Enhanced Write Filter (EWF) provides the ability to write-protect a run-time image. By redirecting all write requests to either a separate disk partition(Disk mode) or RAM(Ram-Reg mode).
+
-
 
+
-
== How many modes does EWF has? ==
+
-
 
+
-
There are Disk mode and Ram-Reg mode.
+
-
 
+
-
== What's different about the modes? ==
+
-
 
+
-
'''Ram-Reg mode''' works by clear all the write requests when reboot.
+
-
1.System will restore when reboot.
+
-
2.Doesn't need any other invisible partition.
+
-
 
+
-
'''Disk mode''' works by the check point and restore.So Disk mode needs an invisible partition to save the write request of the check points.
+
-
1.Can set 9 check points.
+
-
2.Doesn't restore when reboot only if enter a restore commend.
+
-
3.Need an invisible partition in storage.
+
-
4.If you will do a big write request , ex:download some file , please disable the EWF first.
+
-
If the size of the write request is bigger than the size of the invisible partition. The WES will be crash.
+
-
5.There are no Disk mode in WES7.

+
1.Use make to compile the test file. After completion, you can enter the BIN folder and execute the test program.
-
1&2.Choose the EWF partition.
+
[[Image:NEX-001menu.jpg]]
-
3.Enable EWF.
+
2.Select the model or use the scanner to read the hardware information, if there is none, you can skip
-
4.Disable EWF.
+
3.Select the function to test
-
5.Commit EWF-In RAM-Reg mod:Can do change on OS without reboot.In DISK mode,the layer will set to 1.
+
'''Note: NEX-001 cannot use functions 4, 5, and 6'''
-
6.Clear the command which you chose.
+
== How to test NEX-001 COM? ==
-
7.Show the drive information.
+
1. You need a device to receive the signal. We use RS485 to RS232 as a test tool
-
8.Show the EWF information.
+
[[Image:NEX-001com_cable.jpg]]
-
9.Reboot.
+
2. Check the CCA1 signal and connect it correctly
-
10.After choose the EWF partition,here will show the EWF infomation.
+
[[Image:NEX-001com_CCA1.jpg]]
-
11.You can set checkpoint when DISK mode.
+
3.In the program, select ALL TEST to see that the COM option is correct when it is completed
-
12.Choose the layer which you want to restore.
+
[[Image:NEX-001com_comport.jpg]]
-
13.You can restore the system when DISK mode.
 
-
14.Go to layer1 , and the other layer will disappear.
+
== How to test NEX-001 CAN? ==
 +
1.A parallel line is needed to connect can0 and can1 with DuPont line
