Andrew Leech ce0c581179 stm32/main: Add board config option to enable/disable mounting SD card.
The new option MICROPY_HW_SDCARD_MOUNT_AT_BOOT can now be defined to 0 in
mpconfigboard.h to allow SD hardware to be enabled but not auto-mounted at
boot.  This feature is enabled by default to retain previous behaviour.

Previously, if an SD card is enabled in hardware it is also used to boot
from.  While this can be disabled with a SKIPSD file on internal flash,
this wont be available at first boot or if the internal flash gets
corrupted.

Andrew Leech 338635ccc6 stm32/main: Add configuration macros for board to set heap start/end.
The macros are MICROPY_HEAP_START and MICROPY_HEAP_END, and if not defined
by a board then the default values will be used (maximum heap from SRAM as
defined by linker symbols).

As part of this commit the SDRAM initialisation is moved to much earlier in
main() to potentially make it available to other peripherals and avoid
re-initialisation on soft-reboot.  On boards with SDRAM enabled the heap
has been set to use that.

Damien George ea7e747979 stm32: Add support for STM32F0 MCUs. 2018-05-28 21:49:49 +10:00
Damien George f497723802 stm32: Allow to have no storage support if there are no block devices.
If no block devices are defined by a board then storage support will be
disabled.  This means there is no filesystem provided by either the
internal flash or external SPI flash.  But the VFS system can still be
enabled and filesystems provided on external devices like an SD card.

Ryan Shaw b9ff46f1ed stm32: Enable UART7/8 on F4 series that have these peripherals. 2018-05-16 11:55:07 +10:00
Damien George 92c5e2708d stm32/modpyb: Introduce MICROPY_PY_PYB_LEGACY config option for pyb mod.
This is enabled by default.  When it is disabled all legacy functions and
classes in the pyb module are excluded from the build.

Damien George 8a949ba599 stm32: Introduce MICROPY_PY_STM config to include or not the stm module.
By default the stm module is included in the build, but a board can now
define MICROPY_PY_STM to 0 to not include this module.  This reduces the
firmware by about 7k.

Damien George 3d5d76fb73 stm32/main: Allow a board to configure the label of the flash FS.
To change the default label a board should define:

    #define MICROPY_HW_FLASH_FS_LABEL "label"

Damien George cf9fc7346d stm32: Allow a board to configure the HSE in bypass mode.
To use HSE bypass mode the board should define:

    #define MICROPY_HW_CLK_USE_BYPASS (1)

If this is not defined, or is defined to 0, then HSE oscillator mode is
used.

Damien George a7ebac2eae stm32/can: Allow CAN pins to be configured per board.
This patch allows a given board to configure which pins are used for the
CAN peripherals, in a similar way to all the other bus peripherals (I2C,
UART, SPI).  To enable CAN on a board the mpconfigboard.h file should
define (for example):

    #define MICROPY_HW_CAN1_TX (pin_B9)
    #define MICROPY_HW_CAN1_RX (pin_B8)
    #define MICROPY_HW_CAN2_TX (pin_B13)
    #define MICROPY_HW_CAN2_RX (pin_B12)

And the board config file should no longer define MICROPY_HW_ENABLE_CAN.

Damien George b833f170c3 stm32/main: Only update reset_mode if board doesn't use a bootloader.
If the board is configured to use a bootloader then that bootloader will
pass through the reset_mode.

Damien George 626d6c9756 stm32/storage: Introduce MICROPY_HW_ENABLE_INTERNAL_FLASH_STORAGE cfg.
This config variable controls whether to support storage on the internal
flash of the MCU.  It is enabled by default and should be explicitly
disabled by boards that don't want internal flash storage.

iabdalkader 61d463ad07 stm32/mpconfigboard_common: Add STM32H7 common configuration. 2018-03-09 15:12:44 +11:00
Damien George 989fc16162 stm32: Move MCU-specific cfg from mphalport.h to mpconfigboard_common.h.
It's cleaner to have all the MCU-specific configuration in one location,
not least to help with adding support for a new MCU series.

Damien George 60b0982bb2 stm32: Add board config option to enable/disable the ADC.
The new option is MICROPY_HW_ENABLE_ADC and is enabled by default.

Damien George 5c320bd0b0 stm32: Introduce MICROPY_HW_ENABLE_USB and clean up USB config.
This patch allows to completely compile-out support for USB, and no-USB is
now the default.  If a board wants to enable USB it should define:

    #define MICROPY_HW_ENABLE_USB (1)

And then one or more of the following to select the USB PHY:

    #define MICROPY_HW_USB_FS (1)
    #define MICROPY_HW_USB_HS (1)
    #define MICROPY_HW_USB_HS_IN_FS (1)

Damien George 2d5bab46be stm32: Add mpconfigboard_common.h with common/default board settings.
This file mirrors py/mpconfig.h but for board-level config options.  It
provides a default configuration, to be overridden by a specific
mpconfigboard.h file, as well as setting up certain macros to automatically
configure a board.
