8.1.4 Delete boot application via SD card
15970
If after the start of a complex boot application the device is overloaded and does not respond any
more to user inputs or login attempts, the boot application on the device needs to be forcibly deleted.
To delete the boot application on the device:
► Disable the write protection of the SD card.
► Create a file named KillBootApp.txt in the root directory of the SD card.
► Insert the SD card into the SD card slot of the device.
► Restart the device.
> Boot application on the device-internal PLC is deleted.
> The file KillBootApp.txt on the SD card is renamed in KillBootApp.rdy.
With this method the following data on the device-internal PLC is removed:
 all files of the boot application
 all CRC files
 directory with web and/or target visualisations
 data in the memory area F-RAM
