I've just received one of their new CrossConnect Pro units from Rowley
Associates, and have been trying it out.

It comes in a very smart laser-engraved black anodised aluminium
enclosure with a single LED, and is supplied with a long USB cable and a
target connection ribbon cable. The latter was rather short so I swapped
it for the cable from my CrossConnect Classic.

It required a new set of drivers which were available from the Rowley
web site, and a new version of CrossStudio 2.

I had a connection problem when I first tried it with an EA LPC2148
board, but that was soon fixed by using Adaptive Clocking instead of the
Auto setting. I also tried it on a Silica LPC2103 board.

It's about twice as fast as the CrossConnect Classic; I was getting a
download speed of 87.8 KB/s with a sizeable application, vs 42.4 KB/s.
Like the CrossConnect Classic, it supports "differential downloading",
which speeds the process up by only downloading those parts of the
application that need to be updated. The LED only flashes when data are
being transferred.

Apart from the increased speed, it behaves virtually the same as the
CrossConnect Classic. One thing I did notice is that it whereas the
CrossConnect Classic actually powers the target system when it is
plugged in to it, which I have always found a bit disconcerting, the Pro
doesn't.

That would be into flash. Into RAM the Classic will load anywhere between
500K and 800K/second.

I'm supposed to be receiving my Olimex target boards (STM32, and
lpc2106) either today or tomorrow so this weekend I can also give the
CrossWorks software a workout. Unfortunately I can't afford anything
fancy for the JTAG unit, I have two Olimex units the Wiggler and the
USB Tiny, and they will have to do for a couple of month.

So far CrossWorks in the lead, the Linux free software so far as I
can see has issues with being a work in progress for the Cortex chips
which I'm very interested in using for hobby projects.

I've only ever used it for LPC ARM chips, but they do support most ARM
variants. I've got an ST32 Primer (Circle) kit, but that has it's own USB
JTAG interface that'sused with the Raisonance software.
