Definitions
- the invention relates to a method for software update of an electronic device, in particular the trigger of low-voltage circuit breakers, according to the preamble of claim 1.
- test equipment but it can also be executed as internal functions.
- the problem is that the updated firmware itself can not determine whether this test has actually and successfully been carried out so as to ensure safe operation of the circuit breaker.
- the object of the invention is to ensure a safe operation of the circuit breaker even after a software update.
- the solution envisages that the updated software copied into this memory area is checked by means of an external test device, that the test device writes error clearing into the non-volatile memory area and the updated software from the electronic device is only started if the error clearance for the updated software is present.
- This ensures that the (prescribed) check of the electronic device after a software update is really carried out.
- This makes a software update much safer and more reliable even for security-relevant devices.
- such an update can also be carried out by the customer without special knowledge and training.
- This is useful because the majority of electronic releases of low-voltage circuit breakers are equipped with non-volatile memories (EEPROM, FLASH and buffered RAM).
- the idea of the invention is to use a portion of this memory to detect the successful verification of the device by an external test device.
- the electronic device can also check the error clearing cyclically.
- Security can be increased if the memory area is overwritten with the error clearance of the updated software when copying, or if the memory area for storing the error clearance at the beginning of the software update is overwritten with a predetermined value.
- the single FIGURE shows a trigger 1 of a low-voltage circuit breaker (not shown itself) in a schematic representation.
- the trigger has a non-volatile memory 2, 3, wherein the non-volatile Spei- rather 3 is the firmware memory 3, so the memory area in which the operating software (firmware) 3a is stored to be updated.
- the figure shows an external storage medium 4 (e.g., a floppy disk) on which a current firmware 4a is stored.
- the updated software 4a is transferred from the external storage medium 4 into the firmware memory 3, which is schematically represented by the arrow 5.
- an external test device 6 is connected to the trigger 1, which checks whether the updated firmware 3a has been stored correctly and without error in the firmware memory 3. The test by the external test device 6 is in the
- FIG. 8 Figure schematically represented by an arrow 8. If there is a match, ie firmware 3 a that has been updated without error, a fault-free identifier K is entered into nonvolatile memory 2 in which an identifier memory 7 is reserved for this purpose only.
- the error clearing K is overwritten in the identification memory 7 after determination of freedom from errors with a current error clearance K, which, for has the current date.
- the identification memory 7 it is also possible for the identification memory 7 to be overwritten first with a predetermined non-recognition value L at the beginning of the software update and then with the error-free identification K after the firmware update has ended.
- the query of error clearing K can also be cyclic.
