B-U585I-IOT02A README
|
||||
======================
|
||||
|
||||
This README file discusses the port of NuttX to the STMicroelectronics
|
||||
B-U585I-IOT02A board. That board features the STM32U585AII6QU MCU with 2MiB
|
||||
of Flash and 768KiB of SRAM.
|
||||
|
||||
This port is a proof-of-concept to demonstrate running NuttX in the Non-
|
||||
Secure TrustZone domain as a companion to TrustedFirmware-M (TFM). Running
|
||||
NuttX on the B-U585I-IOT02A without TFM is currently not supported.

Status
|

======
|
||||
2022-02-13: With TrustedFirmware-M from STM32CubeU5 and signing the Apache
|
||||
NuttX binary image to get a tfm_ns_init.bin, the board now boots and the
|
||||
basic NSH configuration works with Apache NuttX as the OS running in the
|
||||
non-secure world.
|
||||
|
||||
Clock Source
|
||||
============
|
||||
|
||||
Only the low speed external (LSE) 32.768kHz crystal (X2) is installed in
|
||||
default configurations.

Default board is configured to use USART1 as console. USART1 is connected
|

to the ST-LINKV3E Virtual COM port as well as made available on connector
|

CN9.

Configurations
|

==============
|
||||
|
||||
Information Common to All Configurations
|
||||
----------------------------------------
|
||||
Each configuration is maintained in a sub-directory and can be
|
||||
selected as follow:
|
||||
|
||||
tools/configure.sh b-u585i-iot02a:<subdir>
|
||||
|
||||
Before building, make sure the PATH environment variable includes the
|
||||
correct path to the directory than holds your toolchain binaries.
|
||||
|
||||
And then build NuttX by simply typing the following. At the conclusion of
|
||||
the make, the nuttx binary will reside in an ELF file called, simply, nuttx.
|
||||
|
||||
make oldconfig
|
||||
make
|
||||
|
||||
The <subdir> that is provided above as an argument to the tools/configure.sh
|
||||
must be is one of the following.
|
||||
|
||||
NOTES:
|
||||
|
||||
1. These configurations use the mconf-based configuration tool. To
|
||||
change any of these configurations using that tool, you should:
|
||||
|
||||
a. Build and install the kconfig-mconf tool. See nuttx/README.txt
|
||||
see additional README.txt files in the NuttX tools repository.
|
||||
|
||||
b. Execute 'make menuconfig' in nuttx/ in order to start the
|
||||
reconfiguration process.
|
||||
|
||||
2. Unless stated otherwise, all configurations generate console
|
||||
output on USART3, as described above under "Serial Console". The
|
||||
elevant configuration settings are listed below:
|
||||
|
||||
CONFIG_STM32L5_USART3=y
|
||||
CONFIG_STM32L5_USART3_SERIALDRIVER=y
|
||||
CONFIG_STM32L5_USART=y
|
||||
|
||||
CONFIG_USART3_SERIALDRIVER=y
|
||||
CONFIG_USART3_SERIAL_CONSOLE=y
|
||||
|
||||
CONFIG_USART3_RXBUFSIZE=256
|
||||
CONFIG_USART3_TXBUFSIZE=256
|
||||
CONFIG_USART3_BAUD=115200
|
||||
CONFIG_USART3_BITS=8
|
||||
CONFIG_USART3_PARITY=0
|
||||
CONFIG_USART3_2STOP=0
|
||||
|
||||
3. All of these configurations are set up to build under Linux using the
|
||||
"GNU Tools for ARM Embedded Processors" that is maintained by ARM
|
||||
(unless stated otherwise in the description of the configuration).
|
||||
|
||||
https://developer.arm.com/open-source/gnu-toolchain/gnu-rm
|
||||
|
||||
That toolchain selection can easily be reconfigured using
|
||||
'make menuconfig'. Here are the relevant current settings:
|
||||
|
||||
Build Setup:
|
||||
CONFIG_HOST_LINUX=y : Linux environment
|
||||
|
||||
System Type -> Toolchain:
|
||||
CONFIG_ARMV8M_TOOLCHAIN_GNU_EABIL=y : GNU ARM EABI toolchain
|
||||
|
||||
Configuration sub-directories
|
||||
-----------------------------
|
||||
|
||||
nsh:
|
||||
|
||||
Configures the NuttShell (nsh) located at examples/nsh. This
|
||||
configuration is focused on low level, command-line driver testing.

|

* 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 cold be such things as a
|
||||
* mode enumeration value, a set of DIP switch 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.

*
|

* 1. Provide logic in stm32_boardinitialize() to configure SPI chip select

* 2. Provide stm32_spi1/2/3select() and stm32_spi1/2/3status() functions

|

* selection and status operations using GPIOs in the way your board is

* 3. Add a calls to stm32_spibus_initialize() in your low level

* application initialization logic
|

* 4. The handle returned by stm32_spibus_initialize() may then be used
|
