Fresh Compile

# Reset everything

# Choose a specific version and init
git checkout openwrt-22.03

Set the board:

• Target System -> Qualcomm Atheros IPQ40XX
• Target Profile -> Compex WPJ428

Then activate:

• Luci -> Collections -> Luci (default)
• Luci -> Protocols -> luci-proto-modemmanager
• Luci -> App -> luci-app-sqm
• Luci -> App -> luci-app-openvpn
• Luci -> Themes -> OpenWRT
• Utilities -> qmi-utils (required by our script promsignal)
• Utilities -> strace
• Utilities -> Terminal -> Picocom

Check that these packages were activated automatically:

• Kernel Modules -> USB -> kmod-usb-net-cdc-mbim
• Kernel Modules -> USB -> kmod-usb-net-cdc-ncm
• Network -> ModemManager
• Network -> tcpdump
• Utilities -> dbus

Note: do not use defconfig / diffconfig / etc. because they do not work when we upgrade between major versions. They tend to create frankenstein builds. So really avoid them, we lost enough time with this feature.

make download
make -j $(nproc)
