Hi all,
I am trying to reduce the firmware size for cc2650 following the instructions on https://github.com/contiki-os/contiki/wiki/Reducing-Contiki-OS-firmware-size <https://github.com/contiki-os/contiki/wiki/Reducing-Contiki-OS-firmware-size>, as cc2650 has a maximum size of 128 KB Flash memory. However,after change Makefile and project-conf.h, it has no effect when building the hello-world example, the size of hello-world.srf06-cc26xx is still 192 KB.
Michael-WS-Yees-MacBook-Pro:hello-world michael$ cat Makefile
DEFINES+=PROJECT_CONF_H=\"project-conf.h\"
CONTIKI_PROJECT = hello-world
all: $(CONTIKI_PROJECT)
CONTIKI_NO_NET = 1
CONTIKI = ../..
include $(CONTIKI)/Makefile.include

Michael-WS-Yees-MacBook-Pro:hello-world michael$ cat project-conf.h
