Holy shit, that JLink is expensive. What does it get me more than the JTAG<->FTDI<->OpenOCD<->GDB setup that I have currently, who's boards cost my ~$100 in super low volume?

Just grab a cheap Chinese clone off of Ebay. They're pretty much completely functionally identical in my experience.

FWIW -- for non-commercial uses you can get a J-Link EDU for about $70. The hardware is identical to J-Link BASE.

JLink is updated very quickly and works with every arm platform and IDE imaginable.

Yes, this exactly. It is way ahead of OpenOCD if you are working with hardware released in the last 12-18 months.

I mean, GCC and OpenOCD had CortexM4 support before anybody else as far as I could tell. Keil and IAR wouldn't even give us a release date at the time.
