Flashing AIR001 fails with “Memory transfer fault” on pyOCD > 0.36.0 but works on 0.36.0
Describe the bug When using pyOCD versions higher than 0.36.0, flashing AIR001 fails with a memory transfer error. The same command works correctly on pyOCD 0.36.0.
Command:
pyocd flash --erase chip --target air001 fw.hex
Error message:
C Memory transfer fault (write) @ 0x20001000-0x2000107f [__main__]
Using pyocd 0.36.0, the flashing completes successfully without any issues.
To reproduce
-
Install pyOCD >= 0.37.0
-
Run the command:
pyocd flash --erase chip --target air001 fw.hex -
Observe the memory transfer fault error.
Expected behavior The firmware should flash normally as it does in version 0.36.0.
Actual behavior Flashing fails with a “Memory transfer fault (write)” error.
Environment
- pyOCD version: 0.36.0 (works), >0.36.0 (fails)
- Target: AIR001
- OS: Windows 10 22H2 19045.5737
- Python version: 3.11.5
- ST-Link：V2J45M30
Additional context It looks like something changed after 0.36.0 that affects AIR001 memory writes (possibly RAM region config or flash algorithm behavior).
