I'we got a ST-Link v2 USB dongle.
The firmware on it is: V2.J17.S4
Trying to upgrade the firmware to the latest V2.J30.S7
I'm using the software provided by ST:
- ST-LinkUpgrade_007(both win subfolder and java)
- STM32 ST-LinkUtility
All of the above software gave me the same error when trying to upgrade to latest version: "Upgrade Error, Please try again."
I am using Win 10, 64bit, ST-link Driver(009). The device is visible in the Device Manager.
(I also tried the exact same thing on Win 8, 64bit)
I would like to understand the problem, but the error didn't drop a code to look for, and the official documentation didn't mention it either.
I can eliminate OS related problem as i tried on 3 different machines. Looks like its a hardware issue, so I am closing this thread.
