PemicroProbe

✓ from pyocd_pemicro import PemicroProbe

✗ from pyocd.probe.pemicro import PemicroProbe

Minimal example to discover and connect to a PEMicro probe via PyOCD.

import os from pyocd.core.helpers import ConnectHelper # Ensure PEMicro library is available (install pypemicro) # List available probes probes = ConnectHelper.get_all_connected_probes(blocking=False) for probe in probes: print(probe.product_name) # Connect to the first available PEMicro probe if probes: session = ConnectHelper.session_with_chip(probe=probes[0], target='target_name') session.open() # ... debugging commands ... session.close()

Known issues

breakingpyocd-pemicro v1.0.4 added a dependency on pyocd, but v1.0.5 removed it to avoid circular dependency. If you upgrade from <1.0.5 to >=1.0.5, you may need to install pyocd separately.

fix

Install pyocd explicitly if needed: pip install pyocd

affects: from 1.0.4 to 1.0.5

deprecatedpypemicro v0.1.8 introduced an AttributeError in __del__(), causing v1.1.2 to revert to v0.1.7. Use pypemicro >=0.1.9 or >=0.1.10 with pyocd-pemicro >=1.1.3.

fix

Upgrade pyocd-pemicro to >=1.1.3, which requires pypemicro >=0.1.9

affects: pyocd-pemicro <1.1.3 with pypemicro 0.1.8

gotchaPEMicro library is not available on all architectures (e.g., Apple M1). pyocd-pemicro catches missing library exceptions and returns no probes silently.

fix

Check that your system architecture is supported by the PEMicro backend. On M1, use Rosetta or a x86_64 Python environment.

affects: all versions

gotchapyocd-pemicro is a plugin and must be installed in the same environment as pyocd. If installed separately, pyocd may not detect it automatically.

fix

Install both in the same environment; verify with: python -c "import pyocd.probe.pemicro"

affects: all versions
