Maybe you should read? The secure enclave is completely separate to TrustZone on an iPhone and has nothing to do with Qualcomm.

The phone the FBI got into have a secure enclave though, IIRC.

You aren't talking about the San Bernardino iPhone 5c that had a A6 series CPU which predated the introduction of secure enclave are you?

We aren't in a thread about the FBI getting into a "shooter's" iPhone...aren't we?

E: ah, my original post is missing a negation. Too late to edit.

Is it not true that you did not intend to answer a rhetorical question with a rhetorical question as a negative confirmation, is it?

I assumed my prior posting was correct and that you had somehow missed critical context.

Edit: many in this thread appear to be missing critical context, as the secure enclave is not in play.

The iPhone 5C predated the introduction of the secure enclave. The 5C contains an A6 chip; according to page 7 of https://www.apple.com/business/docs/iOS_Security_Guide.pdf, the secure enclave is only available with A7-based devices or newer.

"Inside, the 5c packs the same Apple A6 processor featured in the iPhone 5, a Qualcomm MDM9615M LTE modem, and a Qualcomm WTR1605L LTE/HSPA+/CDMA2K/TDSCDMA/EDGE/GPS transceiver. The back of the logic board features assorted power management, flash, and controller components from Toshiba, Qualcomm, and Broadcom, as well as a Murata Wi-Fi module. "

Iphone 5c has qualcomm stuff in it.

:facepalm:

TrustZone is an ARM thing for the general-purpose computer on the device. The modem and radio are not relevant to discussions on TrustZone.

You're trying too hard.
