Problem in Installing the Custom Build Firmware

Hi Everyone,

I hope you are all doing great. I have set up the build environment using the steps given on wiki and successfully built the firmware.

I have also the secure firmware after following the instruction given on wiki

I have few queries, I hope somebody can answer these:

  1. How can I put my Pixhawk6C or Cube into DFU mode for flashing the custom build firmware?

    I have read here that ground station should be able to put the board into DFU, how can I do that?

I have tried to upload directly the build firmware using this command: ```
./waf copter --upload
But it shows this error:


I have connected the Pixhawk6C via USB.

Really looking forward to your help.
Thanks!

Can anybody please point me to a blog or some discussion where I can find out the steps of installing custom bootloader and firmware in the pixhawk cube?

I have checked this Wiki Page but still have a confusion.

I want to know is there any way through which I can upload the bootloader in the cube without opening the cube and pulling the “boot0” pin high on the processor.

Thanks! Really looking forward to someone help and response.
