由跨工具链构建时，受信任的固件编译错误

我正在开发瑞萨电子的rcar gen 3平台，尤其是在手臂信任固件级别。

    1. bootparam_sa0.srec Loader(Boot parameter)                <======= arm-trusted-firmware
    2. bl2-m3ulcb.srec Loader                                   <======= arm-trusted-firmware
    3. cert_header_sa6.srec Loader(Certification)               <======= arm-trusted-firmware
    4. bl31-m3ulcb.srec ARM Trusted Firmware                    <======= arm-trusted-firmware
    5. tee-m3ulcb.srec Open Portable Trusted OS                 <======= optee-os
    6. u-boot-elf.srec U-Boot                                   <======= u-boot

我通过Gcc v5.4通过命令构建了BL31

$ make ARCH = aarch64 CROSS_COMPILE = aarch64-linux-gnu- PLAT = rcar LSI = M3 RCAR_GEN3_ULCB = 1 RCAR_LOSSY_ENABLE = 1 RCAR_DRAM_SPLIT = 2 PMIC_LEVEL_MODE = 0 bl31 / p>

但是我遇到了以下错误：

"

相同错误：https://github.com/ARM-software/tf-issues/issues/417

汇编代码正确，显然不是问题。

似乎这取决于编译器。我正在尝试安装gcc / g ++ 7.4 cross：

http://ftp.br.debian.org/debian/pool/main/g/gcc-7-cross/gcc-7-aarch64-linux-gnu_7.4.0-1cross1_amd64.deb

http://ftp.br.debian.org/debian/pool/main/g/gcc-7-cross/g++-7-aarch64-linux-gnu_7.4.0-1cross1_amd64.deb

在Ubuntu 16.04上，将Makefile修改为使用gcc-7（交叉），g ++-7（交叉），但仍然出现此错误。我该如何克服这个错误？

您可以停止使用Linux发行版随附的工具链，而改为使用Linaro工具链：

wget https://releases.linaro.org/components/toolchain/binaries/latest-7/aarch64-elf/gcc-linaro-7.4.1-2019.02-x86_64_aarch64-elf.tar.xz
tar Jxf gcc-linaro-7.4.1-2019.02-x86_64_aarch64-elf.tar.xz -C /opt

git clone https://github.com/renesas-rcar/arm-trusted-firmware arm-trusted-firmware-renesas
cd arm-trusted-firmware-renesas
make ARCH=aarch64  CROSS_COMPILE=/opt/gcc-linaro-7.4.1-2019.02-x86_64_aarch64-elf/bin/aarch64-elf- PLAT=rcar LSI=M3 RCAR_GEN3_ULCB=1 RCAR_LOSSY_ENABLE=1 RCAR_DRAM_SPLIT=2 PMIC_LEVEL_MODE=0 bl31
