I searched the forum, found other 'failure to launch' posts but they did not relate to my problem.
I can build and download to a Mega8 with no problems, it runs the code I expect ( test stuff, flash ports, use IRQ's to flash ports ) but when I select the STK500 for the simulator I get the "failure to launch" message - says "ERROR: An error occured when executing command with ID 0x11, time out waiting for a response, 68 characters was discarded while waiting for response start stoken" Their spelling, not mine.
Have I missed some sort of time out parameter that needs set in studio somewhere?
Thanks!

That makes no sense. Did you mean "select the mega8 for the simulator"?
The simulator is a software simulation of an AVR chip - it has nothing to do with programmers such as the STK500. |

| Um ... maybe I do not understand .. I can select the STK500 as the programmer/simulator in the build tools and I assumed that I debug using that. I take it that it is not an option even though I can select it? |

No to do on chip debugging you need to buy an interface from Atmel that is capable of doing such debugging. The STK500 is not. It is just a (very capable!) programmer.
So your debug options are either printf/LED/whatever in the code or to use a PC simulation of the AVR (but sadly not all the surrounding electronics).
If you want true on chip debugging switch to a mega88PA and pay $50 to buy a Dragon. |
