DEF CON 29 - Laura Abbott, Rick Altherr -Breaking TrustZone M: Privilege Escalation on LPC55S69

[@gertvbiljon]

Thanks Laura and Rick! I learned more about the security on the LPC55s69 from this presentation than from reading the manual. Till now, I really liked the chip, particularly as it contains the Powerquad DSP processor which makes the work I do analyzing the Amps and Volts waveforms coming back from electric motors used in irrigation a breeze Starting to think that the open source Risc-V chips will be the future architechture I will use? Thanls plenty!

Thanks for the great presentation! Just a heads up there is an error on the slide at 7:08, it incorrectly lists EL0-4. There are 4 exception levels in Cortex-A 0-3, 0-4 would be 5 exception levels.

What is an "Application Note" she keeps mentioning at the start of the presentation?

I SPECULATE that the reason that the one section was removed from the users manual was that the chip implementation had a bug, and it was easier to just not support the feature at all, rather than to errata and fix it. This is usually a marketing decision about how many sales will be lost by not having the feature.
