I was playing with AVRStudio4.18 + STK500 plugin, and an AVRISP (v2 firmware in the original AVRISP, NOT AVRISP MkII), when I noticed that it displays incorrectly the ISP Frequency. The ISP frequency range in the pulldown should go from some 900kHz down to 600Hz, half of what is the range of STK500 (1.8Mhz downto 1.2kHz). IIRC older version of Studio displayed this correctly.
The stk500.exe command line tool displays the frequency correctly.
Anybody else who could confirm/reject my suspicion, or any previous post here (I did search found nothing) before I complain at Atmel?
