Hi Les,
A couple of thing to try
- Check hat the ISP freq is < 1/4 Xtal freq (Under 'Board' Tab the ISP freq
combo box)\
- in the 'advanced' tab try to read the signature bytes (does not solve
anything but interesting..
- Try to manual erase the device (in 'Program' tab) before trying to
program flash (this resets the fuses as well)
An the some 'simple' ones (Ok, sorry to insult you ;-) ) but ...
- in the 'Program' tab - check that the 'Programming mode' settings are
- 'Erase Device before programming' checkbox set
- 'ISP' checkbox set
HTH
Ivan
