address 0 can be a restricted memory region such as ROM code. I am making this PR to solve this PR#79993.Here as CONFIG_XIP=n, both .text and .data are placed in SRAM region and FLASH section get the default value 0 and size 0. Even it is not used FLASH_0 mpu region is creat...
The RAM region is not associated with the device tree at all. The RAM base address is always hardcoded to 0, which obviously causes problems if the RAM base address isn't at that location according to the device tree. The RAM region's size is fixed, also not associated with the device ...
简单概括一下,MPU 最多支持 8/16 个主空间划分(MPU_RNR[REGION],REGION取值 0-7 或者 0-15),每个主空间可以自由设置其属性(MPU_RASR[XN/AP/TEX/S/C/B]),空间大小是可设的,最小粒度为 32bytes,空间之间也可以重叠(高序号空间属性会覆盖低序号空间属性)。当某个主空间分配的大小超过 256 bytes 时,这...
