I don't know the LPC17xx JTAG programming specs, is it public?
I had only a brief encounter with JAM/STAPL, and it was maybe a decade ago, but
I clearly remember that loops (and most probably also conditionals) were part of
the specs.

(X)SVF is a completely different issue, much simpler (read: less capable), I
admit.
Whether the tools can output a JAM file with all the required procedures, is a
different question (and I put it forth as a premise in my original post).
Nevertheless, if the programming requires relatively complex procedures which
are hard to play back from a "recording", it further disqualifies the JTAG thing
(after as it then can't be programmed on test/programming equipment
commonly available at various manufacturers.

"Send" clicked too fast... sorry.
I meant to say, that if the part cannot be programmed by simply playing back a "recording" through JTAG, after learning that there is no boundary scan either, the whole thing is then degraded to a fully proprietary interface, where using the "JTAG" designation suggesting a standard port with well established capabilities is somewhat misleading.
Not that we don't see that happen at other microcontroller families and vendors these days.

Hi,

You can program through the core; I believe everything you need is
available. I don't believe there is direct programming of the flash using
boundary scan.

Ahh, you're right. I wrote this some time ago, so my recollection is hazy.

I remember now--I looked at capturing a session and creating a STAPL script
from it, but could not catch the "do this until..." easily in our software.
Other things would be easy (go to this state, scan this data), but the
low-level software could not easily capture the "I need to do this until bit
is set of the data scanned out", for instance.

I dont think it would be too difficult to craft this by hand, but it is
hard to craft it by "recording", at least for our tools.

Don't loose your mind and faith.
Although that OpenOCD didn't work with LPClink but we could modified with low cost LPT Macgraigor(74HC or HCV that work with 3.3V bus) to program LPClink.So that able to work with OpenOCD.
The embeddedartis (LPCXpresso) didn't so sexy than STM32 discovery.
The old surfer knew that STM32 is the best for flash programmer.
Not only for 32-bits but also for 8-bits.And everybody knew that lust very cheaper...
After all the history was bonded.the NXP and Islands.

There is also the CoLinkEx, witch is hw open sourced and firmware
distribuited, the flasher firmware run in a lpc1343.
