> As far as I understand, the sharable attribute is only suitable for SMP system, which indicate that the memory will be accessed by multiple CPU concurrently and cache system must do the sync in hardware level. Since ARM never officially support SMP for armvx-m architecture, MPU_RASR_S doesn't make sense for cortex-m at all. What about DMA? Doesn't shareable allow multiple DMA requests to the same memory block? -- This is an automated message from the Apache Git Service.
