MiyooCFW Cross-Compile Toolchain v2.0.0 Latest
Latest

This toolchain may be used to compile software for the upcoming MiyooCFW 2.0 release. Software built with this toolchain should also be backwards-compatible with the 1.3.3 release.

Notable changes:

  • This toolchain uses musl libc (the Miyoo 1.3.3 toolchain used uClibc)
  • This toolchain uses gcc10
    • This may change to gcc11 in a future 2.x release; 10 was chosen due to a limitation with our current buildroot version's external toolchain support

For local use:

  1. Download and extract the toolchain to /opt/miyoo
  2. Set the following environment variables when compiling your software: 
    CROSS_ROOT=/opt/miyoo
CROSS_TRIPLE=arm-buildroot-linux-musleabi
SYSROOT="${CROSS_ROOT}/${CROSS_TRIPLE}/sysroot"
PATH="${CROSS_ROOT}/bin:${SYSROOT}/usr/bin:${PATH}"
ARCH=arm
CROSS_COMPILE="${CROSS_TRIPLE}-"

Or use the provided docker image:

  1. docker pull miyoocfw/toolchain:2.0.0
    • The 2.0, 2, and latest tags also currently point to this release, but will be updated over time, as appropriate.

To use this this release as an external buildroot toolchain, please set the following Toolchain options in make menuconfig:

  • Set Toolchain type to External toolchain
  • Set Toolchain to Custom toolchain
  • Set Toolchain origin to Pre-installed toolchain
    • Or, to download it at build-time, set it to Toolchain to be downloaded and installed
  • Set Toolchain path t0 /opt/miyoo
    • Or, to download it at build-time, Set Toolchain URL to https://github.com/MiyooCFW/toolchain/releases/download/v2.0.0/miyoo-toolchain-v2.0.0-arm-buildroot-linux-musleabi_sdk-buildroot.tar.gz
  • Set Toolchain prefix to arm-buildroot-linux-musleabi
