I do not think that you will save many bits tweaking the RedBoot's sources.
First try to decrease number of RAM rooms with CDL
cdl_option CYGDBG_HAL_CRCTABLE_LOCATION {
user_value ROM
};
If you export the above it will save 1K of RAM.
If you can live without command line editing and history you can save ~
4K
CYGPKG_REDBOOT_MAX_CMD_LINE (255) x CYGNUM_REDBOOT_CMD_LINE_EDITING (16)
cdl_option CYGNUM_REDBOOT_CMD_LINE_EDITING {
user_value 0
};
cdl_option CYGBLD_REDBOOT_CMD_LINE_HISTORY {
user_value 0
};
If you can live without some RedBoot features, check all such options
CYGBLD_BUILD_REDBOOT_WITH_.*
and tune them. Etc.
At the end build a map file (add -Wl,-Map,mapfile to
CYGBLD_GLOBAL_LDFLAGS) and dive into it.
If you will continue to look for a few bytes, perhaps, you need another
bootstrap and debug environment for your target.
