Secure Bootloader With SES

[rajis]

Hi

 I am using SDK 14.2 secure bootloader with IAR and SES build. My IAR project is working with DFU upgradation but my SES Hex file is not working

Procedure Followed:

 1. Create Privatekey.pem file using nrfutil

2. add publickey in source file of IAR and SES workspace

3. Compile binary

4. load softdevice and bootloader binary in nrf52

5. using nrfutil create Application.zip file of application version 4 ,dfu application.zip is working in IAR bootloader build binary not with ses

Issue facing:

  In nrfconnect,dfu process is going ,and able to see application sent successfully .But nrf52 in bootloader mode itself .it is not switch into application mode. in SES build bootloader. In IAR binary ,application mode and dfu mode switching is working.

Please help me to solve this problem .

Hi,

I've not encountered this problem with SES. Are you testing with the *_debug project (\examples\dfu\bootloader_secure_ble\pca10040_debug)? In that case, can you share the full debug log so I can take a closer look?

Hi

 Please find the  attached  bootloader log in RTT viewer and nrf connect log ..

Hi,

Thanks for the logs. Looks like nrf_dfu.c:_nrf_dfu_enter_check() in bootloader returns true based on line 39-41 which explains why the device becomes "stuck" in DFU mode. Can you add additional log messages to this function and see which one of the checks return true?

Thanks berg .Stuck in DFU mode because of Bootloader button is defined . Now it is working.
