Apparent bug in ST-LINK/V2 firmware V2.J28.S6

This isn't really a question - since I found a solution.  It's an observation in case others encounter a similar problem.


We purchased a new ST-LINK/V2 adapter recently and it shipped with firmware "V2.J28.S6".


We use this adapter along with a cable from Tag-Connect to program our boards (STM32F030C8).  However, I found that I could only program our board if the cable was connected before I start the Program+Verify operation.  (Related problem: the "Automatic mode" does not recognize when the cable is connected to our board - and the utility gets sluggish when I do).


Since the latest ST-LINK Utility included firmware version 27, I decided to "upgrade" my adapter from 28 to 27.


Once I did this, everything worked as expected.


It would appear that ST-LINK/V2 firmware V2.J28.S6 contains some kind of bug that does not exist in V2.J27.S6.


Anyone else seen this?
