I am trying to figure out if the ATmega644A I purchased from EMSL can be programmed by my STK500?
The online STK500 user guide only lists the ATmega644 and ATmeag644P. But under the "Tools" section for the ATmega644A details page from the Atmel website it shows the STK500.
I know my STK500 is working correctly as I am able to read and write to my ATmega16 perfectly. But when I select ATmega644A in the drop down in the AtmelStudio Device Programming dialog, and try read the device signature it says;
Unable to enter programming mode. The read device ID does not match the selected device or any other supported devices.
Please verify device selection, interface settings, target power and connections to the target device.
Any suggestions welcome!
