It was tested being merged with OP-472_CorvusCorax_CopterControl-Guidance_v3
branch, Spektrum on USART3 and GPS on USART1 and seems to work.
Currently defaults mimic original behavior, that is, if USE_SPEKTRUM
is not defined - define USE_PWM and USE_GPS. Thsi should be refactored
later to make it configurable from the Makefile.
Also it was not ported to the OP MB: it currently does not support the
S.Bus hardware and still has original behavior with the patch. But this
is one more step to dynamic configuration of ports.
matches. Read the flash first bytewise to compute CRC instead of buffering
which is more RAM efficient but very inefficient as it sets up many one byte
SPI transfers.
Also incremented the filesystem magic flag to trigger an automatic flash wipe
on this upgrade.
- only affect flight/PiOS (no change for posix and win32)
- tested on recent master (some runtime on CC with GCS)
- the new timer feature is not compiled-in since we don't use it yet.
- NO TEST FLIGHT
The pipxtreme boards use a sector of the on-board flash
for configuration storage. Adjust the memory maps to
reflect this.
The board_info_blob is also extended to include the EE
bank definitions. This should be used by the pipxtreme
firmware rather than determining it based on chip size.
Now that every bootloader build has a board info blob,
make all fw and bl images use it.
The following MACROS are removed:
BOARD_TYPE, BOARD_REVISION, BOOTLOADER_VERSION,
START_OF_USER_CODE, HW_TYPE
These values are now ONLY available from the bootloader
flash via the pios_board_info_blob symbol. These values
must not be #defined or otherwise hard-coded into the
firmware in any way. The bootloader flash is the only
valid source for this information.
NOTE: To ensure that we have an upgrade path from an
old bootloader (without board_info_blob) to a
new bootloader (with board_info_blob), it is
essential that the bu_* targets do not depend
on (or validate) the board_info_blob being present
in the bootloader flash.
The USE_BOOTLOADER compile flag was only being used
to determine where the ISR vector table was located.
Provide this explicitly from the linker since it knows
exactly where it is putting the ISR vector table.
- New macros for fw, bl and bu rules in top-level make
- Per-board info factored into make/board/*/board-info.mk
- Per-board info now shared btw. fw, bl and blupd for each board
- BOARD_TYPE, BOARD_REVISION, BOOTLOADER_VERSION, HW_TYPE
- MCU, CHIP, BOARD, MODEL, MODEL_SUFFIX
- START_OF_BL_CODE, START_OF_FW_CODE
- blupd_* goals renamed to bu_*
- all_blupd goal renamed to all_bu
- firmware goals renamed to fw_*, board name goals are preserved
- bu_*_program now writes updater to correct address for all boards
- BL updater firmware builds now produce .opf format including
version info blob.
- BL updater firmware name now includes board name.
- INS makefile brought up to date w.r.t. linker scripts
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 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.
AHRS_comms still needs to be implemented. INS/GPS functionality still needs to be implemented. Double-check of the new drivers still needs to be done.
