I have active MPU on secure side and run out of section for cover all specific areas.
What kind of default memory attributes has Boot-Rom area. MPU cover it with privileged access right.
But typical executable area have the next memory attributes:
What about normal FLASH memory area attributes ? Are they by default the same ?
MPU default settings can keep those areas with privileged access right what is OK for me.
But If I not specify others, may be some performance penalty or some other degradation can happens.
In can see in FreeRTOS port for LPC, some area is covered explicitly with those attributes as well.
Can those code area stay as it is or extra MPU atrributes bring some required settings and/or benefits ?
