This allows the spektrum and sbus receiver drivers to bind
directly to the usart layer using a properly exported API
rather than overriding the interrupt handler.
Bytes are now pushed directly from the usart layer into the
com layer without any buffering. The com layer performs all
of the buffering.
A further benefit from this approach is that we can put all
blocking/non-blocking behaviour into the COM layer and not
in the underlying drivers.
Misc related changes:
- Remove obsolete .handler field from irq configs
- Adapt all users of PIOS_COM_* functions to new API
- Fixup callers of PIOS_USB_HID_Init()
The initial baud rates of each interface are now forced in the
board init code.
Any modules using USARTs should have fields added to
their settings object to allow the user to change the
baud rate from the default by using the COM layer APIs.
Developers requiring custom baud rates before the settings
objects are in place should locally edit the cfg structs
to specify the desired baud rates.
This should mark an end to the compile-time selection of HW
configurations.
Minor changes in board initialization for all platforms:
- Most config structs are marked static to prevent badly written
drivers from directly referring to config data.
- Adapt to changes in .irq fields in config data.
- Adapt to changes in USART IRQ handling.
Major changes in board initialization for CC:
- Use HwSettings UAVObj to decide which drivers to attach to
the "main" port and the flexi port, and select the appropriate
device configuration data.
- HwSettings allows choosing between Disabled, Telemetry, SBUS,
Spektrum,GPS, and I2C for each of the two ports.
- Use ManualControlSettings.InputMode to init/configure the
appropriate receiver module, and register its available rx channels
with the PIOS_RCVR layer. Can choose between PWM, Spektrum and PPM
at board init time. PPM driver is broken, and SBUS will work once
it is added to this UAVObj as an option.
- CC build now includes code for SBUS, Spektrum and PWM receivers in
every firmware image.
PIOS_USART driver:
- Now handles its own low-level IRQs internally
- If NULL upper-level IRQ handler is bound in at board init time
then rx/tx is satisfied by internal PIOS_USART buffered IO routines
which are (typically) attached to the COM layer.
- If an alternate upper-level IRQ handler is bound in at board init
then that handler is called and expected to clear down the USART
IRQ sources. This is used by Spektrum and SBUS drivers.
PIOS_SBUS and PIOS_SPEKTRUM drivers:
- Improved data/API hiding
- No longer assume they know where their config data is stored which
allows for boot-time alternate configurations for the driver.
- Now registers an upper-level IRQ handlerwith the USART layer to
decouple the driver from which USART it is actually attached to.
Macros for JTAG program and wipe for each target are now
provided in firmware-defs.mk.
The _wipe target for each firmware and bootloader image will
erase either the bootloader (bl_*_wipe) or firmware (fw_*_wipe)
bank.
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
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.
The .bin.o rule places the contents of a raw .bin file
into an .o file wrapped within fixed symbols for start
and end. This can be used to embed a binary file inside
of an executable.
The symbols for the embedded binary blob are:
_binary_start
_binary_end
_binary_size
NOTE: The way the .bin.o rule is currently written, you
can only embed one binary blob in an executable since the
symbol names will collide if you add multiple blobs. This
limitation is easily removed later if necessary.
Also change AttitudeActual to update at 10Hz rather than 2 Hz. The increased bandwidth is minimal and the resulting "polish" that it adds to the look-and-feel of the GCS is signifcant.
firmware include and delete all the extra foss-jtag config files. There is now

This significantly reduces the amount of duplication
across the various firmware makefiles.
The new firmware-defs.mk file should contain only
macros/declarations that will apply to all firmware
makefiles.

data. I don't like this but because of the way the calibration routine works
(sets all gains to 1) this makes the values so far out or range the EKF doesn't
get to run and the mag wasn't previously being updated.

Not yet used anywhere but will eventually allow
debug pins to be assigned during runtime init based
on configuration found in a new uavobject.
