What the developer wrote
Authored by Jean Do
adds maixpy_yahboom_devkit to krux script (#718)
which has been built since late 2024 with --unsupported flag,
and flashed like via maixpy_yahboom
What changed, and why it matters
This commit simply adds another supported hardware device name to a build/flash helper script. It does not change any cryptographic, wallet, or security-sensitive code. There is no indication of a vulnerability or security fix.
No security action required. Treat as routine device-support expansion.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The patch extends the ‘krux’ shell script to recognize ‘maixpy_yahboom_devkit’ as a valid device for both the ‘build’ and ‘flash/boot/erase’ commands. It adds two identical string comparisons to existing OR-chained device checks. The new device uses the same USB vendor/product ID mapping as other Yahboom-compatible boards. No logic, permissions, or trust boundaries are altered.
