embodiment
Describe technical solution of the present invention in detail below in conjunction with drawings and Examples.
For this software Auto-matching hardware board method, its objective is in order to realize altogether platform of software, and software altogether the key of platform how to be compatible many boards in a set of source code.In order to reach compatible object, can distinguish hardware board by macro definition, if but cause product software version lengthy and jumbled, just lose more than gain.In linux field, it is three necessary processes that linux board starts that uboot startup, kernel loads and file system start, the present invention directly obtains hardware board information in uboot, and board information is run through to whole device start operational scheme, equipment is distinguished no matter can realize hardware board in that flow process like this.
As shown in Figure 1, embodiment adopts linux uboot environmental variance to kernel transmission plate card information, then offers system software and read voluntarily and resolve coupling software corresponding to hardware board and complete relevant configuration.Concrete described hardware board Auto-matching is realized and being comprised the following steps,
Step 1, the unloading phase of uboot, read CPLD (Complex Programmable Logic Device, CPLD) boardtype register(release type register), pcbversion register(hardware version register), slotid register(groove bit-identify register) obtain the board information of current hardware, corresponding release type boardtype and groove bit-identify slotid information are remained on to bootargs(boot parameter with the form of character string) in environmental variance;
Under uboot, can read boardtype register, the pcbversion register of cpld, the value of slotid register, obtain the information of hardware board, in the time that the register value getting can match known board type, after uboot customizes configuration, proceed kernel(kernel) and rootfs(file system) load, start otherwise can enter acquiescence board configuration mode.
Accompanying drawing 2 has provided uboot and has obtained the preservation of board information and conveying flow figure, board starts in the initialized process of ram (random access memory) at uboot, read three cpld registers and obtain boardtype, the value of pcbversion and slotid, mate one by one in known board type according to the value of 3 registers again, find corresponding board type, if match correct board, just can carry out corresponding uboot configuration according to board type, after having configured, boardtype and slotid changed information are kept in bootargs environmental variance, then carry out subsequent step 2, 3, can start successively kernel and file system by environmental variance bootcmd configuration, if do not match known board, have unsuccessful the reporting an error of serially printing output matching board, then directly give tacit consent to board configuration mode, start successively kernel and file system by the mode of acquiescence, instead of execution step 2,3.
Step 2, after uboot has started, enter kernel(kernel) start, kernel can copy the character string of preserving in bootargs to a global pointer variable in the kernel of kernel pointer saved_command_line(linux system, point to a dynamically buffer area address for application) heap address space pointed, the character string information that kernel is preserved saved_command_line address is again by creating proc(pseudo-file system) file is kept at cmdline(command line parameter) in file, this file can be preserved in file system root directory proc file, conventionally be designated as/proc/cmdline file,
The present invention reads the board information that cpld acquires, and in remain in bootargs environmental variance, and bootargs can be created and is kept at by kernel/proc/cmdline file, resolves and calls for software in step 1 with the form of character string.
Accompanying drawing 3 has provided kernel and has obtained the preservation of board information and conveying flow figure, and in the run function (start_kernel) of kernel, kernel copies bootargs to the address space of saved_command_line pointed.After having copied, in kernel code, just can obtain board type by resolving the character string (the board type identification of character string forms) of preserving saved_command_line address, just can carry out the Custom Kernelization configuration of board according to board type, kernel also can load establishment/proc/cmdline file and preserve the information that saved_command_line pointer is preserved again.
Step 3, after kernel has started, start to start rootfs(file system), now can resolve boardtype and the slotid of the current hardware of cmdline file acquisition under proc file, load different software according to analysis result and complete the required configuration of different boards.
