python_lauterbach

A python implementation to control Lauterbach Trace32 software.

Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes. See deployment for notes on how to deploy the project on a live system.

Prerequisites

What things you need to install the software and how to install them

lauterbach-trace32-rcl 

Add below two line in your T32 config file(C:\T32\config.t32 normally)

RCL=NETTCP
PORT=20000

Installing

pip install lauterbach-trace32-rcl 

What this tool can do

This tool will open a trace32 software, and provide below functionlity:

1. Download elf/hex file;
2. Run cmm script;
3. Read/Write global variable;

Why this tool

This tool is part of EcuAutoTest, EcuAutoTest is used to control ECU software for testing, to do some ECU auto test.

A demo:

from python_lauterbach import python_lauterbach

with PythonLauterbach("C:/Lauterbach/T32_2022-02", "D:/test/debug.elf", "D:/test/setup.cmm") as debugger:
    # To read out a char TestArray[32] value;
    value = debugger.read_string_array_variable_value("TestArray", 32)
    # To read out a char *TestPointerArray[32] value;
    value = debugger.read_string_pointer_variable_value("TestPointerArray", 32)
    # To write a global arrary variable char TestArray[32] with data "AABBCC"
    debugger.write_string_array_variable_value("TestArray", "AABBCC")
    # To raed a none variable value, TestArray[1]
    value = debugger.read_variable_value("TestArray[1]")
    # To write a none variable value, TestArray[1]
    debugger.write_variable_value("TestArray[1]", "A")
