看到这里,你会发现i.MXRTyyyy的efuse里的LOCK控制是同时针对efuse本身和shadow register的;而i.MXRTxxx的OTP里的LOCK控制仅针对shadow register,那么对OTP本身的保护在哪里呢?先别急,后面会给你答案。 Shadow Lock控制在OTP的BANK0_word4、BANK1_word8/9,如下是RT600具体Lock bit定义: 关于OTP空间所有bit定义...
For example, when fusing the SRK_HASH, we use Bank 6 and Bank 7, while to close the device, we use Bank 1, Word 3:fuse prog 1 3 0x2000000 # Setting Bit 25 to enable SEC_CONFIGCould you please point me to the section in the reference manual where this is documented? Regards, Sri...
2.仅当secureboot使能时,必须选择首次烧写对应的安全镜像;当用于读取数据或者烧写OTP bank0时可不选择镜像 3.选择”eFuse密钥”文件选择按钮,选择配置好的otp_efuse_config.json 4.勾选”OTP”或者”烧录eFuse”选项 5.BKFIL工具选择主界面,点击”烧录”按钮 BKFIL读写OTP、eFuse步骤 三、常见问题分析...
