After updating the software with nRFtoolbox, my device doesn't advertising.

[cemalb]

I am working with the secure bootloader example. I copied the firmware zip package to my phone. It contains only application.hex in the package, ​there is no softdevice or bootloader. the software package is installed on my device but afterwards it doesn't advertising. however, it works fine when I install software via the computer using the nRF connect application.

1)After loading the softdevice and application into nrf52 with nRFconnect on the computer, the flash memory image is as follows:

2)After loading the softdevice and bootloader into nrf52 with nRFconnect on the computer, the flash memory image is as follows:

3)This is the flash image after loading the application.hex file with nRFtoolbox.

I think there is a problem after installing softdevice and bootloader and softdevice is corrupted. or there is another problem. What could be the problem I'm having?

Hi, 

Which version SDK/Softdevice are you using?

How do you generate the updated package? Please post the command you are using. 

Do you see the device adverse as DfuTrag after programming the softdevice and bootloader?

Do you see any errors from the bootloader (use _debug version bootloader, you can see the log in segger or RTT view) while/after updating the package?

I am using sdk 15.3.0 and s132.

I am using this command:

2-N5ftrrfutil pkg generate --hw-version 52 --sd-req 0xB7 --application-version 1 --application abc.hex --key-file private.pem app_dfu_package.zip

- Yes,When I press DFU in nRFToolbox, my device appears as DfuTrag.

I don't know exactly how to do this.

Hi, 

You should use the project under nRF5_SDK_15.3.0\examples\dfu\secure_bootloader\pca10040_ble_debug to get the debug log with segger or J-Linker RTT View. Are you able to provide the log? Thanks.

Hi,

I debugged with the pca10040_ble_debug example. Log outputs are as follows:

Hi,

Are you using the unmodified example? 

Can you check if the flow is something like the following:

nrf_bootloader_init() -> nrf_bootloader_fw_activate() which returns ACTIVATION_NONE, due to your log (Can you check whether the switch (p_bank->bank_code) case is NRF_DFU_BANK_INVALID or something else?)

Then when nrf_bootloader_init() returns ACTIVATION_NONE, it should call dfu_enter_check(). Does this return? Is it called?

id: 0x00004002 means NRF_FAULT_ID_SDK_ASSERT.

Hi.
I could not take care of this problem for a long time due to my busy schedule. now I am dealing with this problem again.

I checked what you said.

p_bank->bank_code value is 0x00000000.

Yes, I put a breakpoint there. Calling dfu_enter_check () function after ACTIVATION_NONE.

The fault id indicates that an NRF_FAULT_ID_SDK_ASSERT has occurred somewhere in your code. I'm not sure why this would happen upon connection, but you can read out the assert_info_t struct stored at 0x2000FFB8 to find the line number and file name of where occurred. 

E.g.,

assert_info_t * p_info = (assert_info_t *) 0x2000FFB8 ;
NRF_LOG_ERROR("ASSERTION FAILED at %s:%u",
p_info->p_file_name,
p_info->line_num);
