This repository is used by the SIMET team to help track the base firmware used in SIMETBOX images.

This repository may include hardware enablement support for equipments sold in Brazil that are not yet present upstream, or unacceptable for upstream. It may also include backports of functionality or fixes from later OpenWRT branches that are required for the SIMET system.

We attempt to send to OpenWRT upstream all changes we make, but some might be considered unsuitable by upstream. The exception are updates to end-of-life branches of OpenWRT (such as Chaos Calmer).

Relevant public activity is tracked here: SIMETBox project @ github/simetnicbr

SIMETBOX binary images available at the SIMET website are only for personal use, and cannot be used on ISP CPEs, due to password policy. They may be based on older OpenWRT release branches that were considered stable for that platform. This may include stuff as old as OpenWRT "Chaos Calmer", in which case that platform is considered a legacy hardware platform and might not receive all SIMET feature updates.

The chaos_calmer branch comes from a different remote than openwrt/openwrt, i.e. from openwrt/chaos_calmer (cloned also at simetnicbr/openwrt-chaos_calmer).

The branches may be rewound/rebased when appropriate (e.g. because of still-in-development hardware support that has not been accepted upstream yet, sourced from third parties).

Active branches for SIMETBOX:

• chaos_calmer (legacy production, backports) -- avoid, EOL upstream
• openwrt-18.06 (production, backports) -- avoid, EOL upstream
• openwrt-19.07 (production, backports) -- avoid, EOL upstream
• openwrt-22.03 (pre-production, hardware enablement, backports) -- EOL upstream
• openwrt-23.05 (pre-production, hardware enablement, build fixes)
• openwrt-24.10 (pre-production, hardware enablement)

Inactive branches for SIMETBOX:

• every other openwrt version.
