FirmwareUpdate Application Description

The FirmwareUpdate application saves the new firwmare received via NFC using the ST FTM protocol and saves it on the right flash region and works with the SimpleBootLoader example for enabling the Firmware Update capability.

The package supports battery operated use cases.

This firmware package includes Components Device Drivers, Board Support Package and example application for the following STMicroelectronics elements:

• STEVAL-SMARTAG2 (SmarTag2) evaluation board that contains the following components:
  • MEMS sensor devices (LPS22DF, STTS22H, LIS2DUX12, H3LIS331DL, LSM6DSO32X)
  • ambient light sensors(VD6283TX)
  • dynamic NFC tag (ST25DV64KC)

The example application allows the user to control the initialization phase via UART.

Launch a terminal application and set the UART port to 9600 bps, 8 bit, No Parity, 1 stop bit. For having the same UART functionality on STEVAL-SMARTAG1 board, is necessary to recompile the code uncomment the line

//#define SMARTAG_ENABLE_PRINTF

Very Important

1. The firmware updated is done using the ST25 Android/iOS application (Version 3.7.0 and above)

2. This example must run starting at address 0x08002000 in memory and works ONLY if the SimpleBootLoader is saved at the beginning of the FLASH (address 0x08000000)

3. For each IDE (IAR/µVision/STM32CubeIDE) there are some scripts .bat/.sh that makes the following operations:

   • Full Flash Erase
   • Load the SimpleBootLoader on the rigth flash region
   • Load the Program (after the compilation) on the rigth flash region
   • Dump back one single binary that contain SimpleBootLoader+Program that could be flashed at the flash beginning (address 0x08000000)
   • Reset the board

Keywords

NFC, SPI, I2C, UART

Hardware and Software environment

• This example runs on STEVAL-SMARTAG2 (SmarTag2) evaluation board can be easily tailored to any other supported device and development board.

• This example must be used with the ST25 Android (Version 3.7.0 or higher) /iOS (Version 3.7.0 or higher) application available on Play/itune store.

ADDITIONAL_COMP : ST25DV64KC

Dependencies

STM32Cube packages:

• STM32L4xx drivers from STM32CubeL4 v1.17.1

STEVAL-SMARTAG1:

• STEVAL-SMARTAG2 v1.1.0

How to use it?

This package contains projects for 3 IDEs viz. IAR, Keil µVision 5 and Integrated Development Environment for STM32. In order to make the program work, you must do the following:

• WARNING: before opening the project with any toolchain be sure your folder installation path is not too in-depth since the toolchain may report errors after building.

For IAR:

• Open IAR toolchain (this firmware has been successfully tested with Embedded Workbench V9.20.1).
• Open the IAR project file EWARM.eww
• Rebuild all files and load your image into target memory.
• Run the example.

For Keil µVision 5:

• Open Keil µVision 5 toolchain (this firmware has been successfully tested with MDK-ARM Professional Version: 5.37.0)
• Open the Keil µVision 5 project file MDK-ARM.uvprojx
• Rebuild all files and load your image into target memory.
• Run the example.

For Integrated Development Environment for STM32:

• Open STM32CubeIDE (this firmware has been successfully tested with Version 1.11.0).
• Set the default workspace proposed by the IDE (please be sure that there are not spaces in the workspace path).
• Press “File” -> “Import” -> “Existing Projects into Workspace”; press “Browse” in the “Select root directory” and choose the path where the CubeIDE project is located (it should be STM32CubeIDE).
• Rebuild all files
