NOTES

  • Note that your repo needs to be public, otherwise you have a strict monthly limit on how many minutes you can use.
  • Your session can run for up to six hours. Don't forget to close it after finishing your work, otherwise you will continue to occupy this virtual machine, making it impossible for others to use it normally.
  • Please check the GitHub Actions Terms of Service. According to the TOS the repo that contains these files needs to be the same one where you're developing the project that you're using it for, and specifically that you are using it for the "production, testing, deployment, or publication of [that] software project".

Flashing process for wrt32x

If you are not sure about your kernel partition size do a sysupgrade from command line Increasing mamba and venom kernel partition to 6MB

  1. Verify compatibility
   $ fw_printenv | grep "pri_kern_size"; #mamba MUST equal 0x400000
   $ fw_printenv | grep "priKernSize"; #venom MUST equal 0x0600000

Do not try to change them!

  1. Flashing process: You must always use a factory image when flashing to or away from a resized build.
  • Create a backup tar
  • Flash the image via sysupgrade: sysupgrade -F squashfs-factory.img
  • Restore the backup

Two times, to do the change from both boot partitions. Once, you will be capable of install updates without do this again
