If the emulator works, then you've got to be close.  Things to check, in
order:

1  -  Make sure the emulator is working with target board power and clock.

With the real chip:

2  -  Do a VERIFY on the chip to make sure it's programmed correctly.

3  -  Check the oscillator mode and make sure the oscillator is oscillating.
Make sure you set the scope proble to high impedence.  A "normal" impedence
probe can kill crystal oscillations.

4  -  Check the power, and make sure you have brownout detect disabled if
using less than the normal 5 volts.
