TF-A build fails on Arch Linux in include/lib/mmio.h
Open, Needs TriagePublic


flash-image.bin build for MACCHIATObin Single Shot, on Arch Linux x86_64, fails in include/lib/mmio.h.

To re-produce:

  • pacman -Sy aarch64-linux-gnu-gcc - currently it's aarch64-linux-gnu-gcc (GCC) 12.2.0.
  • export CROSS_COMPILE=aarch64-linux-gnu-
  • git clone
  • Clone the binaries-marvell and mv-ddr-marvell Git repos alongside the trusted-firmware-a, and check out revisions as recommeded in TF-A build instructions for Armada80x0.
  • Build u-boot.bin:
    • git clone alongside the binaries-marvell and mv-ddr-marvell repos.
    • cd u-boot
    • git checkout v2023.01 - the latest release.
    • make mvebu_mcbin-88f8040_defconfig
    • Change CONFIG_DEFAULT_DEVICE_TREE to "armada-8040-mcbin-singleshot" (inspired by this SolidRun doc).
    • Add arch/arm/dts/armada-8040-mcbin-singleshot.dts. Can be obtained from the latest Marvell kernel sources.
    • make, built fine, cool.
  • Trying to build TF-A:
    • cd ../trusted-firmware-a/
    • git checkout v2.8.0 - the latest release, as per changelog.
    • make PLAT=a80x0_mcbin MV_DDR_PATH=../mv-ddr-marvell SCP_BL2=../binaries-marvell/mrvl_scp_bl2.img BL33=../u-boot/u-boot.bin mrvl_flash - error:

czka added a comment.Sun, Feb 19, 3:34 PM suggests it's a problem with GCC, which was supposed to be fixed in GCC 12.1, but my GCC version is 12.2.0, and I can also reproduce those array subscript 0 is outside array bounds build errors in include/lib/mmio.h using the latest Arm GNU Toolchain from, which is based on GCC 12.2:

$ aarch64-none-elf-gcc --version
aarch64-none-elf-gcc (Arm GNU Toolchain 12.2.Rel1 (Build arm-12.24)) 12.2.1 2022120

Only know I found

So with arm-gnu-toolchain-11.3.rel1-x86_64-aarch64-none-elf the build went fine.
It might make sense to close this ticket then.
