Hi David,
the dyioib file paths are cryptic, but from the stack the I suspect the issue is with Segger J-Link.
Could you confirm you have installed J-Link. Have you used the Universal (I guess so) installer, or the Apple Silicon Installer?
No, SEC tool does not need Rosetta, but it might happen that if the PyOCD python finds library that is for different architecture and then it emits the messages that it has Intel architecture and it requires Arm.
If you have the Segger installed, I'd
- uninstall Segger
- try launching SEC tool
- install Segger again (preferrable the Apple Silicon Only version)
- try lanching SEC tool
Please let me know your findings.
Regards,
Libor
P.S. I tried SEC tool on almost clean 15.1.1 and then upgraded to 15.2 Sequoia (M1) - in both cases the SEC tool runs there.
