Im looking at the Secure bootloader source in SDK v13.0.0 and nrf_bootloader_app_start() should set the SoftDevice vector table, i.e. call sd_softdevice_vector_table_base_set() and not nrf_dfu_mbr_vector_table_set().

After flashing all are fine. If i upgrade the Firmware With dfu then it is written after the Firmware is send With ble. the Whole System is broken when the Code (upper) is reached. After that the mbr page is no longer r clear. Then i cant start the bootloader anymore. If i clear mbr page i can get Into bootloader again. the problem might be the nrf_dfu_mbr_vector_table_set function, but why. the firmware is written just fine with dfu (log files).

It is weird that the MBR settings page is written to when you compile the bootloader project in Eclipse since the mbrParamsPage is set to NOLOAD, i.e.

/* Place the mbr params page in flash. */ .mbrParamsPage(NOLOAD) : {

} > MBR_PARAMS_PAGE

Or are you reading out the MBR settings page after you have flashed the bootloader to your device?

Yes the linker script from debug from dfu sample folder

Im not that familiar with managed make, but I assume that you have to specify some kind of linker script?

I checked the mbr page of the two different versions. the difference is, that in eclipse compiled bootloader the page changed. i added the file on top. in sample bootloader thre is only 0xFF in the file.

Okay i got news. it seems to be code:

NRF_LOG_DEBUG("Setting MBR vector table base: 0x%08x\r\n", start_addr);

err_code = nrf_dfu_mbr_vector_table_set(start_addr, true);
if(err_code != NRF_SUCCESS)
{
    NRF_LOG_ERROR("Failed running nrf_dfu_mbr_vector_table_set\r\n");
    return;
}

in void nrf_bootloader_app_start(uint32_t start_addr)

with a while befor that code, i can restart the bootloader by holding the button. if the bootloader reach that code, i am unable to get into bootloader once again with button press.

additionally the code size of the eclipse compiled project is 35004 bytes, while the codesize of the sample from makefile is about 34500 but in the linker script is the flash size defined by 0x9000 so idk why it is broken after flashing the firmware

Yes it Works fine.

So if you compile the bootloader project in the SDK using the supplied Makefile you're able to perform a successful Application DFU?

yes it is the compiled .hex file in the sdk sample folder for pc ..40 board. i compiled it with the makefile, all went fine.

So when you say: "if i use the .hex from the sample folder, all works fine." do you mean the bootloader hex in the sample folder?

Okay now i got two logs. One from the sample Bootloader and one from the eclipse compiled one.

Bootloader Eclipse Compiled.log Bootloader Sample Nordic.log

they both seem identical

No its the dfu_test_app_hrm_s132.zip from the sample folder of dfu

Have made your own application firmware image using nrfutil ? If yes, can you post the commands you used to create the .zip file and which version of nrfutil that you're using?
