你好,
请问:1、是否每颗ARM SOC芯片都有一个ID识别码? 2、这个ID是硬件写死的吗?还是由底层软件定义设置的?若是由软件设置则ID就是可修改的,ID还有什么意义呢?
谢谢。

更正问题: 1、对所有ARM 内核IP或其SOC芯片,应都有一个“唯一的型号ID” , 想问:该“唯一的型号ID”是否一定要 以硬件方式写死在 “应用该IP的芯片中”不可修改? 并且都是可被读取查看的 ?2、ARM SOC的 “唯一的型号ID” ,是否也一样? 谢谢。 3 、每颗 ARM SOC 芯片若都有一个唯一 ID 识别码,只能是软件定义设置?不可能是硬件写死的? 谢谢。

我认为,通过OTP方式,每颗 ARM SOC 芯片都可有唯一硬件ID,不可修改,可读取;只是需SOC批量生产流程增加一个环节,成本高点。不知实际是否是这样做的? 请ARM专家指点下。谢谢。

一般都会有,每个SoC都有唯一的Key和秘钥(如果要支持TrustZone的话),一般是存在efuse上,
