Hi Sandra, The documentation is in the ARMV8-M Security Extensions in: ARM®v8-M Security Extensions: Requirements on Development Tools document I linked in the email above and subsequent emails (http://infocenter.arm.com/help/topic/com.arm.doc.ecm0359818/index.html). Also per patch I refer to the relevant sections. So for instance in PATCH 3/7 refers to Section 5.4, which describes Entry functions and mentions the cmse_nonsecure_entry attribute. Whereas PATCH 7/7 refers to Section 5.4.3 of the same document which describes the cmse_nonsecure_caller intrinsic which that patch implements. Is there a specific intrinsic/attribute you are missing? Cheers, Andre
