Embodiment Construction

[0043] A secure and flexible approach to firmware upgrades such as figure 1 shown, including the following steps:

[0044] Step 1: The user triggers to enter the upgrade, and the upgrade program is started at this time, and the name is p1;

[0045] Step 2: p1 downloads the firmware header according to the firmware address provided by the user;

[0046] Step 3: After the download of the firmware header is completed, p1 judges whether the firmware data provided by the user is correct. If the firmware data is wrong, go to step 4. If it is correct, go to step 5;

[0047] Firmware data is divided into different data partitions according to the partition of the device. Each partition has a partition header to mark the information of the partition. The information includes partition version, partition size, partition data type, partition encryption method, and partition compression method. , Partition check value; the partition data types include: bin file, ordinary file, nand data...

Abstract

The invention relates to a method for safely and flexibly upgrading a firmware. The method comprises the following steps of a used triggers to enter an upgrading process, starts an upgrading program named p1; the p1 downloads a firmness head according to a firmness address provided by a user, judges whether the firmness data provided by the user is correct or not, kills all processes but self if the firmness data is correct, and downloads the entire firmness to an internal memory; the p1 sets and stores the synchronous information through p1 after the entire firmness is downloaded, zones an upgrading subprogram, deciphers and uncompresses, and extracts the upgrading subprogram named as p2; the p1 calls p2 to complete the upgrading action, and waits for the completion of the upgrading; the p2 detects whether the firmness is legal or not, stops the upgrading if the firmness is illegal and notifies the p1, and carries out specific upgrading action on equipment if the firmness is legal; the p2 deciphers and uncompresses the zoned data, and then carries out the equipment upgrading; and the p1 is notifies after the p2 completes the decipher and uncompressing, and the equipment is restarted to complete the upgrading. Due to the adoption of the method, the upgrading security is improved, and the completeness of the firmness is guaranteed.

Description

technical field [0001] The invention belongs to the field of computer software, and in particular relates to a safe and flexible firmware upgrading method. Background technique [0002] Firmware is a type of software that provides internal control over electronic devices. Typical electronic devices with firmware include: end products for individual users, such as remote controls, calculators, mobile phones, digital cameras; computer-related components or devices, such as hard drives, keyboards, optical drives, monitors, memory cards; scientific instruments ; Industrial robots, etc. Firmware provides very basic, low-level operation for electronic devices; without firmware, electronic devices will not work at all. [0003] Firmware is usually stored in a non-volatile memory of an electronic device, such as ROM, PROM or Flash. The firmware needs to be upgraded, and the upgrade is usually for correcting errors of the original firmware, or adding new functions to the electroni...
