Interrupts - nagarkarajay - Aug 20 0:41:06 2008
Hello,
I am using an MSP430FE425 processor for a project. I have some
software written that generates a watchdog timer interrupt every so
often , a Basic timer interrupt and an ESP Engine interrupt. I am able
to make this board work on one board but not on the other two. The
hardware configuration of these three boards is the same.
Has anybody seen the same code give interrupts properly on one board
and not on the other. Would anyone be able to suggest any possible
reasons for the same.
I am using the FET Real time Dubugger and Programmer
Thanks
Ajay

There are many possible causes of this kind of inconsistency. To name
a few:
(a) The seemingly identical hardware is not really identical.
(b) Certain aspect of your code or hardware is outside specified
range. (For example, the clock frequency is too high for the Vcc used.)
(c) Your code depends on initial conditions that varies from chip to
chip. (For example, the content of SP.)

Thanks !!
The seemingly identical hardware was not identical. Thanks to the PCB manufacturer there was an unwanted trace between the XIN and Gnd.
