Data-processing arrangement for updating code in an auxiliary processor memory

A computer-program product for a data-processing arrangement that comprises a main processor and an auxiliary processor, the computer-program product comprising:

• a system-program code that, when loaded into the main processor, causes the main processor, when an application program code needs to be replaced, to write an application-program code into a shared memory, and that causes the main processor to write an address indication, which indicates where the application-program code has been written into the shared memory, into a predefined memory location or that causes the main processor, when the application program code does not need to be replaced, to write a jump instruction having a jump address as an address in the application-program code under which the first code of the most recent version of the application-program code has been previously stored;
• and a startup-program code that, when loaded into a startup program memory, which belongs to the auxiliary processor, causes the auxiliary processor to retrieve the address indication from the predefined memory location and, subsequently, to transfer the application-program code from the shared memory to an application-program memory that belongs to the auxiliary processor or that causes the auxiliary processor to jump to the application-program code, which is present in the application-program memory, according to the jump instruction.
