Hello, I'm SeungWoo Park.
I'm using uav toolbox support pakcage for PX4 autopilot.
I flied quadcopter with pixhawk 4 using uav toolbox support package for autopilot PX4.
It did not faced any error with pixhawk 4.
And I wanted to use pixhawk orange cube. So I tried hardware setup process.
and I faced this problem.
In this step,
I clicked 'Build Firmware', and I saw this error although firmware build successful.

Is this normal? In command window, firmware build faced error.
but hardware setup showed firmware build successful...
I tried next step test connection - upload firmware, but it didn't work
What should I do??

If you are seeing the cube orange build failure with above error message, note that this issue is coming because of the limitation of length of filenames in Windows. cdcacm_main.cygdrive.c.px4_cygwin.home.Firmware.build.cubepilot_cubeorange_default.external.Build.bootloader_firmware.NuttX.apps.system.cdcacm.o has more characters in the filename than the maximum allowed number of characters in Windows. You can work around this problem by reducing the path length of the PX4 firmware. To workaround the issue
  • Option 1: Uninstall current Cygwin toolchain and install the Cygwin Toolchain to a shorter path such as C:/px4 instead of C:/px4_cygwin. Run hardware setup screens in MATLAB again with new Cygwin path
  • Option 2: You can also consider cloning the PX4 firmware to a shorter path like C:/mypx4 instead of cloning the px4 to C:/px4_cygwin/home
