Python J-Link scripting

Dependencies

• Python 3
• https://pypi.org/project/pylink-square/ (Attention: When installing via pip take care that it is named "pylink-square")
• https://github.com/posborne/cmsis-svd => Currently do not use the version from pip, as it does not contain SVDParser.for_mcu but install from repo. Caution: On windows you have to copy the data directory to python\cmsis_svd directory as the symlink does not work correctly for installation
• https://github.com/eliben/pyelftools
• https://github.com/matplotlib/matplotlib
• JLinkARM.dll needs to be put into the root script directoy
• https://docs.pytest.org/

Target code dependencies

• https://github.com/bblanchon/ArduinoJson
• SeggerRTT https://wiki.segger.com/RTT (BufferSizeDown should be increased to something like 256, BufferSizeUp can be decreased to 256). If RTT needs to be used as print channel, use channel 1 for RPC.

Features

• STM32CUBEMX file parsing (*.ioc) for Pin config/names
• ELF-File parsing for finding symbol names/sizes
• Arbitrary register access by name
• All j-link functionalities (flashing, writing/reading memory, ...)
• GPIO sampling and plotting via JLink Memory Access
• rpc via RTT and json strings

Feature Backlog

• Ram code execution
• Automatic controller detection (Seems not to be possible)
• IOC parser: Analog signal sorting
• Replace RPC json by cbor or messagepack
