I WANT TO KNOW WHETHER IT IS POSSIBLE TO TROUBLESHOOT A MICROPROCESSOR BASED SYSTEM WHERE ALL THE "IC ARE SOLDERED"
WITHOUT USING A LOGIC ANALYSER.IF IT IS POSSIBLE PLEASE SUGGEST ME THAT METHOD. :?:
Yes, the question is so vague as to be meaningless?.
You don't need a logic analyser, and one may not even be terribly helpful, but you do really need access to the source code of the processor - unless you know EXACTLY how it's supposed to work.
You don't even give any idea if this has ever worked?, or if it's a new design you're trying to make work?.
