官网提供的可执行文件是基于64位Linux的:zynq_linux.tar.gz.

对于32位的系统,需要自己编译,解决方案如下:

1) 下载代码:git clone

2) 配置工程:

cd qemu-xarm

./configure –target-list=arm-softmmu –disable-werror –disable-kvm

3) 编译: make

4) 编译结果:

$ ls -l arm-softmmu/qemu-system-arm

-rwxrwxr-x. 1 walt waltNov 6 15:27 arm-softmmu/qemu-system-arm

5) 检测环境是否OK,测试如下:

$ ./arm-softmmu/qemu-system-arm -h
