Keil Toolchain supports SWD

http://www.keil.com/support/man/docs/ulink2/ulink2_ctx_jtag_adapter.htm

I'm sure there are others

Google ''Toolchain vendor name + SWD''

Hello again,

As my question went unanswered, I have to repeat it.

What software / hardware tools support SWD? So far I know IAR and a new J-Link does.

As I will need another JTAG/SWD debugger hardware, which ones support SWD?

My new project has a space constraints, so I need to use small connector.

Much appreciate your help.

Jan,

As one of the guilty parties - I apologize.

However I'd like to present my firm's ''work-around''

to your ''size-constrained'' requirement. We do not

use any connector. Instead we employ a 1x8 or 2x4

array of pth (plated thru holes) on 0.1'' centers.

We introduce JTAG signals via mating, spring-loaded

test pins. We've designed small, economical fixture

and have programmed 100's of boards in this manner.

Now during development - while the JTAG ''STAYS'' on -

we insert a standard header and leave the JLink on.

One final point - as mentioned previously - we measured

huge ''speed-up'' when comparing JTAG to SWD. I have noted

programmer's efficiency increase as we reduce the delay

between code changes and, ''did that work???'' We want to

keep the programmer's focus - waiting is NOT your friend...

Thank you for all responses.

Much appreciated.
