A software download method and terminal

Abstract

Disclosed is a software downloading method, comprising: making a flash memory undetectable by a master control chip or making the master control chip detect a failure of the flash memory when software downloading of a terminal fails or downloaded software cannot work normally; restarting the terminal, and opening an emergency downloading port when the master control chip cannot detect the flash memory or detects a failure of the flash memory; enabling the master control chip to detect a state of the flash memory normally and identify the flash memory, and continuing downloading software by using the emergency downloading port. Also disclosed is a terminal. By means of the present invention, software downloading can be quickly repaired after the software downloading fails, thereby ensuring smooth software downloading, improving software downloading efficiency, and facilitating the operation.

Description

technical field [0001] The invention relates to software download technology, in particular to a software download method and a terminal. Background technique [0002] With the continuous promotion of the communication industry, mobile terminal products have been widely used. Moreover, due to the rapid development of communication technology, users have higher and higher requirements for product functions, which requires continuous upgrading of product software. When a bug is found in the software version, it is usually resolved through software upgrades. When the R&D personnel conduct version testing and verification, they generally use software upgrades to debug and verify the version. As the number of products increases, the frequency of software upgrades also increases accordingly. During the upgrade process, if there is a power outage, file corruption during normal use, or problems with the software version to be verified, the software upgrade on the terminal side will ...

AI Technical Summary

Problems solved by technology

In the end, the whole system can pass the inspection of the internal ROM, but in fact the software on the board side cannot work normally

In this case, the terminal-side software will go through the normal startup process, but actually it cannot work normally, so it cannot download and download the version under the normal process

In other words, when detecting the ROM code solidified in the chip, generally only verify whether there is code in NANDFLASH, or only verify whether the characteristic value of the code is legal, but cannot verify whether the entire code is complete or whether there are errors and logic problems in the code

When the download fails or there is a problem with the version itself, the data and codes in the NANDFLASH may be incomplete or have errors, but the characteristic values ​​of the codes are generally legal. In this way, when the ROM codes solidified in the chip are detected, It is likely to pass the test, and then run the incomplete code of NANDFLASH. In this way, the terminal-side software still cannot run normally, and it is impossible to continue downloading and downloading
