Add support for STM32G474: Add B-G474E-DPOW1 board
Add support for the STM32G474 family of microcontrollers and the
B-G474E-DPOW1 Discovery Board, which features a STM32G474RET6.
This is a major pull request as it adds support for an entirely
new family of STM32. This support is implemented in
arch/arm/src/stm32 and shares implementation with other STM32
families supported by that code, such as the 'L15xx, 'F10xx,
'F20xx, 'F3xxx, and 'F4xxx.
boards/Kconfig:
* Make NuttX recognize the existence of b-g474e-dpow1,
the B-G474E-DPOW1 Discovery Board.

Status
|
||||
======
|
||||
|
||||
This port boots NuttX through to a functional NSH prompt.
|
||||
|
||||
|
||||
Development Environment
|
||||
=======================
|
||||
|
||||
Toolchains
|
||||
----------
|
||||
An appropriate ARM toolchain is needed, such as the one built with the
|
||||
customized NuttX buildroot or the ready-made GNU Tools for Arm Embedded
|
||||
Processors.
|
||||
|
||||
|
||||
Debugging
|
||||
---------
|
||||
The board incorporates a STLINK-V3E programmer/debugger accessible via the
|
||||
Micro-USB Type B connector.
|
||||
|
||||
To debug with OpenOCD and arm-nuttx-eabi-gdb:
|
||||
|
||||
* Use 'make menuconfig' to set CONFIG_DEBUG_SYMBOLS and CONFIG_DEBUG_NOOPT.
|
||||
To see debug output, e.g., the "ABCDE" printed in __start(), also set
|
||||
CONFIG_DEBUG_FEATURES.
|
||||
|
||||
* Build NuttX.
|
||||
|
||||
* Flash the code using:
|
||||
$ openocd -f interface/stlink.cfg -f target/stm32g4x.cfg -c init \
|
||||
-c "reset halt" -c "flash write_image erase nuttx.bin 0x08000000"
|
||||
|
||||
* Start GDB with:
|
||||
$ arm-nuttx-eabi-gdb -tui nuttx
|
||||
|
||||
* In GDB:
|
||||
(gdb) target remote localhost:3333
|
||||
(gdb) monitor reset halt
|
||||
(gdb) load
|
||||
|
||||
|
||||
Hardware
|
||||
========
|
||||
|
||||
MCU Clocking
|
||||
------------
|
||||
By default, the MCU on this board is clocked from the MCU's internal HSI
|
||||
clock, and only this option is supported by software at this time.
|
||||
|
||||
If software support is added for it, the MCU could be clocked from the
|
||||
following other sources: a 24 MHz oscillator on X2, MCO from STLINK-V3E, or
|
||||
external clock from connector CN9, pin 26.
|
||||
|
||||
|
||||
GPIOs
|
||||
-----
|
||||
|
||||
|
||||
Buttons
|
||||
-------
|
||||
The board has 5 user buttons in the form of a 4-direction "joystick" with a
|
||||
selection button (pressing down on the "joystick").
|
||||
|
||||
|
||||
LEDs
|
||||
----
|
||||
The board has 4 user LEDs.
|
||||
|
||||
|
||||
RGB Power LED
|
||||
-------------
|
||||
The board has a super bright RGB power LED.
|
||||
|
||||
Caution: For eye safety, ensure that the power LED is covered by the
|
||||
diffuser that comes installed over it.
|
||||
|
||||
|
||||
Serial Consoles
|
||||
===============
|
||||
|
||||
The MCU's USART3 is connected to the on-board STLINK-V3E and exposed to
|
||||
the PC as a Virtual COM Port over the same Micro-USB Type B connection used
|
||||
for programming/debugging.
|
||||
|
||||
On Debian Linux, this shows up as /dev/ttyACM0. Other operating systems may
|
||||
differ.
|
||||
|
||||
|
||||

/* The STM32G474RE has 512 KiB of FLASH beginning at address 0x0800:0000.
|
||||
*
|
||||
* When booting from FLASH, FLASH memory is aliased to address 0x0000:0000
|
||||
* where the code expects to begin execution by jumping to the entry point in
|
||||
* the 0x0800:0000 address range.
|
||||
*
|
||||
* The STM32G474RE has a total of 128 KiB of SRAM in three separate areas:
|
||||
*
|
||||
* 1) 80 KiB SRAM1 mapped at 0x2000:0000 thru 0x2001:3fff.
|
||||
* 2) 16 KiB SRAM2 mapped at 0x2001:4000 thru 0x2001:7fff.
|
||||
*
|
||||
* CCM SRAM (Routine Booster):
|
||||
*
|
||||
* 3) 32 KiB CCM SRAM mapped at 0x1000:0000 thru 0x1000:7fff
|
||||
* but also aliased at at 0x2001:8000 thru 0x2001:ffff to be contiguous
|
||||
* with the SRAM1 and SRAM2.
|
||||
*
|
||||
* Because SRAM1 and SRAM2 are contiguous, they are treated as one region
|
||||
* by this logic.
|
||||
*
|
||||
* CCM SRAM is also contiguous to SRAM1 and SRAM2, however it is excluded
|
||||
* from this linker script, to keep it reserved for special uses in code.
|
||||
* REVISIT: Is this the correct way to handle CCM SRAM?

||||
* Description:
|
||||
* Perform application specific initialization. This function is never
|
||||
* called directly from application code, but only indirectly via the
|
||||
* (non-standard) boardctl() interface using the command BOARDIOC_INIT.
|
||||
*
|
||||
* Input Parameters:
|
||||
* arg - The boardctl() argument is passed to the board_app_initialize()
|
||||
* implementation without modification. The argument has no
|
||||
* meaning to NuttX; the meaning of the argument is a contract
|
||||
* between the board-specific initialization logic and the
|
||||
* matching application logic. The value could be such things as a
|
||||
* mode enumeration value, a set of DIP switch settings, a pointer
|
||||
* to configuration data read from a file or serial FLASH, or
|
||||
* whatever you would like to do with it. Every implementation
|
||||
* should accept zero/NULL as a default configuration.
|
||||
*
|
||||
* Returned Value:
|
||||
* Zero (OK) is returned on success; a negated errno value is returned on
|
||||
* any failure to indicate the nature of the failure.
