Firmware generator for sprtch printer interface

Requirements

To correctly set the wpa_supplicant WiFi passwords for the target build you need to have pass configured with four different password:

  • sprtch_home_ssid
  • sprtch_home_pass
  • sprtch_sprtch_ssid
  • sprtch_sprtch_pass

Generate firmware image for RPI

To generate the RPI firmware you should use the buildroot variable stored in the sprtch_defconfig file.

git submodule init
git submodule update
cd buildroot
make BR2_EXTERNAL=../ sprtch_defconfig

On package update

When one of the custom package I use has to be updated the first step is to update the <pkg_name>_VERSION in /package/<pkg_name>/<pkg_name>.mk file with the latest commit reference.

The second step is to rebuild the package that has to be updated.

cd buildroot
rm dl/<pkg_name>
rm output/build/<pkg_name>-<commit> -rf

Create a new package

To create a new package to add to the target you first need to create a new folder in /package/<name> containing the following files:

  • Config.in
  • <name>.mk

Refer to the documentation depending on the type of package you want to build. Once the package is correctly defined add a reference to this new package in the /Config.in file.

echo "source \"$BR2_EXTERNAL_sprtch_PATH/package/despinassy/Config.in\"" >> ./Config.in

Tick this new package in the make menuconfig and then export this new version with make savedefconfig
