USAGE: ./build roms targetname
To build *all* boards, do this: ./build roms all
To list *all* boards, do this: ./build roms list
Optional Flags:
-d: displaymode
-p: payload
-k: keyboard layout
Example commands:
./build roms x60
./build roms x200_8mb x60
./build roms x60 -p grub -d corebootfb -k usqwerty
to see possible values for 'target':
./build roms list
Can also build serprog images:
${serprog_usage}
to see targets of only a given status (stable, unstable,
broken, untested and unknown), try e.g.
./build roms list stable
./build roms list unstable untested
./build roms list unknown
./build roms list broken
./build roms list broken stable
the value is set in target.cfg for each board. if status
is unitialised, it defaults to "unknown". only stable/unstable
targets are permitted in releases; broken, untested and
unknown are not allowed, but are accessible via normal building
Refer to the ${projectname} documentation for more information.
