nrf connect sdk version :1.2.0
application:nrf_: desktop
I use command "west build -b nrf52840_pca20041 -d build_pca20041" , but it report error at last.
I don't know how to fix it.
And i compare my failure build_file with a success build_file ,i found the failure build_file lack several files ,such as: zephyr.hex , zephyr.bin and so on.
In addition, i can flash program by using success build_file.
