Damien George e2def200bf stm32/boards/PYBD_SF2: Put BTstack library in external QSPI XIP flash.
In the same way the nimble stack is put there.

Damien George 51f8591097 stm32/boards/PYBD: Allow building with BTstack (via make command line).
Work done in collaboration with Jim Mussared aka @jimmo.

Damien George 69661f3343 all: Reformat C and Python source code with tools/codeformat.py.
This is run with uncrustify 0.70.1, and black 19.10b0.

Damien George e3187b052f stm32/boards/PYBD: Change RTC asynch prediv from 1 to 4.
This change has the following effects:
- Reduces the resolution of the RTC sub-second counter from 30.52us to
  122.07us.
- Allows RTC.calibration() to now support positive values (as well as
  negative values).
- Reduces VBAT current consumption in standby mode by a small amount.

For general purpose use 122us resolution of the sub-second counter is
good enough, and the benefits of full range calibration and minor reduction
in VBAT consumption are worth the change.

Damien George fb01415599 stm32/boards/PYBD_SF2: Configure LEDs as inverted, for LED.intensity(). 2019-12-13 17:28:24 +11:00
Damien George 120368ba1a stm32/boards: Enable LFS2 on PYBv1.x and PYBD boards. 2019-11-26 00:08:57 +11:00
Damien George 4a6974bea5 stm32/boards/PYBD_SF2: Put nimble library in external QSPI XIP flash.
The BLE stack is not performance critical, so put it in external
memory-mapped flash to save internal flash for other things (like frozen
bytecode).

Damien George b1e04848ef stm32/mphalport: Put PYBD specific MAC code in board specific file. 2019-08-28 12:37:13 +10:00
Damien George c1a8c7fc09 stm32/boards/PYBD_SFx: Automatically turn on EN_3V3 when powering SD/MMC 2019-07-04 11:11:11 +10:00
Damien George 1cd2bc066d stm32/boards/PYBD_SFx: Configure EN_3V3 pin as output on boot.
But leave it turned off, the application must turn it on if/when needed.

Damien George 3581deec81 stm32/boards/PYBD_SF2: Put mbedtls library code in external QSPI flash.
mbedtls is large and self contained so is a good candidate to be in
external XIP flash, to keep enough spare ROM in internal flash.

Damien George d821a27b58 stm32/boards/PYBD_SFx: Put SPI flash to sleep during sleep modes. 2019-07-03 01:27:33 +10:00
Damien George 009b1f6559 stm32/boards: Rework all stm32??xx_hal_conf.h files to use common code.
This eliminates a lot of duplicated code in these header files.

Damien George 04c7cdb668 stm32: Enter bootloader via a system reset.
Entering a bootloader (ST system bootloader, or custom mboot) from software
by directly branching to it is not reliable, and the reliability of it
working can depend on the peripherals that were enabled by the application
code.  It's also not possible to branch to a bootloader if the WDT is
enabled (unless the bootloader has specific provisions to feed the WDT).

This patch changes the way a bootloader is entered from software by first
doing a complete system reset, then branching to the desired bootloader
early on in the start-up process.  The top two words of RAM (of the stack)
are reserved to store flags indicating that the bootloader should be
entered after a reset.

Chris Mason 14cf91f704 stm32: In link script, define start of stack separately from heap end.
Previously the end of the heap was the start (lowest address) of the stack.
With the changes in this commit these addresses are now independent,
allowing a board to place the heap and stack in separate locations.
