Fig. 1 is the described embedded device embedded software update of an embodiment of the invention method flow diagram;
Fig. 2 is the described embedded device structural representation of the embodiment of the invention.
Embodiment
Below, describe the present invention in conjunction with the accompanying drawings.
As described in Figure 1, present embodiment provides a kind of update method of its embedded software of embedded device, and this method comprises:
Step 10 is to the embedded device start that powers on; Perhaps, on this equipment, be provided for upgrading the renewal button of embedded software, start this button, can carry out embedded software update this equipment.
Present embodiment adopts to the power on mode of start of embedded device and opens the renewal of embedded software.
Step 11 starts the boot Bootloader that is preset in advance in the embedded device;
Step 15, the system software that whether has band to upgrade in the detection of stored card is if having, step after then carrying out: read described system software to be updated, and it is copied to system software preset memory areas territory, if do not have, then carry out step 20, operation embedded device original system software;
Step 19, the system software after operation is upgraded.
In the present embodiment, the renewal interruption that causes in order to prevent from when carrying out system software update to occur fault such as outage, therefore, after step 11, increased step 12～step 14, accordingly, above-mentioned steps " is read described system software to be updated, and it is copied to system software preset memory areas territory " also split into step 17 and step 18.Specific as follows:
Step 12 reads the update mode sign in the embedded device;
Step 13 judges whether described update mode sign is " renewal is finished " sign, if then execution in step 14, if not, then execution in step 15;
Step 14 judges whether anti-false triggering button is pressed, if then execution in step 15, if not, then execution in step 20, operation embedded device original system software;
Step 15, the system software that whether has band to upgrade in the detection of stored card, if having, then execution in step 16, if do not have, then execution in step 20 is moved embedded device original system softwares;
Step 16, display reminding information on embedded device, prompt system will carry out software upgrading;
Step 17 reads system software to be updated, and the update mode sign is set to " upgrading " sign simultaneously;
Step 18, duplicate system software to be updated from storer, it is duplicated be placed into the storage area that the system software on the embedded device presets, SRAM (Static Random Access Memory for example, static memory) in, the update mode sign is set to " renewal is finished " sign simultaneously;
Step 19, the system software after operation is upgraded.
As seen, by in embedded device, inserting boot, and system software to be updated is deposited in the storage card of embedded device, user oneself just can realize the renewal of embedded device software, this has also brought convenience for research and development, manufacturing, after sale service.
