Hi all,
I want to get into the LPC2106 or similar mcu, and i'm moving from the
AVR world. I've read many things about how you need some bootloader or
something working on the mcu to receive data from the jtag, etc.
is there some detailed explanation regarding this issue and how to
solve it? Also, I'm looking for a programmer to build for the LPC2106.
I see several schematics listed in the files, which one would you guys
recommend? The standard wiggler? I found these ones online as well:
http://home.comcast.net/~staskh/projects/tools/
http://www.adilam.com.au/ARM/arm.html
Sorry if these questions are stupid and I missed something very obvious.

The LPC2000 series have their own builtin bootloaders. Part of the
Flash memory is protected and that is where it resides (8K). A
bootloader utility can be found on
http://www.standardics.philips.com/support/techdocs/microcontrollers/
it is called "LPC2000 Flash ISP Utility". >is there some detailed explanation regarding this issue and how to

JTAG is not a "programmer", it is a test interface (Joint Test Action
Group == JTAG). Most of the people here use simple wigglers, they can
give you information as to that, or search the messages for "JTAG" and
"wiggler". That should get you a lot of hits.
For myself, I've found wigglers to be slow, unstable, and, at times,
unpredicatable to get working right. For my current project (dual CPU
board: LPC2106 + LPC2138), I chose to spend the money ($2700) and
purchase an Abatron BDI2000. I've not been unhappy with it! It can
also program the Flash of the controllers as well as give me a stable
JTAG interface to gdb + Insight. That being said, you can whip up a
wiggler in about an hour and a few dollars expendature, then use a
software TCP server which you can download and compile yourself.
The BDI2000 is fast when programming the Flash memory. For example, a
34K file would take about 10 seconds to prgram using the serial utility
only takes about 3 seconds with the BDI2000, and it does it via the JTAG
with two commands. While 10 seconds is not a lot of time, I expect my
program to get a lot larger than 34K!

My interface is in jtag.zip, it works fine with the Crossworks tools.

Hi Tom,
Do you have an URL for that software TCP server?

Hello,
gdb-jtag-arm doesn't support ARM7 targets, only ARM9TDMI. The ARM9 code has
bugs, and I wouldn't count on its operation.
Macraigor (the company that sells the original "Wiggler") allows you to
download their on-chip debug software for free. I used it with an Amontec
Chameleon in its Wiggler configuration, but only on windows, the wiggler
isn't supported by their linux version.
Regards,
Dominic

That is a wiggler, we were talking about a JTAG gdb-server.

What? Under OCD Commander, the HBR command doesn't work for you? That's
very odd.
I've used hardware breakpoints before, and if you really want to get
tricky, you can access the ICE-breaker registers from OCD commander as well.

My interface works at full speed, perhaps I have a better PCB design. I
wasn't very impressed by the layout on the genuine Wiggler I have, and mine
is faster than that.

Newer versions of ocdremote support the hbreak command, they have
also added another monitor command:
monitor softbkpts off
this means that all breakpoint requests by insight/gdb will be set
as hardware breakpoints, which means when enabled stepping etc works
correctly in Flash.
to resume the default behaviour type monitor softbkpts on
Hope this helps.
