Getting Started 

Setup 

The setup consists of RPi4 acting as a server for the inbound commands issued by the STM32H7555 board. The RPi4 can be used also for development & flashing the STM32H7555 board since it is running Ubuntu. The steps from this page can be executed on the RPi4 board. The steps marked with can be executed on the Raspberry from the test setup.

Hardware 

RPi4 (x1)
FTDI 232 (x1)
NUCLEO H755 (x1)
SPI SD Card Module (x1)
Mini USB cables (x1) - FTDI
Micro USB cable (x1) - Debug UART
Micro HDMI cable (x1) - Monitor
Keyboard & mouse

Warning

Please note that the FTDI chips should be configured with jumper on 3.3v

Dependencies 

cmake - Build system
openocd - Flashing & debug utilities
gcc-arm-none-eabi - Cross compiler
gdb-multiarch - Debug utility
minicom - Debug utility (serial console)

To install the dependencies use the following command

$ sudo apt-get -y install cmake openocd gcc-arm-none-eabi build-essential gdb-multiarch libnewlib-arm-none-eabi minicom

Usage 

Clone the repository

$ git clone https://github.com/endurosat/es-csp-client-freertos

Build

$ source configure
$ es_build

The resulting build artefacts are stored inside the build directory. After a succesfull build the contents of this directory should look like this:

. build
├── CMakeCache.txt
├── CMakeFiles
├── cmake_install.cmake

Open the Debug UART 

$ minicom -b 115200 -D /dev/ttyACM0

Start the ES CSP server 

In order to build and start the es csp server for these instructions

Flash the target (STM32H755 Nucleo Board)

Use the following command to flash the target.

$ source configure
$ es_flash_target

At this point the green LED on the development board should be toggling each 1000ms. The yellow LED is toggled on each byte received over the UART. The red LED is set if the application enters an error hook.

On the debug UART similar output to the one below should be displayed:

2 main [INFO] (47): ES Client v100
5 es_sd_card [INFO] (576): SD Card Mounted Successfully
5 es_sd_card [INFO] (580): TotalSpace : 7794688 bytes, FreeSpace = 7791264 bytes
5 es_client [TRACE] (54): Initializing ES Client
5 es_tasks [INFO] (108): Starting: Default task
5 es_tasks [INFO] (108): Starting: ES Client task
