm-none-eabi-gcc arm-none-eabi-newlib
+$ git clone git@github.com:g4klx/MMDVM_HS.git
+$ cd MMDVM_HS
+$ scp raspi2:git/MMDVM_HS/Config.h .
+$ make
+~~~
+
+I got some errors about `usbserial` or `USBSerial::begin()`. A short research
+suggested a `depmod -a` and you know what, it compilled.
+
+Well, I had to run it as _root_.
+
+Now it is time to put the compiled firmware to the Raspi and install it.
+
+~~~console
+$ scp bin/mmdvm_f1.bin bin/mmdvm_f1.elf bin/mmdvm_f1.hex  raspi2:git/MMDVM_HS/bin/
+~~~
+
+Back on the Raspi: the installation won't work as there is no stm32flash installed. Huh?
+Oh well, I could not find it in any repository. The AUR website has a package, but I
+can't find it with pacman or paru. So we install by hand again:
+
+~~~console
+$ git clone https://aur.archlinux.org/stm32flash.git
+$ cd stm32flash
+$ makepkg -si
+~~~
+
+sudo pacman -S libgpiod
+
+And again, back in the firmware repository at `~/git/MMDVM_HS`:
+
+~~~console
+$ sudo make mmdvm_hs_hat
+~~~
