I'm having trouble starting my application after power cycling after flashing it with the DFU app.

Resolved. I had not included all compiler and linker flags into my ecplise project (I'm not using the makefile). I looked at the makefile and included all missing flags. Now the bootloader works fine.

Now I tested with a very simple application that only turns on a LED and then runs a while(1) loop.

It also works just after it has been downloaded to the board through the iphone app. But when I restart the board it wont start and the bootloader is also dead.

Could it be some incompatibility with S130 V2.0.0 SoftDevice ?

I added:

SEGGER_RTT_printf( 0, "pstorage_flash_page_end = 0x%" PRIX32 "\n", NRF_UICR->NRFFW[0] );

It says just after reprogramming:

pstorage_flash_page_end = 0x3C000

I suspected that pstorage corrupts the DFU bootloader but this (I think) proves it doesn't.
