Problems loading the code with Arduino IDE

I am trying to load APM 2.2 for an aircraft autopilot through APM Mission Planner but it keeps getting stuck on "Checking APM version". I am using a APM v1.0 blue board and also tried it on v1.0 red board - both with oilpan. So I cannot just try APM MP as suggested.

Just to confirm that everything is setup OK (cables, ports, board) I tried uploading the APM_RC sketch via Adruino IDE and that works well.

So I thought I would try compiling APM 2.2 via the Arduino IDE, it compiles OK but I get the same error as June at the begining of this thread namely:

Binary sketch size: 131608 bytes (of a 126976 byte maximum)

processing.app.debug.RunnerException: Sketch too big;

I followed Chris's instructions in the http://diydrones.com/profiles/blogs/getting-the-most-out-of-your to try and reduce the size but still get 131608 bytes. Also going through the code it appears that most code is already to set to only compile if required so size should already be less than the max for APM 1280.

From various posts it is stated that up to APM 2.3 it will remain compatible both with Mega 1280 and Mega 2560.

I really need help as totally stuck and badly need to get it working especially in HIL_XPLANE mode for some important tests.

Adrian, the Arduino code is meant for 2560 boards (Arduino adds code that pushes it over the memory limit, which the hex files in the Mission Planner do not). If you want to use it with the older 1280 board, you need to disable some features as described in this post:
