# RutOS cross-toolchains — r16279-5cc0535800

Extracted from the RutOS GPL SDK trees on `map.consilio.at:/RUTX_R/`, 2026-08-18.
Only `staging_dir/toolchain-*` is included; the rest of each ~13 GB SDK is build tree.

| archive | target | arch | SoC |
|---|---|---|---|
| `toolchain-mips_74kc_gcc-8.4.0_musl.tar.zst` | RUT950 / RUT955 | mips, big-endian | Atheros Wasp 74Kc, 550 MHz |
| `toolchain-mipsel_24kc_gcc-8.4.0_musl.tar.zst` | RUT956 | mipsel, **little-endian** | MediaTek 24KEc, 580 MHz |
| `toolchain-mips_24kc_gcc-8.4.0_musl.tar.zst` | TRB2 | mips, big-endian | — |

All three GCC 8.4.0 / musl. Source SDKs, all at RutOS revision `r16279-5cc0535800`:

    /RUTX_R/rutos-ath79-rut9-gpl      15 G
    /RUTX_R/rutos-ramips-rut9m-gpl    11 G
    /RUTX_R/rutos-ath79-trb2-gpl      13 G

Verified at creation: `zstd -t` clean, sha256 matches `SHA256SUMS`, ~3,480 entries listable each.

These are the exact compilers that built the `rproxy` / `cproxy` binaries currently deployed to the
fleet. Keep them: those binaries cannot be reproduced without them, and nothing else records which
GPL release they came from.

Usage and the container build: see `toolchain/README.md` in the `tmagent` repo.
