Problem building PX4 1.12 for Durandal

I am trying to build the PX4 fro Durandal usnig last release sourcecode. (I did build for other platforms wirthout problems)
During The building process of PX4 firmware for holybro durandal
make holybro_durandal-v1_default
you also build the bootloader_firmware.
then you get an error during the building step
*[1296/1320] Performing build step for ‘bootloader_firmware’

At the opposite if you build the bootloader using the command :
make px4_fmu-v6x_bootloader
which is the same prcocess everything goes OK, there is no problem with libapps .

Can someone help ?


This problem is caused by limitation of filenames length (143) on WIN10 + cygwin…
Solution : rename the platform as durandal_v1 (instead of holybro_durnadal_v1)
