Damien George 335d26b27d stm32/boards/STM32L476DISC: Update SPI flash config for cache change. 2018-06-14 16:52:56 +10:00
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 7e28212352 stm32/boards/STM32L476DISC: Update to not take the address of pin objs. 2018-03-28 16:29:55 +11:00
Damien George ed75b2655f stm32/Makefile: Allow a board to config either 1 or 2 firmware sections.
This patch forces a board to explicitly define TEXT1_ADDR in order to
split the firmware into two separate pieces.  Otherwise the default is now
to produce only a single continuous firmware image with all ISR, text and
data together.

Damien George 95b2cb008e stm32/Makefile: Rename FLASH_ADDR/TEXT_ADDR to TEXT0_ADDR/TEXT1_ADDR.
To make it clearer that these addresses are both for firmware text and that
they have a prescribed ordering.

Damien George 7aec06ca9a stm32/boards: Allow boards to have finer control over the linker script.
This patch allows a particular board to independently specify the linker
scripts for 1) the MCU memory layout; 2) how the different firmware
sections are arranged in memory.  Right now all boards follow the same
layout with two separate firmware section, one for the ISR and one for the
text and data.  This leaves room for storage (filesystem data) to live
between the firmware sections.

The idea with this patch is to accommodate boards that don't have internal
flash storage and only need to have one continuous firmware section.  Thus
the common.ld script is renamed to common_ifs.ld to make explicit that it
is used for cases where the board has internal flash storage.

Damien George 6b51eb22c8 stm32: Consolidate include of genhdr/pins.h to single location in pin.h.
genhdr/pins.h is an internal header file that defines all of the pin
objects and it's cleaner to have pin.h include it (where the struct's for
these objects are defined) rather than an explicit include by every user.

Damien George 22a9158ced stm32/boards/STM32L476DISC: Enable CAN peripheral.
This board allows to test CAN support on the L4 series.

Damien George bb3359f357 stm32/boards/STM32L476DISC: Provide SPI-flash bdev config.
This board shows how to configure external SPI flash as the main storage
medium.  It uses software SPI.

Damien George 34911f1a57 stm32/boards: Update all boards to work with new USB configuration. 2018-02-13 18:57:01 +11:00
Damien George 02f88cb2df stm32/boards: Remove all config options that are set to defaults.
mpconfigboard_common.h now sets the defaults so there is no longer a need
to explicitly list all configuration options in a board's mpconfigboard.h
file.

Damien George 01dd7804b8 ports: Make new ports/ sub-directory and move all ports there.
This is to keep the top-level directory clean, to make it clear what is
core and what is a port, and to allow the repository to grow with new ports
in a sustainable way.
