Tips for starting a board bring-up and debugging it

Hi

I hav just received the manufactured board with all components mounted. Now I need to start the board bring-up and debugging but I have no idea about it. I request you to please forward me some document related to this to which I can read and can do board bring-up.

I have BDI2000 high speed JTAG interface device.

Please help.

Thanks

I found this, maybe it is what you are looking for

There is a link to "Manuals", that it have a lot of information.

Board bring-up

Unless you tell us more about your board, probably nobody can help you.

Re: Board bring-up

yeah,post your schematics & its application here,someone will sure enlighten you on that,by step by step testing procedures

Board bring-up

there are some general things, like:

1. check if the components are with correct polarity (visual check)
2.check the solderings with a stereo optical microscope (20x-40x magnification), especially on the fine-pitch IC pins. and fix with soldering iron
3. measure short-circuits with a multimeter on all of the power rails. (some cpu cores seem to be short circ, but they are not)
4. connect a lab-power supply with current limit, and measure the current. turn on for a short time and check if the current is normal/abnormal.
5. check crystals and oscillators with a scope. (sine wave should be on crystal pins)
6.check buses with scope, if there is a traffic. especially those buses what are involved in boot.
7. any further depends on your system/board architecture.

go to next step only if theere is no error on the previous step.
