Don't use JTAG.
Use ISP (serial). Use FlashMagic, lpc21isp or the Philips Flash Utility.

Subject: [lpc2000] JTAG programming for production - LPC2148
Can anyone tell me what they use for mass programming thru JTAG?
In
other words, I know I don't have to give the technician a
wiggler and
the Keil GUI to program parts. Does anyone make some kind of
dongle
from serial to JTAG that will work? And which software? Flash
Magic?
I'm looking for a simple and inexpensive method for 4-5
technicians
to simply be able to program a LPC2148 with a given .hex file?
Thanks.

That is one good way and many bigger companies are doing it.
For real high-volume, you use pre-programmed chips. Many
semiconductor vendors or third party vendors provide this kind
of service.

Absolutely: the kind of volumes I'm talking about here are maybe 10k to
50k units per year, done in batches of a few thousand. The prorgramming
and test are highly automated, but there's still some manual handling
involved in the setup I described. If higher volumes are involved (say
100k+ per year), even more automation and optimisation as you suggest
are appropriate.
For anything more than a handful of units using tools designed for
development environments is not really apropriate. I'm not aware of any
JTAG based programming tools that would be suitable.

LPC parts have built in bootloader, so you can
program it anytime you want through the serial port.
By doing a reset with ISP pin in low state, the chip
enters into ISP mode and the bootloader starts to run.
If you send "?" at 9600 bps and no parity the
chip must answer with "Synchronized", wich means the
bootloader is up and running.

We use jtag since the ISP requires a serial circuit. The program is
downloaded using the Keil IDE via uLink jtag adapter. The free
version of the Keil IDE has a point/click GUI to select a device in a
jtag chain which has several LPCs on it.
The uLink w/ eval board is around $300.
I could have recommended a $20 jtag parallel port dongle and HJTAG
($free), but I don't want my neck on the line when units come back due
to bad programming. Whatever you end up using, make sure that it
doesn't result in returned units which will result in more cost to
deal with than having invested in good tools in the first place.
Hope this helps,

Win,
Just out of interest, when you say there's several LPCs in the chain,
does that mean they can be programmed in parallel?
Also, how long does it take (approximately) to program the devices like
this?

Hi Brendan,
We don't have a high volume product, so we just have techs program
each device manually via ulink + Keil IDE. There are 4 devices in the
jtag chain, so programming time is the time to select one device +
flash via IDE, multiplied by 4.
Our HW folks did not expose the serial pins, and so the ISP method is
not an option.
