+===== Identify Version =====
+There are two ways to identify the version of your VIM4.
+*/
+===== Identify by CPU Screen Printing =====
+CPU has a CPU-ID label on the top center side, maybe need to remove the heatsink if it is installed.

+| [[../#vim4-with-npu|New VIM4 with NPU]]  | A311D2-N0D    |
+===== Software-way identification =====
+Going into Linux-shell and type
+```shell By CPU Serial Number
+grep -ohm1 360[b\|c].* /proc/cpu*
 ```
-**For ttyS0**:
+```shell by CPU Revision
+cat /sys/devices/soc0/revision
+```

+<tabbox Linux 5.4>
+You can use command ''uname -r'' to get your kernel version, if your kernel version is ''5.4.xxx'' then you can use the command below to get the cpuid.
 ```shell
-sudo cp /lib/systemd/system/serial-getty@.service /lib/systemd/system/serial-getty@.service.backup
+cat /proc/cpuinfo | grep Serial | awk '{print $3}'
-sudo sed -i "s/ExecStart=.*/ExecStart=-\/sbin\/agetty --autologin khadas --keep-baud 921600,115200,38400,9600 \%I \$TERM/g" /lib/systemd/system/serial-getty@.service
 ```

+<tabbox Linux 5.15>
-Reboot to take effect.
-</WRAP>
+You can use command ''uname -r'' to get your kernel version, if your kernel version is ''5.15.xxx'' then you can use the command below to get the cpuid.
-<WRAP tip >
-If you want to recovery the login prompt, please follow the steps below:
 ```shell
-sudo mv /lib/systemd/system/getty@.service.backup /lib/systemd/system/getty@.service
+cat /proc/cpu_chipid| grep Serial | awk '{print $2}'
-sudo mv /lib/systemd/system/serial-getty@.service.backup /lib/systemd/system/serial-getty@.service
 ```
-</WRAP>
+</tabbox>
+You can identify the version via different CPU ID as below:
+  * 360bxxxxxxxxxxxxxxxxxxxxxxxxxxxx - If the serial starts with ''360b'' then it is **VIM4**
+  * 360cxxxxxxxxxxxxxxxxxxxxxxxxxxxx - If the serial starts with ''360c'' then it is **New VIM4**
