I didn't use the board for a long time and I want to reuse it.
I tried updating the firmware via the latest mission planner, but couldn't succeed.
I tried updating to AC 2.2 (which seems to be uploading fine) but I couldnt get the mission planner to connect to the board.
Where can I find the latest working firmware that fits the above board? and can I upload it via mission planner or do I have to install IDE? and are there any known problems with the APM1 connection to the mission planner?
