In prior art, generally adopt the download tool of PC (PC) side to upgrade to terminal, upgrade unsuccessfully, directly cannot be repaired by PC side, although the software reparation of the complete paired terminal of JTAG mode can be passed through, JTAG mode needs to use special instrument, this instrument is expensive, only in research and development debugging, or minority after-sales service point can provide, therefore, for the situation of customer upgrade failure, reparation little.Further, in version downloading process, due to maloperation or version existing problems itself, cause failed download, and cannot continue to download, now, can only carry out wiping and again downloading with instruments such as TRACE, download efficiency is low and can cause the wasting of resources.
In addition, the main control chip of some terminal platform is integrated with NAND FLASH controller at present, main control chip can run one section of solidification ROM code in the chips when starting, to detect and to load the code in NANDFLASH, if pinpointed the problems in the process, code in ROM can enter urgent downloading mode, provides a urgent port that can supply to download.Fig. 1 is the schematic flow sheet after an existing terminal normal boot-strap, and as shown in Figure 1, this flow process comprises:
After starting up, main control chip jumps to inner ROM and performs.Whether inner ROM carries out corresponding initialization, and after completing initialization, main control chip carries out the detection to NANDFLASH by NAND FLASH controller, comprise and exist with effectively whether detection and BOOTLOADER thereof exist and effectively detect to NANDFLASH;
When detection by after, main control chip loads BOOTLOADER code in NANDFLASH to internal memory, and operation is loaded into the BOOTLOADER code of internal memory, and BOOTLOADER finally with the operating system on slide glass, and can give control the operating system on sheet.Now, whole terminal just completes start-up course, and last operation system starts upper layer application, provides corresponding function.
After detecting unsuccessfully (as: incorrect without BOOTLOADER or BOOTLOADER form in without NANDFLASH, NANDFLASH), main control chip processes under jumping to emergency mode, now, if be connected to PC, urgent download port will be there is, by using specific PC side software, can continue to download code.
Can find out, when NANDFLASH exist and its BOOTLOADER form is correct, at this moment, NANDFLASH and BOOTLOADER is by the detection by inner ROM, if but BOOTLOADER to be form (eigenwert of code) correct, and content incorrect, in other words, BOOTLOADER is normal, and in NANDFLASH, the version of operating system is incomplete or incorrect.Finally, whole system is by the detection of the ROM of inside, but the software cisco unity malfunction of actual upper plate side.In this case, end side software will carry out normal Booting sequence, but in fact cannot normally work, and also just cannot carry out downloading and download version under normal flow process.In other words, during solidification ROM code detection in the chips, in general only checking NANDFLASH, whether have code, or whether the eigenwert of only Validation Code is legal, can not verifies in the whether complete or code of whole code whether there is mistake and logical problem.And when failed download or version existing problems itself, be present in data in NANDFLASH and code may not be complete, also may be wrong, but the eigenwert of code is generally legal, like this, when solidification ROM code in the chips detects, possibly by detecting, then run NANDFLASH and incomplete code, like this, end side software still cannot normally run, and also just cannot continue to download and download.
