SoC data recovery system and method

Abstract

The invention discloses an SoC data recovery system and method. The system comprises a host, an SoC chip, a card reader, a path selection switch and a memory card; a first data path is formed between a data read-write interface of the host and the SoC chip, a second data path is formed between the data read-write interface of the host and the card reader, and the memory card is used for storing data files generated when the SoC chip runs; the host is used for controlling the access selection switch to access the memory card to the SoC chip through the data read-write interface in an initial state and reading and writing data from the first data access, controlling the access selection switch to access the memory card to the card reader through the data read-write interface when receiving a data recovery instruction and replacing the damaged data file in the memory card with the backup file through the second data path, and after the replacement is completed, controlling the path selection switch through the data read-write interface to access the memory card to the SoC chip so as to enable the SoC chip to normally run again. According to the invention, remote online SoC data recovery can be realized.

Description

technical field [0001] The invention relates to the technical field of SoC chip control, in particular to a SoC data recovery system and method. Background technique [0002] SoC is a system-level chip, also known as a system on a chip, which contains a complete hardware system (which can write system-level code and run an operating system) and carries all the content of embedded software, and more integrated processors (including CPU, GPU, DSP), memory, baseband, various interface control modules, various interconnection buses, etc. However, in the process of remote operation and application of the SoC chip, it is often encountered that the operating system or embedded software data is damaged or lost due to improper operation or accidents such as power failure and network disconnection, resulting in SoC chip failure to operate normally, and A problem that cannot be recovered after restarting. [0003] When this kind of problem occurs, the current common solution is usual...

AI Technical Summary

Problems solved by technology

However, this solution has major defects. If the location of the SoC chip is too far away, the solution will take too long, the operation and maintenance cost will be too high, and the technical level of the operation and maintenance personnel is required to be high. Failure to troubleshoot or the possibility of the same problem recurring after troubleshooting
