STK500 ISP Mode Error

2007-09-06 by Bruce

I like working with the AVRs, but just do it for fun.   Lately, I have 
been having a problem.

When I connect to the AVR Programer, select the Fuses or Lockbits tabs, 
I get the error:

"ISP Mode Error "   

I have check to make sure that on the Board tab,  that the ISP freq is 
less than 1/4 of the target clock.
STK500 Osc = 1.843 MHZ and ISP Freq = 3.998 KHZ. 

I can actually program the chip, ( AVR 1200 - 12, Also same using 2313 - 
10 ).   I  can not access the Fuses or Lockbits, which I think  prevents 
me from using the internal Oscillator.   This use to work.  When I 
select Fuses, all selection are grayed out and have a small red "?" 
mark.    Under Lockbits, "Mode 1 is checked, but has a small red "?", as 
does mode 2 and 3.    Smart Warning and Auto Verify are checked by 
default.  

What gives ?  

Other Facts.   This problem was also under AVR 4.x, upgraded to v 4.13.  
No change.   Jumpers Vtarget, Aref, Reset, Xtal 1 are all ON.   OscSel 
set to 2,3.  All other jumpers are off.  

If more info is needed, please ask. 

Thanks
Bruce
