Hi,

The correct linker configuration depends on which package variant you are using. The default configuration is for the xxAC variant that has 256K of flash and 32K of RAM. 

Default:

xxAA (256/16):

xxAB (128/16). Note: BOOTLOADER_REGION_START must be changed to reflect new start address

HI,

Thnks i can now see the Dfu Targ in the MCP and connect to it.

but after 1% of upload i got this massage 

any idea why ?

[Vidar Berg]

Have you made any changes to the example apart from changing the linker settings? Please check what the buffer sizes are set to in hci_mem_pool_internal.h to  (RX_BUF_QUEUE_SIZE, RX_BUF_SIZE,  TX_BUF_SIZE).

I only changed it to work with the internal oscillator  

 SOFTDEVICE_HANDLER_INIT(NRF_CLOCK_LFCLKSRC_RC_250_PPM_500MS_CALIBRATION, false);

Thanks, both buffer and clock configuration is correct. Which package variant did you use? I'm wondering if the problem could be related to placement of the m_peer_data variable. Please check the address of where m_peer_data is stored, it's shown in the .map file located in the build folder.

i tried using external oscillator and it worked but only for the first upload if i try again i am falling

The bootloader requires the scheduler so you should change this line:

SOFTDEVICE_HANDLER_INIT(NRF_CLOCK_LFCLKSRC_RC_250_PPM_500MS_CALIBRATION, false);

with this one: 

SOFTDEVICE_HANDLER_APPSH_INIT(NRF_CLOCK_LFCLKSRC_RC_250_PPM_500MS_CALIBRATION, true);
