编译uboot时报错unrecognized command line option ‘-mgeneral-regs-only’

james8422

我按照《I.MX6U 嵌入式 Linux 驱动开发指南》中的方法尝试编译NXP的IMX8MQ-evk的uboot、虽然一个是IMX6一个是IMX8、但是我觉得应该是通用的、uboot源码是clone的https://source.codeaurora.org/external/imx/uboot-imx的imx_v2020.04_5.4.70_2.3.0分支、
arm-linux-gnueabihf-gcc版本是：gcc version 7.5.0 (Ubuntu/Linaro 7.5.0-3ubuntu1~18.04)


执行：
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- distclean
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- imx8mq_evk_defconfig
make V=1 ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- -j2


报错：
arm-linux-gnueabihf-gcc: error: unrecognized command line option ‘-mgeneral-regs-only’

百度了一下基本上都是说编译器问题、尝试过使用正点原子推荐的4.9.4版本gcc、也会报同样的错误、而且会显示：*** Your GCC is older than 6.0 and will not be supported、

求问、

补充：我编译imx6的、也就是make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- mx6ull_14x14_evk_emmc_defconfig、make后编译可以成功、头疼

好了解决了、我真是愚蠢、imx6ull的CPU是Cortex-A7（ARMv7）、imx8mq的CPU是Cortex-A53（ARMv8）、ARMv是32位的不用说、ARMv8指令集为aarch64兼容aarch32、也就是我需要一个编译64位的交叉编译工具链、所以当然不能用arm-linux-gnueabihf-gcc、应该用aarch64-linux-gnu-gcc、愚蠢、真是过于愚蠢、
