Hello guys,
โ
Recently, my ST Discovery F407 board was working just fine, until I received the following error in a txt. File: โthe interface firmware failed to reset/halt the target mcu.
โ
I have updated its frimware toโ 2.37.26, but the problem is still there. I have also tried to reset through connecting Boot0 to VDD, but it didn't work either. Still, I receive the same error each time I connect it to the PC. The Keil program is also saying "target is not connected" every time I try to download my code.
โ
I would be so much thankful if you help me with this!

Boards typically don't just quit all of a sudden. You didn't do anything or change something when it stopped working?
Does STM32CubeProgrammer have any better luck?
Reboot the computer.

Thanks for youre reply,
I did nothing other than updating its frimware or downloading my code. I have tested on 3 PCs but no difference.
By Using STMCubeโ, you mean using it for updating the frimware or for setting the peripherals?
I have used STMCube for setting up the peripherals, but not for updating the frimware. โ

Well, I thought I would never โbe able to solve this :D:D but I did.
The thing is that I don't get it how!โ

I have removed the JP3 and also shorted JP1 and tried to upgrade the firmware with STM32CubeProgrammer. The problem solved!
I thought I've lost my Discovery board forever! :beaming_face_with_smiling_eyes:

Thanks for your help guys.
