If you look at the documentation that comes with the SDK there is a section in the Examples for the DFU bootloader. One of the sections details the DFU Keil project and shows how to set the IROM1 address. If you pick a lower address than the one they show, you will increase the memory your bootloader can have. Just be sure to keep it aligned to the 1K page boundary.

There is no direct limitation of how much space the DFU bootloader can take other than you need to leave space for your application. You need to decide what your trade offs are.

I did not know how to add more space for the bootloader project.

Can you point me to documentation or an example how to configure and add more space to the bootloader project. Also what are the limitations on how much space can be added to the bootloader project.

If you really need the DTM test in the bootloader couldn't you just allocate more space for the bootloader project configuration?

That said, the way we enter DTM mode is that our application FW checks a pin at the beginning of initialization. If it is pulled low we enter the DTM, if not we boot our normal application much like you suggest above.
