Re: [lpc2000] Re: JTAG commands are secret?

As a commercial vendor, I am less interested in Open Source tools but I can 
wholeheartedly agree about low cost tools.  One "weakness" of our $199 ARM 
compiler is that there was no corresponding low cost flash programmer 
tools. I went around pitching to different vendors for licensing their 
technology. I told them that I don't need fancy stuff, just a simple way to 
burn as many different types of flash as possible. It's amazing the kind of 
deafening silence I get (I guess I am not much of a salesman). In the end, 
we did find someone and we are now shipping a PAR JTAG w/ Windows flash 
downloader for $175. More than I would like but still cheaper than other 
solutions. I am negotiating with another very famous JTAG maker to see if I 
can convince them for a lower cost (~$400-$500 *ouch I know* but it will be 
USB) solution.
