FirmwareHandler

A simple class for converting a firmware file (IntelHEX) into a sequence of commands and sending it to the bootloader on the STM32.

Using

• Add a library for working with half-serial ports to your project - jSerialComm;
• Copy a class to work with firmware;
• Open a file stream and calculate the start and end addresses:

FileInputStream fis = new FileInputStream(file);
int[] addresses = FirmwareHandler.getFirstAndLastAddresses(fis);
fis.close();

• Reopen the stream and call the main method for sending the firmware. The function returns the number of bytes sent by STM32:

fis = new FileInputStream(file);
int bytes = FirmwareHandler.transmitFirmware(selected_port, fis, addresses);

Launch

java -cp SerialPortTest.jar org.example.Main

or with the port number and path to the firmware file:

java -cp SerialPortTest.jar org.example.Main 2 ../../SimpleAppWithBootloader.hex

Links

• Bootloader - the bootloader that the current program is running with.
