Fig. 2 is process schematic of the invention.
Specific embodiment
The purpose of the present invention, advantage and feature, by by the non-limitative illustration of preferred embodiment below carry out diagram and
It explains.These embodiments are only the prominent examples using technical solution of the present invention, it is all take equivalent replacement or equivalent transformation and
The technical solution of formation, all falls within the scope of protection of present invention.
The initramfs firmware compiling system based on openwrt translation and compiling environment that the present invention discloses, as shown in Fig. 1, packet
Include sequentially connected file extraction unit, file declustering unit, dilatation unit, synthesis unit, updating unit and generation unit.
The file extraction unit, will be in the kernel file vmlinux of compiling completion for receiving user instructions
.init.data section content is saved into the init_data file comprising the rootfs file compressed.
The file declustering unit is used to the init_data file being split as 3 parts according to two cut-points, wherein
First cut-point is the initial position of the rootfs file compressed, and second cut-point is carried out according to the digit of fixer system
It determines, 3 files are respectively designated as head, body, tail after fractionation, and wherein body file is compressed rootfs text
Part.
The dilatation unit is packaged pressure for receiving rootfs file to be updated, by the rootfs file to be updated
Contracting forms new compressed file, and makes compressed format and file size phase of its compressed format with the body file in S2 step
Together；The kernel for the rootfs file compressed to be carried out to dilatation in compilation process is provided in the dilatation unit
Patch file, the kernel patch is in compilation process, when generating rootfs file, rootfs tail of file is filled specified
Rootfs file after dilatation is compiled into kernel file by the empty file of size, Lai Shixian dilatation, compiling system.
The synthesis unit is used for head file, the tail file in the compressed file of dilatation cellular manufacture and S2 step
Merge and generates new_init_data file.
The updating unit is used for new_init_data up-to-date into kernel file vmlinux
.init.data in section, new vmlinux kernel file is obtained.
The generation unit is used to be packaged to generate by new vmlinux kernel file according to goal systems firmware format and correspond to
Firmware.
The volume for the initramfs firmware compiling system based on openwrt translation and compiling environment that invention further discloses above-mentioned
Process is translated, as shown in Fig. 2, is included the following steps:
S1, the file extraction unit receive user instructions, in the kernel file vmlinux that compiling is completed
.init.data section content saves into the init_data file comprising the rootfs file compressed and sends the file to
Split cells.
The received init_data file is split as 3 parts according to two cut-points by S2, the file declustering unit,
Wherein, first cut-point is the initial position of the rootfs file compressed, and second cut-point is according to the position of fixer system
Number is determined.
Wherein, the digit of the fixer system refers to that target device using the system digit after the starting of this firmware, is compiling
It is preceding it is known that fixer system digit, common have 32 and 64 systems, also, what is saved due to tail is rootfs text
The length of part is saved in 32 systems using 4 bytes, is saved in 64 systems using 8 bytes, therefore works as the firmware system
When the digit of system is 32, second cut-point is fourth from the last byte；When the digit of the fixer system is 64,
Second cut-point is the 8th byte reciprocal.
Formed after fractionation 3 files are respectively designated as head, body, tail, wherein body file is after compressing
Rootfs file, and send the file after fractionation to dilatation unit.
S3, the dilatation unit receive the file after rootfs file and fractionation to be updated, will be described to be updated
Rootfs file is packaged compression and forms new compressed file, and makes the compression of the body file in its compressed format and split cells
Format and file size are identical, when the body file size in the insufficient S2 step of the size of the new compressed file,
0 byte content is filled in the new compressed file；When the size of the new compressed file is greater than the body text in the S2 step
When part size, then compiling failure is assert, because version publication firmware size is floated to a very small extent every time, and compiling
Kernel can be defaulted according to demand reserves certain space, and equally in embedded environment, the space flash is limited, to the big of firmware
Small is also to have the upper limit, for example, existing rootfs size is 17M, can reserve the sky of 27M to rootfs in kernel compiling
Between；Send new compressed file to the synthesis unit.
S4, the new compressed file that the synthesis unit generates the dilatation unit and file split cells in S2 step
Head file, the tail file mergences generation new_init_data file torn open.
S5, the updating unit is by the content update of the new_init_data file into kernel file vmlinux
.init.data section in, obtain new vmlinux kernel file.
New vmlinux kernel file is packaged to generate and be corresponded to by S6, the production unit according to goal systems firmware format
Firmware.
System and method through the invention can reduce disk occupied space: this is because openwrt default compiling ring
Border reaches the space of 20GB, and the system for using this method only takes up space about 4GB.
Also, the present invention supports multiple-limb version to issue parallel: this is because compiling a version using this system only needs
5 minutes are wanted, and is compiled using openwrt and is once at least also required to a few hours, when having multiple versions while issuing, total volume
The time translated compiles efficiency and greatly improves with regard to poor very big.
Meanwhile this busy portable enhancing: this is because original openwrt compiling system reaches after the completion of compiling for the first time
The space of 20G, and can not transplant, developer must respectively compile, and it is time-consuming and laborious, about using occupied space total after this system
4G, and can be operated normally in other translation and compiling environments, no dependence condition.
Still there are many embodiment, all technical sides formed using equivalents or equivalent transformation by the present invention
Case is within the scope of the present invention.
