Python RCL 调试劳德巴赫

比较旧的调试方式是TRACE32 Remote API, 看起来比较麻烦
新的是RCL
trace32的安装路径下有官方的python教程, 用浏览器可以打开
- <path>/demo/api/python/rcl/doc/html/index.html
需要先安装python库, 也在trace32安装路径下
- <path>/demo/api/python/rcl/doc/dist
- pip install lauterbach_trace32_rcl-latest-py3-none-any.whl
原理是python与Trace32客户端通过TCP通信, 所以需要先配置config.t32文件, 填入端口等等
bash 复制代码
```
<mandatory blank line>

RCL=NETASSIST
PORT=20000
PACKLEN=1024

RCL=NETTCP
PORT=20000

<mandatory blank line>
```

然后先打开trace32, 再在python中连接

python 复制代码

import lauterbach.trace32.rcl as t32
dbg = t32.connect(node='localhost', port=20000, protocol="TCP", timeout=10.0)
dbg.print("Hello World!")

点进rcl可以看到提供的接口, 这里用类封装了一些常用的, 比如调用cmm脚本, 打印, 暂停, 继续, 设置系统变量等; 还有设置地址,变量,控制内存,断点等等功能

python 复制代码

import lauterbach.trace32.rcl as t32
import datetime
import time

def time_now():
  return datetime.datetime.now().strftime("[%Y-%m-%d %H:%M:%S]")

class classLauterbach():
  def __init__(self) -> None:
    self.dbg = t32.connect(node="localhost", port=20000, protocol="TCP", timeout=10.0)

  def print(self, msg):
    self.dbg.print(msg)

  def my_script(self):
    self.dbg.cmm(cmd="./my_script.cmm", timeout=15.0)
    
  def pause(self):
    self.dbg.break_()
    self.dbg.print(f"{time_now()} mcu pause")

  def go(self):
    self.dbg.go()
    self.dbg.print(f"{time_now()} mcu go")

  def system_down(self):
    self.dbg.cmd("SYStem.Mode Down")
    self.dbg.print(f"{time_now()} mcu system down")

  def system_up(self):
    self.dbg.cmd("SYStem.Mode Up")
    self.dbg.print(f"{time_now()} mcu system up")

if __name__ == '__main__':
  Lauterbach = classLauterbach()
  Lauterbach.system_up()
  print(f"{time_now()} system up")
  time.sleep(30)
  Lauterbach.pause()
  time.sleep(30)
  Lauterbach.go()
  time.sleep(30)
