Abstract
The invention provides a program debugging method and a program debugging system in an optical network unit (ONU) system. The method and the system are applicable to a Linux system. The program debugging method in the ONU system comprises the following steps: controlling the ONU after being powered up and started to stay at a command line stage; using a modification command to modify a starting configuration parameter in a starting loading system of the ONU; and after the modification of the starting configuration parameter is finished, using a resetting command to restart the ONU so that a network file system automatically mounted by the ONU is a root file system to carry out program debugging. The image burning process is omitted, so that the debugging and testing of the ONU become easier.
Description
Technical field
The invention belongs to communication technical field, relate to a kind of ONU system, particularly relate to the program debugging method in a kind of ONU system and system.
Background technology
Debugging method is the process finding and remove software failure root.At ONU (OpticalNetworkUnit, optical network unit) research and development of software in, nearly all adopt the same method, namely in source code, need the place of debugging to add a large amount of printf or printk statements, then be compiled as image, be burnt in ONU plank afterwards, carry out operation and detect, thus utilize the correctness of the information determining program printed in serial ports, to reach the object of debugging.
For the means of code debugging in ONU system, said method is the most also effective method.But it has a very large drawback, when that is debugged exactly or verifies a thing, most of the time has spent in the process of compiling and burning.If an amendment page or some numerals of program or symbol, developer must recompilate code engineering, is then burnt in ONU plank and just can verifies result.And the information of printing is limited, the place only having developer to recognize has added type information, and it just has information to input.So how to save the time of code debugging in ONU system, and making the process of debugging and verification easier, is the major issue being badly in need of in current ONU research and development of products solving.
Summary of the invention
The shortcoming of prior art in view of the above, the object of the present invention is to provide the program debugging method in a kind of ONU system and system, for solving the program debugging method problem that spended time is longer in compiling and burning in existing ONU system.

Described copy module 540 is connected with described configuration module 530, enter local command and be about to the first file copy in the root directory of described TFTP service system, to power up the ONU after startup loads described linux system from described root directory kernel mirror image by network.
Described control module 550 is connected with described copy module 540, described control module controls the ONU after powering up startup and rests on the order line stage, use the startup configuration parameter of c order amendment Bootloader, after described startup configuration parameter has been revised, reset order is used to restart described ONU, so that network file system(NFS) is the root file system of self described in the automatic carry of described ONU.
After the kernel of described linux system powers up operation, the file directory carry that described linux system utilizes CPE to be shared by described needs by network is at the root directory of self, so that the internal memory that the relative program of file directory that described needs are shared by described CPE calls in self runs.
A kind of specific implementation process of the program debugging method in the ONU system described in the embodiment of the present invention is:
1) installed on the LINUX system PC of debugging ONU product and opened TFTPserver and NFSserver service, having guaranteed the operation that debugged program can be correct.
2) the share directory configuration file of nfs server (being generally speaking /etc/exports file) is found, use vi or other text compiler to open this share directory configuration file, then the file directory needing to share and priority assignation are written in this share directory configuration file.Such as :/opt/bcm963xx/targets/96358GW/fs192.168.1.* (rw, no_root_squash)/opt/bcm963xx/targets/96358GW/fs " for needing the catalogue of shared or carry.CPE powers up startup, after kernel gets up, CPE to be shared by these needs by network or the catalogue carry of carry is its root directory, and all programs (except kernel) run afterwards are all to share from this or the catalogue of carry is called in CPE internal memory and run.Wherein, " 192.168.1.* " be access control of authority, represent that the host of all 192.168.1. network segments can access this catalogue, " * " number be represent 0 ~ 255 Any Digit.Last " (rw, no_root_squash) " represents the access limit of this catalogue, be that the loom of this catalogue of statement carry can be read and write arbitrarily this catalogue here, and authority is equivalent to root.
3) in Linux session, exploitation catalogue is entered, as :/opt/bcm963xx.Then run makemenuconfig order, compiling configuration is carried out to project.The compiling of amendment is needed to be configured to:
A. the Profile of current use is loaded into;
B. select Rootfilesystemselection option, SQUASHFS is revised as NFS;
C. select Driverselection option, find Ethernet item, then <M> is revised as <*>;
D. amended Profile is preserved;
4) the whole engineering below exploitation catalogue, all clean is once.
5) amended Profile is just now used now to carry out the compiling of whole engineering.
6) local command line is entered, then by the root directory of bcm963xx/targets/96368GW/vmlinux file copy to TFTP, as :/tftproot catalogue.After ONU starts, ONU will load linux kernel mirror image with file directory by network from this.
7) power up startup ONU plank, then make ONU plank rest on the order line stage, use the startup configuration parameter of ' c ' order amendment Bootloader.Use after having revised reset order to restart ONU plank, restart rear CPE and TFTP agreement will be used to obtain kernel mirror image from Host machine call in CPE internal memory, then run this kernel mirror image.Kernel has started, and automatic carry NFS file system is its root file system by ONU plank, and whole system has also just been got up.
The present invention has broken away from the process of burning image, the debugging of ONU and test is become and is more prone to.Compared with best prior art, the invention has the advantages that without the need to the image of compiling is burnt on ONU plank, when have modified in code somewhere after, only need to compile, then restart ONU and just can realize having debugged.
In sum, the present invention effectively overcomes various shortcoming of the prior art and tool high industrial utilization.
Above-described embodiment is illustrative principle of the present invention and effect thereof only, but not for limiting the present invention.Any person skilled in the art scholar all without prejudice under spirit of the present invention and category, can modify above-described embodiment or changes.Therefore, such as have in art usually know the knowledgeable do not depart from complete under disclosed spirit and technological thought all equivalence modify or change, must be contained by claim of the present invention.
