Embodiment
Core of the present invention is for providing a kind of high-efficiency embedded type system debug method, and this high-efficiency embedded type system debug method can be avoided occurring again tearing flash open, burning flash, and the situation of welding flash occurs.
In order to make those skilled in the art understand better technical scheme of the present invention, the present invention is described in further detail below in conjunction with the drawings and specific embodiments.
Please refer to Fig. 1 and Fig. 2, wherein, Fig. 1 is the process flow diagram of high-efficiency embedded type system debug method in an embodiment of the present invention; Fig. 2 is the FB(flow block) of high-efficiency embedded type system debug method among the another kind of embodiment of the present invention.
The invention provides a kind of high-efficiency embedded type system debug method, comprise step:
S1, at first write the starter program, described starter program can be carried out initialization to system hardware;
S2, employing kermit, xmodem or zmodem exploitation serial port protocol;
S3, by in the starter program system hardware being carried out initialization, if initialization success then carry out S4; If initialization is unsuccessful, then initialization procedure can be with reference to the implementation of open source software code uboot;
S4, detect.
Particularly, in the starter program, increase the function by serial ports upgrading bootloader, and define function keys, the function key of before system hardware powers on, setting out, when moving, the starter program can whether be triggered by the automatic detection function key: if function key triggers, then load bootloader; If function key does not trigger, acquiescence continues to carry out from flash.
Particularly, bootloader is unsuccessful when loading, and then need again debug bootloader, is carrying out above same steps as; When loading the bootloader success, then by order bootloader is burnt to flash.
Particularly, when the starter program is moved, do not trigger if do not detect function key, if also do not have burning good bootloader among the flash this moment, then starter can give tacit consent to the interface of bootloader to be loaded such as resting on; If had burning good bootloader among the flash this moment, then directly start bootloader from flash.
The objective of the invention is to avoid often dismantling flash and can efficient and the reducing development cost of direct burning flash to improve debugging embedded system.Mainly be before the bootloader operation, carry out the starter program that we write ourselves, this program is mainly to the device (cpu of system's necessity, ddr, serial etc.) carry out initialization, and must support serial port protocol, such as kermit/xmodem/zmodem etc., and provide the function of serial ports upgrading Bootloader.After only needing the good starter of a burning, just can load debugging to bootloader by starter.Even the bootloader failure also only need to be reloaded Bootloader and be got final product, record starter does not need to reburn.
The technical matters that the present invention solves and the scheme of employing are: when general debugging new product, at first to debug bootloader, and in debug process, need multiple reversal to review the card debugging, this just inevitably goes repeatedly to dismantle flash and burning, so not only lose time, and can often integrated circuit board occur or flash is damaged.When debugging with simulator, must must bear its fancy price and impaired possibility.Propose my scheme: at first write an initialize routine starter.bin who simplifies most, only the device to cpu/ddr/serial/clock necessity carries out initialization in this program for this reason, and supports the function of serial port protocol and loading bootloader.When the debugging new product, need only starter.bin of burning, follow-uply just can debug bootloader by the function of the loading bootloader among the starter, when avoiding directly debugging bootloader, dismounting burning flash, and the instrument of using other, can improve debugging efficiency, reducing development cost like this.
Beneficial effect of the present invention is exactly: the starter burning program once after, just no longer change starter.How no matter how hardware adaptor device conversion, can load bootloader by starter and go debug hardware, can avoid causing because of debugging mistake or hardware adaptor problem dismantling that flash removes direct burning bootloader and time of wasting also can be saved the cost of buying simulation research and development device and be reduced cost.
In a specific embodiment of the present invention, its concrete operations comprise step:
1. system for writing and compiling initialize routine starter.bin, the similar general bootloader of this program, but more simplify the main necessary general device of initialization system: cpu/ddr/serial/clock than bootloader; Other devices to integrated circuit board do not operate;
2. in starter, increase the support to serial port protocol, and provide the function that loads bootloader according to serial port protocol.Can pass through this function debugging bootloader;
3. starter.bin is burnt to flash, before starter starts, press certain key as ' K '; After starter starts, whether pushing button according to detecting ' K ' determines whether to need to load bootloader; If have, then by serial ports instrument such as teraterm commonly used bootloader is loaded in the internal memory, make the Bootloader operation, if do not have, then directly from flash operation bootloader;
4. if when loading bootloader from starter, bootloader not operation gets up, failure when some external device of bootloader initialization or initialization function are described, again debugging compiling Bootloader also presses as above method loading bootloader, this saves many times than direct dismounting flash and burning bootloader, has improved efficiency of research and development.
