@Abhigkar
@Gordon so what will be the Make file command to create DFU package
When I use this command
make clean &&
NRF_SDK11=1
DFU_UPDATE_BUILD=1
BOARD=
RELEASE=1
USE_BOOTLADER=1
VERBOSE=1 make
and in BOARD.PY I have set
'bootloader' : 1,
It generates the DFU package just having Espruino application hex. The hex works perfect with a device which already have a valid bootloader installed.
