# Application number and version info are included in the ELF file
# symbol table through two global, asbolute symbols. Use nm(1) on an
# ELF file to figure things out. Example:
# nm cc20rng.elf | awk '/VERSION/{print $1}'
# Application number:
# - cc20rng: 01
# - entropy: 02
APPLICATION = 0x00000001
# Version info is four octects, from most significant to least:
# - Major version, two bytes: 00..FFFF
# - Minor version, one byte: 00..FF
# - Patch level, one byte: 00..FF
VERSION = 0x00010000
# put your *.o targets here, make should handle the rest!
