After learning into “Arm® Architecture Reference Manual”, I found that it’s my fault. Section K1.2.13 said “A memory access from a load or store instruction that crosses a page boundary to a memory location that has a different memory type or Shareability attribute r...
mode to some other mode while SCR.NS is 1. — Use an MCR instruction that writes SCR.NS to change from Secure to Non-secure state. This means ARM recommends that software does not alter SCR.NS in any mode except Monitor mode. ARM deprecates changing SCR.NS in any other mode. • ...
Is there a chance that NXP didn't add support for unaligned memory access, as it is described in ARM's Cortex-M7 technical reference manual? 0 Kudos Reply 02-28-2023 06:45 AM 1,943 Views gobbo Contributor II You don't happen to be accessing OCRAM2 with this ...
