Problems solved by technology
It can be seen that the above method requires the Host device to design a timing sequence for sending commands. If the designed timing cannot accurately meet the requirements, the internal state of the TF card will be abnormal after the Host sends it, which will directly affect the subsequent upgrade process and cause its upgrade. fail

The invention relates to a TF card firmware upgrading method and device, computer equipment and a storage medium, and the method comprises the steps: obtaining a command sequence issued by a host; judging whether the command sequence is the same as a preset value; if yes, a read-write function of the NandFlash in the TF card is switched into a read-write function of the NorFlash; and obtaining the new firmware issued by the host, and writing the new firmware into the NorFlash to complete firmware upgrading. According to the TF card upgrading method, the card is upgraded by replacing the original special protocol command defined by the TF manufacturer with the common read-write command sequence of the TF card, so that the harsh time sequence requirement of the host on the protocol command of the TF manufacturer is avoided, the compatibility of the TF card upgrading function is expanded, the TF card can be compatible with more host equipment, and the universality is improved.
Description
technical field [0001] The invention relates to the technical field of TF card firmware upgrade, in particular to a method, device, computer equipment and storage medium for TF card firmware upgrade. Background technique [0002] In the existing TF card firmware online upgrade method, the Host (host) device needs to send a Vendor Command (vendor special protocol command, such as: CMD56) customized by the TF card manufacturer during the upgrade process, and this command requires the Host device to design a Comply with the timing sequence of the manufacturer's special protocol command, and then send it to the TF card; after the TF card receives the command, it will change the original read and write function for NandFlash operation to the read and write function for NorFlash, when the Host reads and writes the TF card When operating, it is operating on NorFlash. Using this principle, the Host device writes the new firmware to the area of the old firmware in the NorFlash, dir...
