Abstract

A method is described that can be used to apply mass-produced control units without special application tools. In this context, a data record that is to be applied from a first memory area of a flash memory is copied over to a second memory area of the flash memory. The data that are to be applied are updated in sections in a RAM and are then written back to the second memory area. The applied control data record is finally copied back to its original positions in the first memory area.
