Custom firmware .px4 file reports no end flag when uploading #1132

Open ycai47 opened 8 years ago

ycai47 commented 8 years ago

I was trying to add IR Lock precision landing on my quadcopter and I followed http://dev.ardupilot.com/wiki/building-px4-with-make/ to make the .px4 file after I modified the APM_Config.h file to enable precise landing and build from master branch of ardupilot as suggested by this page, https://irlock.readme.io/docs/download-links. However, it keeps giving me an error like this:

The hex file does no contain an end flag

And then followed by:

Failed to read firmware.hex: No end flag in file

Is there anything that needs modified in Utilities/Firmware.cs or it is rooted somewhere else?

what other usb devices do you have plugged in? I would try unplugging other atmega devices and try again.

I tried unplugging everything, even restarting. I finally uploaded with APM Planner 2.0, so that's probably special about Mission Planner.

can you post your missionplanner.log file for when the error occurs. as for some reason something connected to your pc is being identified with a vid and pid of a apm2 style device.
