STM32407G Discovery board demo code not working

Question asked by Pilot B on Apr 11, 2018

Hello everyone,


I ordered a STM32407G Discovery board. I opened the box, followed the steps, connected the device with my PC(Windows 10). The board worked like a mouse - it moved a bit of slow and not accurate. But basically worked.


Then I setup the development environment. Compiled the sample code. Connected the board to my PC again:

1. But the cursor not moved anymore. I used USB analyzer. But there is nothing sent to my PC.


2. Then I used "ST-Link Utility" to download the "STM32F4-Discovery_FW_V1.1.0\Project\Demonstration\Binary\STM32F4-Discovery_Demonstration_V1.0.0.hex" to the board. It was still not working. The mouse cursor didn't move.


Is there a way to get the original firmware shipped with the board?

Or, how to fix this issue?


This is similar to: Broken STM32F4 Discovery mouse!
