Attendees:

• Tamas Ban
• David Brown
• Andrzej Puzdrowski (nvlsianpu)
• Fabio Utzig
• Michel Jaouen
• Roman Okhrimenko
• David Vincze

Agenda:

• Agenda bashing
• Zephyr not moving to Mbed TLS 3.0 until after 2.7.
• Travis, and FIH tests
• 1.8 release

Topics:

• Travis, FIH test Tamas to get someone to resolve this
  • Fabio mcu-tools has a fork of TF-M to use
  • Start making it work again in Travis, then look to migrating to GH workflow
• Need to get a FIH build without testing
  • Andrzej to investigate
• Patch from Renesas re larger alignment
  • No simulator tests, so we don't know about when resets
  • Will not work with MCU manager (MCU manager will assume 8 bytes still)
  • Using updated magic for non 8-byte alignment
    • when 8, use existing magic
    • when other, use different 14-byte magic, and add 2 bytes at the end of magic to indicate the alignment used.
  • Work needs to be done on 'main', not on 1.7.
• v1.8
  • Need FIH fixes (ideally with Travis/GH tests) and build tests
  • Whether alignment is done depends on timing.

Actions:

• Fabio to investigate simulator tests for larger alignment patch and inform David if unable
• David to add an FIH build to GH Workflow CI
• Tamas to have someone get Travis FIH testing working
• David or Fabio to convert Travis FIH test to GH workflow
