4.1.3 Connecting Atmel AVR Dragon to Atmel STK500
Atmel STK500 does not have a dedicated JTAG interface connector. To connect the Atmel AVR Dragon to the STK500 board, the JTAG Probe must be strapped to the appropriate JTAG Port Pins of the target device using a squid cable. Alternatively an STK500 JTAG adapter can be used, see section The STK500 JTAG adapter. Check the target device datasheet for the location of the JTAG pins on the appropriate device. The figure below shows an example on how the pins should be connected for an ATmega32 on the STK500. Remember to remove the reset jumper on the STK500 if the reset pin is going to be controlled from the AVR Dragon.
Add-on cards for the STK500 like e.g. STK501/502 may have a dedicated JTAG connector.
