This repo contains pre-compiled crust firmware blobs for the pinephone.
The pinephone crust build requires a or1k-linux-musl compiler. Buildroot cannot (at present) build multiple toolchains at once, and Skiff configures it to compile software for the Pinephone CPU (arm64). As a workaround, this repo is downloaded and the blobs used from here.
Compilation steps:
- Acquire cross compilers:
- Or using crossdev:
- crossdev -t arm-linux-musleabi
- crossdev -t aarch64-linux-musl
- crossdev -t or1k-linux-musl
- Init submodules
git submodule update --init - Build: "make"
Compiled from versions:
- arm-trusted-firmware version a1f02f4
- crust version v0.5
- u-boot v2021.10 w/ patches
