Hi,
a lot of talks about the Wiggles, JetJTAG, other debuggers and download
speed.
But I've got a problem:
I am running both GDB and RealView debugger on a laptop without parallel
port support. I was able to borrow this together with a Jeeni but have
problems. EPI states (I've heard) that Jeeni does not work on the
lpc21xx
and indeed, with gsb it fails. It does work with the RealView debugger but
may suddenly hang (something about resynch).
Does OCD Remote work with RealView debugger?
Is a USB/Parallel converter supported (I could buy one)?
There is defenitely no budget for one of the (expensive) commercial JTAG
pods and what I've got does not seem to work.
If OCD Remote does not wotk with USB/Parallel converter I do not see an
affordable solution.
I am almost thinking it is worth the effort to build my own networked ARM7
RDI JTAG debugger pod (using the RDI interface provided by GDB and one of
the JTAG ARM7 projects from sourceforge).
Has anyone got experience with RDI or using the JTAG/EmbeddedICE combination?
I have a 2138 board with ethernet controller and TCP/IP software. Using
one of the sourceforge bitbang projects for ARM7 I could attach this to my
lpc21xx target board.
I'm just not a JTAG/EmbeddedICE expert so I have just a rough view of
what
I am up to. But I do know my way around the ARM (over 6 years of
experience with ARM7/9/10/11 embedded programming) and ARM assembly is
almost like a second language to me (although I keep struggling with the
syntax of the Gnu assembler).
If this works I could try to get a company to build the hardware for this
(price around 100 Euro). Software is all free.
Would be a great and fairly cheap debugging solution for use at school or
home.
Anyone interested in joining? or is this a stupid thing to try?

Have a look at:
www.mpeforth.com/usbstamp.htm
www.mpeforth.com/jtagwidget.htm
The CPLD on the USB Stamp is already configured as a JTAG host.
The software on the JTAG Widget is a scriptable ARM JTAG
debugger and Flash programmer with integral ARM assembler and
disassembler.
If you understand the RDI specs, doing what you want should be
straightforward.

I really doubt that you will have much luck finding a USB-parallel
adapter that will work with a Wiggler or clone, at least I have not
found one in my own searches. Does your laptop have a PCMCIA slot
available? The Quatech SPP-100 EPP Parallel PCMCIA card is claimed to
be fully compatible with anything requiring an EPP or stardard PC
parallel port. Here is one place that you can see info about them.

Whats the point of this link, as the products are not yet available.
Is it just a sales pitch, or am I being cynical
