编译zcu102的U-Boot源码时遇到问题

Question

当我根据xilinx.wiki构建U-Boot时，遇到以下错误消息，有人可以帮助我吗？

尝试寻找相关解决方案，包括修改Makefile中的交叉编译器，但还是报错 第 249 行是我添加到 Makefile 中的内容

244 # set default to nothing for native builds
245 ifeq ($(HOSTARCH),$(ARCH))
246 CROSS_COMPILE ?=
247 endif
248
249 CROSS_COMPILE = arm-linux-gnueabihf-

Answer 1

aarch64-linux-gnu-的交叉编译器
