Abstract
The invention relates to a wireless communication terminal and a software upgrading method thereof. The software upgrading method comprises the following steps of detecting whether a memory card which is connected to a PC (Personal Computer) has a version file to be upgraded by the wireless communication terminal; copying the version file from the memory card to an appointed position of a non volatile memory if yes; and then carrying out version upgrading on the version file to be upgraded. Compared with the prior art, the invention can directly realize repair upgrading on the PC without making use of an external tool. Through the invention, the convenience of upgrading can be enhanced, and the safety of upgrading can also be enhanced because the wireless communication terminal has a repair mechanism after the upgrading fails.
Description
Technical field
The present invention relates to communication technical field, particularly relate to a kind of wireless communication terminal and method for upgrading software thereof.
Background technology
Along with the continuous popularization of 3G, mobile broadband terminal product based on data card is widely used, and due to the develop rapidly of the communication technology, the requirement of user to the function of product is more and more higher, this constantly upgrades to the software of product with regard to requiring, along with increasing of product, the raising of upgrading frequency, to the requirement of upgrading also in continuous raising.The stability of upgrading, and the repair ability unsuccessfully of upgrading is all the problem that user pays close attention to.
Be illustrated in figure 1 the space of existing mobile terminal nonvolatile memory, comprise bootloader, terminal versions software and encrypted file system (Encrypting File System, EFS).
Be illustrated in figure 2 traditional software upgrading process flow diagram, it comprises following process:
201: after data card powers on start, complete the initial work of hardware, at this moment can see corresponding port information in the equipment manager of computer;
202: after the download tool of PC side is checked through port information, namely can send the instruction of download;
203: plate side joint is switched to downloading mode, and receives download plug-in after receiving instruction, run download plug-in (download plug-in is the mini system performing download function, different from the system that software normally runs);
204: the action carrying out edition upgrading;
205: if upgraded successfully, then enter normal operation mode after restart, complete edition upgrading;
206: if occur unsuccessfully in the process of upgrading, utilize JTAG instrument to repair, need emulator to assist;
207: upgrade successfully, then enter normal operation mode after restart, complete edition upgrading.
As mentioned above, current main software upgrade technique adopts the download tool of PC side to upgrade, upgrade unsuccessfully, directly cannot be repaired by PC side, JTAG mode can only be used or utilize USB to turn the chip of JTAG, the software reparation of complete paired terminal, but after above-mentioned two kinds of methods all need to remove the structure of terminal, just can carry out.Owing to using JTAG mode, need to use special instrument, this instrument is only in research and development debugging, or minority after-sales service can provide, and the price comparison of emulator is expensive.And use USB to turn the mode of JTAG also mainly in order to provide after sale service to use, and needing to be equipped with special USB turns the chip of JTAG, for customer upgrade failure, and reparation little.
