Issue with upload

I am currently having an issue during the build-upload process. I am following the “Building for Pixhawk/PX4 using Eclipse on Windows” instructions. The hardware target is a pixracer. I am using the “px4-v2-upload” command for the build. The build- upload process ends up hanging with the following message:

Loaded firmware for 9,0, size: 1023144 bytes, waiting for the bootloader…
If the board does not respond within 1-2 seconds, unplug and re-plug the USB connector.
attempting reboot on COM4…
if the board does not respond, unplug and re-plug the USB connector.

It hangs at this message indefinitely. I have tried unplugging and re-plugging the pixracer multiple times. The build progress reported by eclipse never gets past 0%. Any help that can be provided is greatly appreciated. Thanks!

When I built my firmware for Pixracer I uploaded it with Mission Planner.

I’m thinking its not finding your Pixracer during the upload. Do you have authority to use external devices?


Thank you for the reply. It turned out to be user error. I was using the px4-v2 build command when I should have been using the px4-v4 build command. However, I did end up using g MP to load the new build to the pixracer.

Thanks again!
