CC and CC3D boards share the same FW image. This is accomplished
by checking the BOARD_REVISION field in the board_info_blob
that is stored in the BL partition in flash as we init the FW.
Make sure that the BU image only writes a BL image that has
the same BOARD_TYPE and BOARD_REVISION fields in the embedded
image as the ones currently in flash on the board.
This ensures that we never write a CC3D BL image onto a CC board
and vice versa. This check should prevent "bricking" a board.
Use new PIOS_USB_UTIL_AsciiToUtf8() function to compose the
USB serial number rather than repeating that code for each
board.
All boards now append "+FW" or "+BL" to their USB serial numbers
to allow the descriptors to differ between FW and BL images.
Some versions of Windows will ignore the USB device serial number
if the string is not delivered with LANGID = English US 0x0409.
This is true regardless of the configured locale of the machine.
The serial number string descriptor was incorrectly null
terminated. The standard clearly states that there should
not be a null terminator.
Use new #defines to ensure that our strings are sized
properly.
BL images now always use hid-only.
FW images can use hid-only or hid+vcp but this is selected
ONLY at compile time based on whether PIOS_INCLUDE_USB_CDC
is defined.
CC uses HID+VCP by default now.
This makes the BL and FW images distinct devices with unique
serial numbers.
Windows (and maybe Mac) remembers the device descriptors and
the associated drivers based on this serial number. Providing
unique serial numbers for the BL and FW images allows us to
provide different sets of descriptors for the BL and FW images
without confusing these OSes.
BL version number is now also bumped to reflect the new
serial number generation algorithm.
Now that we have a USB descriptor for HID+VCP that works
on Ubuntu 11.10, MacOS 10.7.3, Win7-SP1-32bit,
WinXP-SP3-32bit, Win7-SP1-64bit.
VCP is known to not work on WinXP without service pack 3.
hardware revision it cannot know which pios_led_cfg_ structure to use.
Possibly this should be abstracted further into board_hw_defs to create
functions like board_init_led.
Also the BU should probably compare the hw_revision of the original and new
bootloader to make sure the user doesn't break their board.
Bootloader updaters were all broken due to recent
changes in LED configuration handling. Removing
LED support from the BU loads allows them to build
again, but they provide no feedback about when they're
finished writing flash.
The code in RCC_GetClocksFreq() uses HSE_VALUE to determine
the tick rate of the SYSCLK. This in turn is used by the
code in PIOS_DELAY_* to compute delays.
ST Library defaults this to 25MHz for the F4. Our board
actually has an 8MHz oscillator so delays were way off.
Mostly affects the bootloaders since most FW code uses RTOS
delays rather than busy-waiting using PIOS_DELAY_*.
Removes hard-coding of JTAG interface config in the
<board>_program make macros.
This allows the use of STLINKv2 for F4 boards while
continuing to use the FOSS JTAG revB on F1 boards.
for sensing and then load different config for CC and CC3D. Updated the
bootloader as well. Also changed the PIOS_USB_CheckAvailability function to
only return the sense signal and not the transfer_possible flag as this is not
set in time for the bootloader on CC3D for some reason.
Board specific HW configuration is now collected in a single .c
file for each board. This HW configuration is #include'd into
the FW, BL and BU builds for each board.
These new .c files are found in:
flight/board_hw_defs/<board_name>/board_hw_defs.c
Parts of this information were previously duplicated between
the BL and FW builds. This commit cleans up the duplication.
Using a #include on a .c file is a bit ugly but it allows us
to ensure that all of the symbols in the board_hw_defs.c file
are *ONLY* used in the PIOS_Board_Init() function for each
software build.
The main purpose of this new COM implementation is that it is
much simpler, and requires less code space. This takes a bit
of the pressure off of the CC bootloader which was right at
the limit of available code space in the bootloader partition.
This is not intended to ever be used by the application.
This driver also formalizes the assumptions in the bootloader's
usage of the COM layer. All messages are assumed to arrive
in atomic chunks from the HID layer.
This can be used by the GCS firmware uploader widget to boot
the firmware with a (temporarily) defaulted hwsettings uavo
so that a user can easily recover from a bad/incompatible
hwsettings configuration without wiping all settings.
This uses the same mechanism that the BootFault auto-recovery
code already uses in the CC firmware. The auto-recovery is
triggered by setting the failed-boot counter to a maximum
value forcing recovery on the next FW init.
The PIOS_COM_ReceiveBufferUsed() function call is no longer
necessary since the same semantics can be achieved using calls
to PIOS_COM_ReceiveBuffer().
Summary of changes:
* USB CDC and HID drivers are completely split apart.
* This will allow different max buffer sizes for HID and CDC.
* USB descriptors have been overhauled:
* Proper structs/macros/enums declared for USB (see pios_usb_defs.h)
* Two common descriptor definitions. One for HID+CDC another for HID only.
See pios_usb_desc_{hid_cdc,hid_only}.c for details.
* Long standing bugs in OP USB descriptors became much more obvious with the
new struct definitions.
* Board specific USB initialization is now in pios_usb_board_data.h in each build target.
* Definition of USB descriptors is now entirely indpendent of STM32 libs.
Glue into STM32 libs is provided by pios_usbhook.c.
* Removed a lot of stale/irrelevant USB #defines throughout the tree.
* Improved naming consistency throughout USB code:
* PIOS_USB_HID_* now refers to the HID endpoint code.
* PIOS_USB_CDC_* now refers to the CDC endpoint code.
* PIOS_USB_* now refers to the low-level USB code.
* PIOS_USB_BOARD_* now refers to board-specific USB data
* PIOS_USBHOOK_* is glue between PIOS and STM32 USB libs.
* struct usb_* and enum usb_* and USB_* and HID_* are all types from the USB spec.
* Shrunk the buffer size on the CDC call mgmt endpoint to save some RAM.
* Made a few more USB related variables static to save some RAM.
Reduced scope of many variables since they were being
exposed unnecessarily.
Renamed pios_usb_hid_prop code to pios_usbhook to reflect
the fact that it implements all of the callout functions
that are hooked into the stm32 usb library.
