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.
