I've just purchased ardupilot mega v1.4 and arduIMU v2 flat. For now I've connected ardupilot to my own ftdi cable which based on ft232rl chip. Many of my projects were tested using that one. But for arduino I had to solder CTS and DTR wires and good to go....
I've flashed servo dance primer inside AP few times, after that I've tried to flash ardupilot mega 1.0Beta version but it said that something wrong with flashing eeprom. And after that I can't upload anything at all. When I use serial monitor - I see ardupilot CLI is there, but when I type, let's say, 'help' it echoes 'hAp' or 'hap', but not 'help'. Then I used codevision avr terminal program - works perfect - whats send thats received. Tried to run arduino on 2 systems - win7 x64 and win xp sp3. Any help greatly appreciated!
here is the errors that arduino gets:
avrdude: stk500_getsync(): not in sync: resp=0x00
avrdude: stk500_disable(): protocol error, expect=0x14, resp=0xfd
P.S. Yes, I did check 'set RTS line'
