LPC2294/LPC2292, JTAG and any Hardware problem
2004-10-05 by kralikbo
Hi all. I have a problem with LPC2292/2294 device, please help me.I made system with LPC2294/2292 Philips processor.System contains CPU, 24MHz, xtal, two capacitors, JTAG EI012 interface, decouple capacitors for all supply pins(100nF) and supply devices(LM2941S, LP3961). When I connect system to PC, all well works, but LPC2292 and LPC2294 give me same ID code 0x9FF0F0F.I works with JTAG-tools. http://sourceforge.net/projects/jtagtools Next I changed supply device(high operating temperature of voltage regulator LP3961), something I must did wrong, becouse nothing works, oscilator did not work too. I changed CPU, JTAG not works.Oscilator work on 24MHz frequency, voltage on xtal is 1.515V, U3.3=3.26 V, U1.8=1.8V, power consumation is 20mA. First function prototype consumation about 200mA power. All pins and peripherials I check, all is OK. I don't have idea, what is worng. Tell me please any idea, how I find what is wrong. Thanks for all advices. BTW: I did not check system via ISP features, I must do it. http://www.geocities.com/kralikbo
