pyOCD is an Open Source python library in order to program and debug ARM Cortex-M microcontrollers using CMSIS-DAP. You can either use a python interpreter to control your target or start a GDB server.
From a python interpretor:
From a GDB client, you have all the features provided by gdb:
$ cd /path-to-pywinusb/ $ python setup.py install
$ sudo apt-get install python libusb-1.0-0-dev $ cd /path-to-pyusb/ $ sudo python setup.py install
from pyOCD.board import MbedBoard import logging logging.basicConfig(level=logging.INFO) board = MbedBoard.chooseBoard() target = board.target flash = board.flash target.resume() target.halt() print "pc: 0x%X" % target.readCoreRegister("pc") pc: 0xA64 target.step() print "pc: 0x%X" % target.readCoreRegister("pc") pc: 0xA30 target.step() print "pc: 0x%X" % target.readCoreRegister("pc") pc: 0xA32 flash.flashBinary("binaries/l1_lpc1768.bin") print "pc: 0x%X" % target.readCoreRegister("pc") pc: 0x10000000 target.reset() target.halt() print "pc: 0x%X" % target.readCoreRegister("pc") pc: 0xAAC board.uninit()
##GDB server example: Python:
from pyOCD.gdbserver import GDBServer from pyOCD.board import MbedBoard
import logging logging.basicConfig(level=logging.INFO)
board = MbedBoard.chooseBoard() # start gdbserver gdb = GDBServer(board, 3333)
gdb server:
arm-none-eabi-gdb basic.elf <gdb> target remote localhost:3333 <gdb> load <gdb> continue
An interface does the link between the target and the computer. This package contains basic functions to write and read data to and from an interface. You can inherit from Interface and overwrite read(), write(),... Then declare your interface in INTERFACE (in pyOCD.interface.init.py)
A target defines basic functionalities such as step, resume, halt, readMemory,... You can inherit from Target to implement your own functions. Then declare your target in TARGET (in pyOCD.target.init.py)
Defines the transport used to communicate. In particular, you can find CMSIS-DAP. Defines functions such as memWriteAP, memReadAP, writeDP, readDP,... You can inherit from Transport and implement your own functions. Then declare your transport in TRANSPORT (in pyOCD.transport.init.py)
Contains flash algorithm in order to flash a new binary into the target.
Start a GDB server. The server listens on a specific port. You can then connect a GDB client to it and debug/program the target
Then you can debug a board which is composed by an interface, a target, a transport and a flash
