Embodiment
For the purpose, technical scheme and the advantage that make the embodiment of the invention is clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
The present invention is by dividing the memory headroom that is used in the simulation flash memory in internal memory; in hard disk, create the power down protection file of simulation flash memory; thereby realized utilizing internal memory and fixed disk file simulation flash memory to carry out the program development debugging; adopt true flash memory to carry out the method for program development debugging compared to existing technology; exploitation debugging speed of the present invention is faster, and realizes simple.
As shown in Figure 1, the exploitation adjustment method of embodiment of the invention application program may further comprise the steps:
In step S101, in internal memory, divide the memory headroom that is used in the simulation flash memory, the flash memory space equal and opposite in direction that the size of this memory headroom and application program will be visited;
In hard disk or other Nonvolatile memory devices, create the power down protection file (as the file of file flash.dat by name) of simulation flash memory, and write initialized dummy status data to memory headroom by this power down protection file, make the original state of memory headroom when developing for the first time debugging for empty; Certainly, also can be but directly write the dummy status data to memory headroom not by the power down protection file, so the power down protection file also can be created after the application program first time has been debugged;
In step S102, during application program launching, check whether the power down protection file that is used to simulate flash memory in the hard disk exists, and does not create in step S103 if do not exist then, continues execution in step S104 if exist;
In step S103, in hard disk, create the power down protection file of simulation flash memory, then execution in step S104.
In step S104, in the memory headroom that distributes, develop debugging utility, it mainly comprises following three kinds of operations (please in the lump with reference to figure 2):
Read operation: when application program need be visited flash memory, reading of data from memory headroom; When if application program need be visited flash memory once more after system's power down, the file system of internal memory by PC read the content of the file of simulation flash memory power down protection in the hard disk in the corresponding memory headroom, application program can be from memory headroom reading of data.
Erase operation: the data of preserving when flash memory dispatches from the factory are complete 1, just 0xFF is the original state of all bytes, this moment, the inside, space of this byte write any data in the past, in case this byte has been write as 0x00, adopt write operation just can't make it become the data of other any byte, just become 0xFF after having only monoblock to wipe, so the data that the memory headroom of simulation flash memory be wiped the needs of correspondence all are set to 0xFF when wiping.
Write operation: write operation can only become 0 from 1 with data bit in the real flash memory, and can not become 1 from 0, if requiring certain flash block can use again, must carry out erase operation and the content of whole flash block could be become 1 from 0, write operation to true flash memory is to cause the overall slower most important reason of the true flash memory of application access, real flash drive all must write four earlier when writing the data of each, the data that the programming byte of five byte instructions could will write are delivered on the data bus of flash memory, also to wait end check results to be programmed afterwards, will go up tens times slowly so the velocity ratio that writes is read; And the embodiment of the invention only need judge whether the byte of the data in the corresponding memory headroom was 0xFF entirely before assignment, then can think if not 0xFF to write failure, and can point out mistake this moment, if 0xFF can be defaulted as and write success;
In step S105, for the memory headroom that makes the simulation flash memory has the function of outage memory, before application program withdraws from, the content of the memory headroom of the correspondence file system by PC is write the power down protection file, when treating the initialization of next application program debugging, the data in the power down protection file are read memory headroom again; The situation that can also cause the flash memory space content to be damaged with the sudden power of simulation embedded system to power down protection file write error data in addition is with the function of the automatic restoring user data of start of test application.
For the exploitation adjustment method that proves embodiment of the invention application program fast than prior art speed, the method test log flash memory file system (JournallingFlash File System, the embodiment of garbage reclamation function JFFS) that adopt the true flash memory and the embodiment of the invention below will be provided.
JFFS is a kind of Journaling File System of increasing income, be suitable for being placed on the flash chip, its garbage reclamation functional requirement be no more than under the situation of power system capacity that flash memory space wants can be recycling, as follows successively such as operation in the flash memory space of a 1.5M byte capacity to a 1M byte file: create, write the 1M byte content, close, delete, create again, write the 1M byte content ..., so repeating will to guarantee to circulate, flash memory still has living space and can utilize after 1000 times.If on real flash memory, the flash memory storage sheet of joining S29GL064A90T such as the ST5100 chip, move test and needed to surpass 10 hours time, and adopt the method for the embodiment of the invention owing to adopt internal memory simulation flash memory, the speed of reading and writing and erase operation is all very fast, and test only spends the time less than 1 minute.
