硬件:imx8qxpC0-mek

软件:起初使用的l4.14.98_2.0.0的yocto编译出的rootfs.sdcard烧写到SD卡上,后来用l4.14.98_2.3.0:uboot,scfw,atf,kernel-image都是统一版本编译的并替换掉原来的flash.bin和image&dtb

hello.c:

#include<stdio.h>

int main(){

      printf("hello world\n");

        return 0;

}

在PC机上使用source environment-setup-aarch64-poky-linux重置环境变量之后,使用$CC hello.c -o hello_world

将hello_world拷贝到开发板的/home/目录下,chmod a+x hello_world

运行:./hello_world

无任何打印信息

使用gdb hello_world

"/home/hello_world": not in executable format: File truncated

想问一下这种问题如何解决?
