楼主，我编译子程序，base_platform会产生编译warning，提示该选项已被弃用，不知道是否会对动态加载产生影响？
移植后，主程序调用子程序export出来的接口，会卡死在主程序中：
主程序调用如下：
err=dl_load_file(&use_handle,"0:module.axf");
if (err == DL_NO_ERR)
{
printf("open module.axf ok\r\n");
test_cnt = dl_get_func(&use_handle, "test_cnt");
printf("test_cnt func:0x%p\r\n", test_cnt);
test_cnt(1000, 1);
printf("test_cnt done\r\n");
export_func=dl_get_func(&use_handle,"export_func");
printf("export_func:0x%p\r\n", export_func);
export_func(showtips);
printf("export_func done\r\n");
}
加载子程序的打印信息：
