This does not affect the size of the image or the RAM
used by the firmware image. All debugging symbols are
stripped from the elf file during the conversion to a
.bin file.
The board info blob is stored in the last 128 bytes of the
bootloader's flash bank. You can access this data from the
application firmware like this:
#include <pios_board_info.h>
if (pios_board_info_blob.magic == PIOS_BOARD_INFO_BLOB_MAGIC) {
/* Check some other fields */
}
DO NOT link pios_board_info.c into your application firmware.
Only bootloaders should provide the content for the board info
structure. The application firmware is only a user of the data.
This is done by separating PyMite-dependent sources and making them
dependent on autogenerated python code. This was tested with make -j
on Windows and worked fine. It failed with errors otherwise:
In file included from ../Libraries/PyMite/vm/class.c:28:
../Libraries/PyMite/vm/pm.h:198: fatal error: pmfeatures.h: No such file or directory
This fixes the OP bootloader getting stuck in the
bootloader forever when USB is plugged in.
This also fails hard on being passed an unsupported
timer value so that this can be caught more easily
in the future.
This change is made up of a number of tightly coupled
changes:
- Deprecate the use of the USE_BOOTLOADER command-line
option. It is now hard-coded in each Makefile.
Overriding it on the command line is not allowed.
- Split apart the memory declaration and the section
declaration in all linker files (*_memory.ld and
*_sections.ld).
- Describe the split between bootloader and app sections
of flash in each board's _memory.ld file.
- Change program target to selectively erase flash so
that the installed bootloader is preserved across even
JTAG programming operations.
- All elf files are built with debug symbols and are not
stripped. This should help debugging with gdb. The
images programmed on the boards are all .bin files now
which do not include symbols.
New targets:
- make blupd_all_clean
- make blupd_all
- make blupd_openpilot
- make blupd_ahrs
- make blupd_coptercontrol
- make blupd_pipxtreme
These targets are also included in the 'all_flight' target.
