5.5 Board configuration file values
The following fields are in the board_info array. These are
set by the set_board_info procedure (or add_board_info
procedure for appending to lists). Both procedures take a field name
and a value for the field (or is added to the field), respectively.
Some common board info fields are shown below.
Field Example value Description
compiler [find_gcc] The path to the compiler to use.
cflags -mca Compilation flags for the compiler.
ldflags [libgloss_link_flags] [newlib_link_flags] Linking flags for the compiler.
ldscript -Wl,-Tidt.ld The linker script to use when cross compiling.
libs -lgcc Any additional libraries to link in.
shell_prompt cygmon> The command prompt of the remote shell.
hex_startaddr 0xa0020000 The Starting address as a string.
start_addr 0xa0008000 The starting address as a value.
startaddr a0020000
exit_statuses_bad 1 Whether there is an accurate exit status.
reboot_delay 10 The delay between power off and power on.
unreliable 1 Whether communication with the board is unreliable.
sim [find_sim] The path to the simulator to use.
objcopy $tempfil The path to the objcopy program.
support_libs ${prefix_dir}/i386-coff/ Support libraries needed for cross compiling.
addl_link_flags -N Additional link flags, rarely used.
remotedir /tmp/runtest.[pid] Directory on the remote target in which executables are downloaded and executed.
These fields are used by the GCC and GDB tests, and are mostly only
useful to somewhat trying to debug a new board file for one of these
tools. Many of these are used only by a few testcases, and their
purpose is esoteric. These are listed with sample values as a guide
to better guessing if you need to change any of these.
