你好,在UL1998的官方安全库的 status = STL_MARCH_TEST_testSafeRam((uint32_t *)0xC000,RAM_TYPE_PSA_CRC)函数中的RAM_TYPE_PSA_CRC的宏定义为0x001c(#define RAM_TYPE_PSA_CRC 0x001C),这个RAM_TYPE_PSA_CRC的值是什么意思,是代表地址为0X001C的内存还是PSA_CRC的ram内存区域,不是很理解这个宏定义干嘛用的,这个测试也是破坏性测试需要复制到RAM中,执行STL_MARCH_TEST_testSafeRam()汇编后被破坏,然后回复。地址范围怎么确定。
