Abstract
The invention discloses a method for upgrading embedded system software, which comprises the following steps of: operating a system guide program; judging whether a system is needed to be upgraded or not by using the system guide program; reading an upgraded file code from a memory card to a system memory when the system is needed to be upgraded; and ensuring that a system processor jumps to the system memory to execute the upgraded file code. The upgrading method has the advantages of high flexibility and upgrading efficiency.
Description
Technical field
The present invention relates to the embedded system field, particularly a kind of method of updating embedded system software.
Background technology
Embedded system has been widely used in the various fields such as the communications field, testing apparatus, Medical Instruments and information household appliances at present.Along with user's demand constantly increases, the function of embedded system is also more and more abundanter, thereby the software version of system is also more and more, needs frequent upgrading, to satisfy the function that increases.
Present general upgrading mode major part is the actions such as position, the old system of backup that realize the validity check of new procedures in the boot program, new procedures is updated to existed system, thereby reaches the purpose of upgrade-system.If but the program point layout of system or the variation of having introduced new upgrade mode generation essence, so old boot program just can't realize, boot program that can only be new and old.Thereby cause the dirigibility of system upgrade not high, and upgrade step is loaded down with trivial details.
Summary of the invention
The purpose of this invention is to provide a kind of upgrading method of updating embedded system software flexibly.
For solving technical matters of the present invention, the invention provides a kind of method of updating embedded system software, it comprises: the step of operational system boot; System bootstrap routine need to judge whether the step of upgrading; When system need upgrade, from storage card, read the step of upgrade file code to Installed System Memory; And system processor jumps to Installed System Memory to carry out the step of described upgrade file code.
Compared with prior art, the method for updating embedded system software of the present invention does not rely on the limitation on the boot function of original curing, and dirigibility is strengthened greatly; In addition, utilize the upgrade code program file of storage card can directly upgrade the boot of original curing, reduce intermediate steps, improved the upgrading efficient of system.
Description of drawings
Fig. 1 is the process flow diagram of method for updating embedded system software of the present invention.
Embodiment
This method is utilized a system bootstrap routine (boot program), import according to the user and to trigger or to be checked through that to authenticate to software systems imperfect, thereby the code that directly reads the ROMPaq file in the storage card card is in RAM, jump to this section of RAM relaying reforwarding row program in machine code then, allow upgrade function that unlimited expansion is arranged.
See also Fig. 1, be the process flow diagram of method for updating embedded system software of the present invention, the step of this method is as follows:
Step S1: system start-up, operational system boot (boot program);
Step S2: judge whether system needs upgrading;
The process of judging upgrading is as follows: at first the boot program detects user whether by button or GPIO (General Purpose Input/Output that certain is specific, general I/O) expression needs initiatively upgrade-system, if do not have, the validity by mode checks code system such as whether version number correct then, if it is invalid, then showing needs upgrading, enters step S3; If effectively, illustrating does not need upgrading, then enters step S4, operational system;
Step S3: from storage card, read ROMPaq to Installed System Memory RAM;
Check whether the ROMPaq file in the storage card exists, if exist and passed through validity check, so with this document copying in RAM;
Step S5: carry out ROMPaq; Control PC pointer, system processor jumps among the RAM that preserves the ROMPaq file and carries out, and this program file will be carried out operations such as upgrade-system, boot program, finishes remaining upgrade step.
Compared with prior art, the method for updating embedded system software of the present invention does not rely on the limitation on the boot function of original curing, and dirigibility is strengthened greatly; In addition, utilize the upgrade code program file of storage card can directly upgrade the boot of original curing, reduce intermediate steps, improved the upgrading efficient of system.
Claims (4)
1. the method for a updating embedded system software is characterized in that comprising:
The step of operational system boot;
System bootstrap routine judges whether system needs the step of upgrading;
When system need upgrade, from storage card, read the step of upgrade file code to Installed System Memory; And
System processor jumps to Installed System Memory to carry out the step of described upgrade file code.
2. the method for updating embedded system software according to claim 1, it is characterized in that, in the described step that judges whether to upgrade, adopt detect user whether by button or GPIO that certain is specific represent needs initiatively upgrade-system need to judge whether to upgrade.
3. the method for updating embedded system software according to claim 1 is characterized in that, in the described step that judges whether to upgrade, adopt to detect modes such as version number is whether correct and need to judge whether upgrading.
4. the method for updating embedded system software according to claim 1 is characterized in that, when the judgement system does not need to upgrade, moves this system.
