Dear All, In one of the makefile souces, I saw the following statement. arm-elf-gcc util.c -o flutil -DFL_DATA=util_bin -DFL_IMAGE=util.bin -DFL_DATA_CKSUM=$FL_DATA_CKSUM I do not understand about the FL_DATA and FL_IMAGE macros that are passed in the above statement. Where can I get the information on these macros? Any idea / links, would be appreciated. Thanks and Regards, Madhavi M. _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
