SREC-Loader

This repository contains code for a simple host-side loader, that uploads SREC-encoded executable to a UART-connected device running a SREC bootloader.

Usage

To upload, you need a SREC dump of your image.

Usage:

./uart_flasher <filename> <port identifier> [run command]

• filename is an absolute or relative path to the SREC dump
• port identifier is a name of, or a path to the serial port to be used (e.g., COM4, /dev/ttyUSB0, ...); please note, that MS Windows requires the COM port name in the form of \\.\COM12 for ports with identifier larger than 9
• run command - command to execute after loading is done
  • when not specified, the loader ends after the upload is done
  • local - runs only a local listener (in-program loop that reads characters from the port)
  • putty - attempts to find PuTTY installation and run it after the loading is done

Examples:

./uart_flasher kernel.srec COM4 putty
./uart_flasher kernel.srec /dev/ttyUSB0
