Using Upstream OpenWrt with Gateworks Products

Gateworks takes an active role in the OpenSource community and as such continually submits patches to upstream projects like the Linux kernel, the U-Boot bootloader, and OpenWrt. As such pre-built OpenWrt images and packages from the upstream OpenWrt auto-builders generally work very well.

You can find pre-built artifacts at ​https://downloads.openwrt.org/.

Image Selector

If you are not sure exactly what your looking for, you can use the image selector at ​https://firmware-selector.openwrt.org:

  • enter a model to search for
  • select a release
  • click on the download icon on the image found

The ​image selector also allows you to request a custom build tailored to your needs:

  • instead of clicking on the download button you can expand the 'Customize installed packages and/or first boot script' and customize:
    • add packages to the installed package list
    • add a script to run on first boot (click the gear icon for an example and script instructions)

Release Versions

There are two types of pre-built releases:

  • Stable release branches: OpenWrt tries to create a stable release branch once a year and will have maintenance releases that get pre-built images/packages several times during the life of that branch.
  • nightly development snapshot: builds are against the 'main' development branch with bleeding edge features and thus a moving target. It is advised to use the stable release branches whenever possible.

If using an upstream pre-built image it will be a minimal package install and you can use package management to install pre-built packages in the OpenWrt package feeds:

  • 24.10 / 23.05 stable releases:
    • these use OPKG based on /etc/opkg/distfeeds.conf
    • see ​opkg
    • examples: 
      # show installed packages
opkg list-installed
# update package feeds (/etc/opkg/distfeeds.conf}
opkg update
# install a kernel config package (enable kernel config in /proc/config.gz)
opkg install kmod-ikconfig
# install ath11k support for qcn9074
opkg install kmod-ath11k-pci ath11k-firmware-qcn9074
  • SNAPSHOT builds:
    • as of Nov 2024 OpenWrt uses APK (instead of OPKG) based on /etc/apk/repositories.d/distfeeds.list
    • see:
    • examples: 
      # show installed packages
apk list --installed
# update package feeds (/etc/apk/repositories.d/distfeeds.list)
apk update
# install a kernel config package (enable kernel config in /proc/config.gz)
apk add kmod-ikconfig
# install ath11k support for qcn9074
apk add kmod-ath11k-pci ath11k-firmware-qcn9074

Venice

Venice is supported in the nightly development builds (SNAPSHOT) as well as the 24.10 stable releases:

These images are in the form of compressed disk images which are typically installed via U-Boot:

Ventana

Ventana is supported in the nightly development builds (SNAPSHOT) as well as the 24.10 and 23.05 stable releases:

Instructions for installing NAND flash images:

Instructions for creating Ventana JTAG images from NAND flash images: 

# fetch mkimage_jtag script and make it executable
wget -N https://dev.gateworks.com/jtag/mkimage_jtag
chmod +x mkimage_jtag
# fetch boot firmware (SPL and U-Boot)
wget -N https://dev.gateworks.com/ventana/images/SPL
wget -N https://dev.gateworks.com/ventana/images/u-boot.img
# create an image for 'normal' flash geometry (most boards including newer 2GiB boards)
./mkimage_jtag SPL u-boot.img gateworks_ventana-squashfs-nand.ubi  > ventana_normal.bin
# create an image for 'large' flash geometry (some older 2GiB boards)
./mkimage_jtag SPL u-boot.img gateworks_ventana-large-squashfs-nand.ubi> ventana_large.bin

Upstream OpenWrt 24.10 branch:

The 24.10 branch can be summarized as:

  • Linux 6.6 kernel
  • pre-built image support for Venice (compressed disk image) and Ventana (normal flash geometry ubi)

Upstream OpenWrt 23.05 branch

The 23.05 branch can be summarized as:

  • Linux 5.15 kernel
  • pre-built image support for Ventana (normal flash geometry ubi)
