I have a cheap Wriggler clone and evaluation board from Web7days. I (now) know that by paying a little bit more I could have got much better, and I will be getting some better tools. But, today I got back to ny LPC project and as the Web7days kit is all I have at the moment I resumed work with that. I get a lot of problems with the jtag I/F, and reasoned that it ain't that complicated....let's fix it. Armed with Leon Hellers scheme in the file section I found the problem in 2s flat.....pins 1 and 2 of the jtag connector on the evaluation board were connected together but to nothing else....the '244 on the wriggler had Vcc at 2V courtesy of the protection diodes. And this is the MKII version of the board! You get what you pay for.....I saved perhaps $30 by going to Web7days, the worse "saving" I have ever made in my life!
