I have been using the stk500 for a good while programming the atmega48. However about a week ago it began running VERY slowly...What used to take 15 seconds to program a device now takes about 2 minutes (whether chip on stk500 or using ISP & target PCB).
I happen to have a 2nd stk500 & simply swapping them out gives me my original high programming speed (using the same target board), Is there some sort of speed setup that is remembered in the STK500? I can't seem to find any "setups" to chage this. Both STK's have the same jumpers installed, only one is about 8 times faster than the other. What's wrong? Both are set to use the stk500 3.69 Mhz clock (but I don't think this would changed the ISP programming speed)
