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. Contents ======== - Status - Serial Console - Configurations 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. 2022-04-03: The dependency on TrustedFirmware-M was dropped. I.e. the b-u585i-iot02a:nsh configuration now runs standalone. Clock Source ============ Only the low speed external (LSE) 32.768kHz crystal (X2) is installed in default configurations. FUNC GPIO --------- ---- OSC32_IN PC14 OSC32_OUT PC15 --------- ---- Arduino Connector ================= CN13 / SPI1 / D10 - D13 FUNC GPIO --------- ---- SPI1_NSS PE12 SPI1_SCK PE13 SPI1_MISO PE14 SPI1_MOSI PE15 --------- ---- Serial Consoles =============== Virtual COM Port on USART1 -------------------------- 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. Pins and Connectors: FUNC GPIO Connector Pin NAME ---- ---- ------ -------- TXD: PA9 CN9 14 T.VCP_TX RXD: PA10 CN9 13 T.VCP_RX ---- ---- ------ -------- 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_ARM_TOOLCHAIN_GNU_EABI=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.
