I showed 3 points where you can get access to the important datalines, besides the obvious connectionport (that would be number 4:)).Ħ.
Note: I labeled RX and TX relative to the GPS not the CPU (like printed on the PCB). Look at this picture for the right connection: If you have not the right plug (like me) you have some solder pads right behind it. If FTDI connection is already established, powercycle to reset GPS to its' default state.ĥ. You can also use the precompiled hex from my post here: Ĥ. It won't work with the arduino still talking on the serial line - i tested it.
Do Arduino / eeprom clear on your main CPU so that no serial traffic can disturb the process. Load MP and save all your parameters to a file (if desired).ģ. Download the zip below to have all the files needed - and a flashguide.Ģ. It contains basically the same files than the previous version but an extended guide and the source code.įTDI Hardwareflash on APM 2.0 (Set your FTDI to 5V, if you have one of these Breakoutboards)ġ. I included a zip file with all the needed files and a complete guide below. Since the gps is directly mounted to the mainboard i don't know how to do it. I am currently messing around with MTK GPS stuff and the binary protocol.Īssuming my APM2.0 GPS has the 1.6 loaded, i want to upgrade the GPS FW. Posted by Crashpilot1000 on Decemat 1:45pm
