Can a HAB Encrypted Image Boot and Run from Internal Flash in i.MXRT10xx ?

[mjpovi]

Hi,
I wish to confirm my understanding of HAB Secure/Encrypted boot in that a HAB Encrypted image cannot be flashed or be booted and run XIP from the internal flash on an IMXRT10xx MCU.  HAB encrypted flashing/boot XIP is only supported using external flash (or executing from OCRAM) ?

Hi @mjpovi ,

Thanks for your interest in NXP MIMXRT series!

No. In fact, for the RT series, there is little difference between the so-called internal Flash and external Flash, both of which are connected using the FlexSPI. And HAB encrypted boot, does not support XIP.

Best regards,
Gavin
