It is also to be understood that the terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used in the specification of the present invention and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
It should be further understood that the term "and/or" as used in this specification and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.
The English explanation that the invention needs to relate to is as follows:
host: a host;
vendor Command: vendor specific protocol commands;
NandFlash: a kind of memorizer;
NorFlash: a non-volatile flash memory;
bootrom: a chip power-on starting program;
bootloader: a boot program;
FW: firmware;
ROM: a read only memory.
As shown in fig. 1, the TF card chip start includes a bootrom phase, a Bootloader phase and an FW firmware running phase; in an initial state, a ROM of the chip stores bootrom codes, a NorFlash stores Bootloader and FW codes, after the chip is powered on and started, the bootrom in the ROM operates, and the Bootloader codes are loaded into an operating space; then, the Bootloader code runs, and the code of the FW is loaded to the running space again; and finally, running the FW code and finishing the starting of the chip. In the online upgrading method, a Host device needs to design a time sequence for sending a Vendor Command, and after the Command is correctly sent, new firmware can be written into a TF card by using a common CMD25 (multi-block write) Command; however, if the Host Command timing designed by the Host cannot meet the requirement, the state in the card is likely to be abnormal after the Host Command timing is sent to the TF card, so that subsequent common read-write commands are likely to have problems, and the online upgrading process is likely to fail.
Referring to the embodiments shown in fig. 2 to 5, wherein, referring to fig. 2 to 3, the invention discloses a method for upgrading a TF card firmware, comprising the following steps:
s1, acquiring a command sequence issued by the host;
in this embodiment, before the step S1, the method further includes: and initializing an SD interface of the TF card so as to receive a command sequence issued by a host.
S2, judging whether the command sequence is the same as the preset value; if not, returning to execute the step S1;
the command sequence is a combination of a plurality of read commands, and the preset value comprises the sequence of the plurality of read commands and parameters thereof.
In this embodiment, the number of the read commands is 5, and the sequence and the parameters thereof are CMD17+0xa0000001, CMD17+0xa0000003, CMD17+0xa0000005, CMD17+0xa0000007, and CMD17+0xa0000002, respectively; the TF card receives the 5 read commands in sequence, and only when the sequence of the 5 commands and the parameters thereof completely accord with the preset conditions, the TF card can switch the internal read-write function of the NandFlash into the read-write function of the NorFlash.
S3, if yes, switching the read-write function of the TF card to NandFlash to the read-write function of NorFlash;
and S4, acquiring the new firmware issued by the host, and writing the new firmware into NorFlash to complete firmware upgrade.
In step S4, the area where the new firmware is written into NorFlash is the area where the old firmware in NorFlash is located, and the new firmware overwrites the old firmware.
In this embodiment, after the host cuts the new firmware into 4KB and aligns, the host writes the new firmware into the TF card by using an Open-ended CMD25 write command, at this time, the inside of the TF card writes the received new firmware data onto NorFLash, where the written location is a parameter of CMD25 (knowing a distribution location of firmware FW in NorFLash in advance, the location of the data to be written in NorFLash can be specified by using the parameter), and after the old firmware is overwritten, when the TF card system runs, Bootloader loads the updated new firmware.
Among them, the specific application scenario shown in fig. 3: and during online upgrading, directly covering the area of the old firmware in the NorFlash with the new firmware, and thus after the TF card is electrified again and operated, the Bootloader loads the new firmware.
In the invention, the Host only needs to send a common read command sequence (specifically a CMD17+ parameter, wherein the command sequence and the command parameter are in accordance with expectations), the read-write function of the NandFlash of the TF card is switched to the read-write function of the NorFlash, and then a common CMD25 (a plurality of write) command can be used for writing the new firmware into the TF card to complete the upgrade.
The invention upgrades the card by replacing the special protocol command defined by the original TF manufacturer with the common read-write command sequence (supported by Host equipment) of the TF card, thereby avoiding the strict time sequence requirement of the Host on the protocol command of the TF manufacturer, expanding the compatibility of the upgrading function of the TF card, enabling the TF card to be compatible with more Host equipment and improving the universality.
