Im Projektverzeichnis ein Unterverzeichnis linkscripts erstellen (Name muss genau so sein).
In diesem Verzeichnis die Datei memory.ldt erstellen.

folgendes in die memory.ldt kopieren:

 <#--
This linker script will, depending on the MCUxpresso build configuration name
move the memory position of the application start in flash, reduce the flash size accordingly,
change the RAM location and RAM size so that the resulting *.hex file
can be used with the Selfbus PC_updater_tools -fileName paramter.
(https://github.com/selfbus/software-arm-lib/tree/master/Bus-Updater/PC_updater_tool)

If the build configuration name starts with "Flashstart 0xWXYZ"
it changes flash start to 0xWXYZ (WXYZ application start address in hexadecimal),
move RAM start by +0x100 and reduze RAM size accordingly.

E.g. from build configuration name 'Flashstart 0x3000 Debug o8 4t' 0x3000 will be extracted.
On a LPC1115 MFlash64 flash start will be changed to 0x3000 and flashsize reduzed to 0xD000.
RamLoc8 start will be changed to 0x10000100 and size reduced to 0x1f00

This file must be placed into a subfolder named "linkscripts" of your project (application).
The subfolder MUST be named "linkscripts", otherwise MCUxpresso won't find the file and build the project
as normal.

In MCUXpresso eine neue Buildkonfiguration erstellen, dabei ist wichtig, dass der Name der neuen Buildkonfiguration mit Flashstart 0xWXYZ beginnt.

Wobei die 0xWXYZ für die hexadezimale Startadresse der Applikation steht und bei Bedarf auch geändert werden kann.
Beispiel für einen gültigen Konfigurationsnamen: Flashstart 0x3000 Debug o8 4t ha
