What is openocd-svd?
openocd-svd is a Python-based GUI utility to access peripheral registers of ARM MCUs via combination of OpenOCD and CMSIS-SVD.
Features
- several ways to open SVD:
- command line argument
- standart file dialog
- special dialog where any SVD from cmsis-svd can be chosen
- tree view for SVD registers and fields
- any value can be displayed in hex, dec or bin form (right click to choose)
- SVD clusters, cluster and register arrays supported (only flat view)
- SVD enums supported
- separate tabs for peripherals
- auto-polling openocd connection every 1s: get current MCU state and PC
- auto-read option to read registers when MCU halted and PC changed (manual read by default)
- auto-write option to write register immediately after it changed (manual write by default)
Dependencies
How to use
- Find and download SVD file with peripheral register structure of your MCU (can be found in Google, vendor site or cmsis-svd repo)
- Connect MCU with OpenOCD any way you like (GDB, raw scripts, etc)
- Start openocd-svd and open SVD file (or pass path to SVD as first argument at start)
- Press Connect to access OpenOCD via telnet interface (localhost 4444)
- Use View menu to access peripheral registers you want
Example run (SVD path argument is optional):
python3 openocd_svd.py %svd_file_path%
