Figure 53. MPU configuration for Quad-SPI region

SDRAM and Quad-SPI MPU configuration example

The following code (generated by STM32CubeMX) shows how to set the MPU attributes for

the FMC_SDRAM and Quad-SPI respecting the previously described configurations.

/* MPU Configuration */

void MPU_Config(void)

{

MPU_Region_InitTypeDef MPU_InitStruct;

/* Disables the MPU */

HAL_MPU_Disable();

/* Configure the MPU attributes for region 0 */

/* Configure the MPU attributes for SDRAM to normal memory*/

MPU_InitStruct.Enable = MPU_REGION_ENABLE;

MPU_InitStruct.Number = MPU_REGION_NUMBER0;

MPU_InitStruct.BaseAddress = 0xC0000000;

MPU_InitStruct.Size = MPU_REGION_SIZE_8MB;

MPU_InitStruct.SubRegionDisable = 0x0;

MPU_InitStruct.TypeExtField = MPU_TEX_LEVEL1;

MPU_InitStruct.AccessPermission = MPU_REGION_FULL_ACCESS;

MPU_InitStruct.DisableExec = MPU_INSTRUCTION_ACCESS_ENABLE;

MPU_InitStruct.IsShareable = MPU_ACCESS_NOT_SHAREABLE;

MPU_InitStruct.IsCacheable = MPU_ACCESS_CACHEABLE;

MPU_InitStruct.IsBufferable = MPU_ACCESS_BUFFERABLE;
