Hello,
We use slightly modified rboot
and we would like to define preprocessor variable used in rboot.c
during firmware building.
We have tried to modify rboot.mk
and add CFLAGS += -DFOO=${FOO}
and run mos tool as FOO=\"bar\" mos build ...
but it says:
rboot.mk:63: warning: undefined variable 'FOO'
It would be even better if we could use build_vars
for this.
Is it possible?
