Hi,Master:
MCU: STM32H743II
Question:
I configure the MPU for RAM as follows:
mpu_set_protection( 0x24000000,
MPU_REGION_SIZE_512KB,
MPU_REGION_NUMBER1,
MPU_REGION_FULL_ACCESS,
MPU_ACCESS_SHAREABLE,
MPU_ACCESS_NOT_CACHEABLE,
MPU_ACCESS_NOT_BUFFERABLE);
I found that an unaligned access fault is triggered at the location shown in Figure 1. The address shown in Figure 2 is within the MPU configuration range shown in Figure 3, but I do not understand why the fault is triggered.
Thank you very much!
