AI Technical Summary
Technical Problem
The existing RPMB bonding method results in significant hardware cost losses, especially when the chip fails or the CPU needs to be replaced, requiring the replacement of the bonded hardware.
Method used
During the target device reboot process, the value of the target flag bit is read from the Proinfo partition to determine whether it is the first preset value. If it is, the binding relationship between the RPMB partition and the eMMC storage is established to prevent the RPMB binding from being executed automatically after the device reboots.
Benefits of technology
It reduces the eMMC cost loss that may be caused by automatic RPMB binding after device restart, improves production efficiency and enhances data security.

Abstract
This disclosure provides a method, apparatus, device, and storage medium for RPMB partition binding. The method includes: responding to a preload message during a target device reboot process, reading the value of a target flag bit from a Proinfo partition, and determining whether the value of the target flag bit is a first preset value, wherein the first preset value is a target flag bit written to the Proinfo partition when the target device successfully boots up for the first time; if the target flag bit is determined to be the first preset value, then establishing a binding relationship between the RPMB partition and the eMMC memory, which specifically supports the eMMC memory to access the RPMB partition. Therefore, this embodiment of the disclosure uses the value of the target flag bit in the Proinfo partition to determine whether to execute the RPMB binding process, reducing the potential loss of eMMC memory due to automatic RPMB binding after a device reboot.
