I'm using 2 different ST-LinkV2s to put firmware on a ST32F429ZIT6 processor. I'm using the SWD interface. One of the ST-Links works and the other does not. The one that does not will not even connect to the device. I took both apart to look at the ST-Link boards. They are different. The one that works is sparsely populated while the other has more components on it. The one that works belongs to someone else and I must return it soon. What changed and why am I unable to get a SWD connection with the newer ST-Link?
I've perused the web and this forum and found many "solutions" and tried all of them - none worked.
I've attached a picture of the 2 St-Links.
Both boards are labelled ST-Link V2.0
MB 936 rev B
The one that works has not MFG code and the one that doesn't work has MFG Code 1142.
Any ideas would be appreciated.
