+注意：此处定义OpenAMP通信设备共享内存起始地址为0x70000000，可根据实际内存分配进行修改。
+
 4. 将编译好的KO模块、用户态程序，以及zephyr.bin镜像拷贝到OpenEuler Embedded 系统的目录下。如何拷贝可以参考使用手册中共享文件系统场景。
 
+5. 将OpenAMP的依赖库libmetal.so，libopen_amp.so，libsysfs.so拷贝至文件系统/lib64目录。如何拷贝可以参考使用手册中共享文件系统场景。
 
 #### 使用说明
 
 1.  在openEuler Embedded系统上插入内核KO模块cpu_handler_dev.ko。
 
+````
+    insmod cpu_handler_dev.ko
+````
+
 2.  运行rpmsg_main程序，使用方式如下:
 
 ````
     ./rpmsg_main -c [cpu_id] -b [boot_address] -t [target_binfile] -a [target_binaddress]
     eg:
-    ./rpmsg_main -c 3 -b 0xc0000ffc -t /tmp/zephyr.bin -a 0xc0000000
+    ./rpmsg_main -c 3 -b 0x7a000ffc -t /tmp/zephyr.bin -a 0x7a000000
 ````
 
+此处定义Client OS起始地址为0x7a000000，启动地址为0x7a000ffc。
+
+注意：以上述demo为例，需要预留出地址0x70000000为起始的内存用于OpenAMP demo和Client OS启动。通过QEMU启动时，当指定-m 1G时默认使用0x40000000-0x80000000的系统内存。添加内核启动参数`mem=768M`，可预留地址为0x70000000-0x80000000的256M内存，可根据实际情况进行调整。
