WM2000 - FAQ - Using EV Board & Recovery tool for Production

Frequently, when a new product is designed around the WM2000, we get questions from customers on how to mass-load the firmware into the modules. This is where our WM2000EV board comes into play.

It is important to note that this process needs to happen before the modules are soldered onto the final PCB. 

We have designed a python file that can be called using command prompt. It is available from our GitHub page. There are instructions on what needs to be installed and how to run the application on the GitHub page.

To help in understanding how to use the command, we have made a batch file that will call the command and allow for continued upload without recalling the program. To use the batch file, place the file into the root folder of the recovery tool.

The appropriate files to include should be placed within the fw\wm2000 folder. If you are going to upload the main app, or what we usually refer to as App1, please also place the file here for easy tracking. The content of the folder should look something like this.

Next, open the batch file in notepad and make the appropriate changes to the files. Please also make sure the COM number that the EV board shows up as in your computer.

You can use Device Manager to see which COM number the EV Board occupies.

Once all is done and saved just Issue the command .\update.bat to start.
