RE: Can't see application running after OTA DFU

Hi Louis,

can you post the linker script of the ble_app_blinky project? If it is the default example, then you will have to modify the FLASH settings to free up space for the bootloader. The default settings reserves the entire flash from 0x26000 (end of SD) to 0x80000 ( end of flash)

MEMORY
{
  FLASH (rx) : ORIGIN = 0x26000, LENGTH = 0x5a000
  RAM (rwx) :  ORIGIN = 0x200022b8, LENGTH = 0xdd48
}

/* Modify to the following to free up space for the bootloader, 
/ which starts at 0x78000. Hence, the FLASH LENGTH must be 0x78000-0x26000= 0x52000
*/

MEMORY
{
  FLASH (rx) : ORIGIN = 0x26000, LENGTH = 0x52000
  RAM (rwx) :  ORIGIN = 0x200022b8, LENGTH = 0xdd48
}

Best regards

Bjørn
