After a couple of successful experiments with my shiny new STM32F-discovery board, I thought I would give the STLINK-V2 programmer a try. It all works very nicely once you have set the thing to SWD mode in the target properties.
This was good even with a standard 20 pin connector.
Then I went to a 10 pin connector. Still good.
Then I started disconnecting wires that did not look like they were needed according to the SWD details.
I ended up with only four wires connected to my target (STM32F103RE):
Fantastic! Still works just fine and I only need a four-pin connector on my target.
So, the question is.. Using Crossworks is there any reason why I should re-connect the RESET pin to the programmer. I am guessing that the SWO pin is certainly not used but are there any circumstances where Crossworks needs the RESET pin?
How about other ARM targets?
