HiSilicon Cross-Compilation Toolchains

Cross-compiler toolchains extracted from HiSilicon SDKs, hosted as release assets for use in CI pipelines.

Toolchain Reference

arm-himix100-linux	6.3.0	uClibc 0.9.33.2	softfp	armv5te	ARM926, A9, A7, A17, A53, A73	arm-himix100-linux-	Hi3516EV200 series
arm-himix200-linux	6.3.0	glibc 2.24	softfp	armv5te	ARM926, A9, A7, A17, A53, A73	arm-himix200-linux-	Hi3516CV500, Hi3519V101

All toolchains default to soft-float ABI (gnueabi). Hard-float variants are available via multilib flags, e.g.:

-mcpu=cortex-a7 -mfloat-abi=hard -mfpu=neon-vfpv4

Archive Format

Most archives are .tgz files with a nested structure:

<name>.tgz
  +-- <name>/
      +-- <name>.tar.bz2    # actual toolchain
      +-- <name>.install     # vendor install script (not needed for CI)
      +-- runtime_*.tgz     # runtime libraries

Exceptions:

• arm-hisiv300-linux.tar.bz2 is the inner archive directly (no .tgz wrapper).
• arm-himix200-linux.tgz is split into two parts due to the 2 GB GitHub release asset limit.

Usage in CI

Extracting

# Standard .tgz archives (two-step extraction)
tar xzf arm-hisiv510-linux.tgz
tar xjf arm-hisiv510-linux/arm-hisiv510-linux.tar.bz2

# arm-hisiv300 (single-step, bare tar.bz2)
tar xjf arm-hisiv300-linux.tar.bz2

# arm-himix200 (reassemble split parts first)
cat arm-himix200-linux.tgz.part* > arm-himix200-linux.tgz
tar xzf arm-himix200-linux.tgz
tar xjf arm-himix200-linux/arm-himix200-linux.tar.bz2

Building

The vendor install script creates target/bin/ with absolute symlinks to /opt/hisi-linux/... which only work on the original install path. For CI, use the full CROSS_COMPILE prefix (from the table above) with the bin/ directory on PATH:

export PATH="$PWD/arm-hisiv510-linux/bin:$PATH"
make CROSS_COMPILE=arm-hisiv510-linux-uclibcgnueabi-
