Hello, I'm trying to program an RPMB key on iMX6DLSABRESD. $mmc rpmb write-key /dev/mmcblk3rpmb rpmbkey RPMB operation failed, retcode 0x0001 I added
Host 接收到 RPMB 的数据、随机数以及签名后,首先比较随机数是否与自己发送的一致,如果一致,再用同样的 Secure Key 通过 HMAC SHA-256 算法对数据和随机数组合到一起进行签名,如果签名与 eMMC 发送的签名是一致的,那么就可以确定该数据是从 RPMB 中读取到的正确数据,而不是攻击者伪造的数据。 通过上述的读取流程...
mmc rpmb write-key <rpmb device> <key file> Program authentication key which is 32 bytes length and stored in the specified file. Also you can specify '-' instead of key file path to read the key from stdin. NOTE! This is a one-time programmable (unreversible) change. Example: ...
If U-Boot has been built withCONFIG_SUPPORT_EMMC_RPMBthemmc rpmbcommand is available for reading, writing and programming the key for the Replay Protection Memory Block (RPMB) partition in eMMC. When using U-Boot to write to eMMC (or microSD) it is often useful to use thegzwritecommand. ...

而对于MTD块设备,MTD设备层是不提供ioctl的实现方法的,也就不会有对应的MEMGETINFO命令之类,因此不能使用nandwrite,flash_eraseall,flash_erase等工具去对/dev/mtdblockN去进行操作,否则就会出现上面的现象一,同时也解释了现象3——用mtd2擦除分区后,在用mtdblock2进行umount就会造成混乱。
It is backward compatible with previous versions (v4.41/v4.5/v5.0), supporting features such as power-off notifications, packed commands, cache, boot or replay protected memory block (RPMB) partitions, high priority interrupt (HPI), and hardware (HW) reset. SpecificationsLatest Update: 2025-03-...
RPMB allows only authenticated access and prevents unauthorized data from being accessed in an RPMB partition. A unique authorized key is paired between the e-MMC device and the host. If e-MMC is paired with a different host (or vice versa), the RPMB partition will be inaccessible. ...
