BL653 soft reset fails in sample DFU App

[Ubaid_M]

Hi,

I am running Sample DFU app based on peripheral_lbs suggested by nordic on BL653dvk : https://devzone.nordicsemi.com/guides/nrf-connect-sdk-guides/b/software/posts/ncs-dfu

So far have been able to execute & download the firmware file from mobile app into the bl653 board.

But post 100% firmware file downloading on the board, the nrf connect mobile app starts to validate the image.

During validation, the BL653's connectivity drops with the mobile app & it doesn't reboot.

The logs are stuck until here:

The workspace I am using is as in:

5415.peripheral_lbs_BL653.7z

Please suggest for me to resolve this issue.

Same code I tried on nrf52833dk & it works fine there. So.

Thanks,

Ubaid

Hello Ubaid,

Does it remain in this bad state if you reset the board? It would also be helpful if you could attach a debugger to the board and try to figure out where the program gets stuck. A good start is to see if the program counter (PC) register is in the MCUBoot or application region. 

Thanks,

Vidar

After reset same image boots up well, The device is still in application mode & not in mcuboot.

Mobile app says successfully sent file to BL653 & below are the logs from mobile app:

Hi,

After reset same image boots up well, The device is still in application mode & not in mcuboot.

Does it boot the new application, or the previous version, and is the app functioning normally? It appears that it does from the console log you posted (i.e. BLE connection gets re-established after the reset).

Best regards,

Vidar

Hello Vidar,

Vidar Berg said:

and is the app functioning normally?

The nordic suggested sample DFU app worked for me successfully on BL653, Only change I had to do extra was to add  "CONFIG_MULTITHREADING = Y" into "prj_minimal.CONF" file.

Prior to this, the issue was that BL653 was not soft resetting after successful download of the bin file.

Please help me understand regarding how addition of "CONFIG_MULTITHREADING = Y" into "prj_minimal.CONF" file, solves this soft reboot issue..?

And how come the same code is working fine on nrf52833dvk without the addition of "CONFIG_MULTITHREADING = Y" into "prj_minimal.CONF" file..?

Thanks,

Ubaid

Hello Ubaid,

Could you share your current .config files from <build dir>/zephyr and <build dir>/mcuboot/zephyr so I can have a look? I guess the issue is related to the clock calibration as discussed here:  https://github.com/zephyrproject-rtos/zephyr/issues/40538

The 52833 DK uses the 32KHz by default and therefore does not have a need for periodic calibration.

Best regards,

Vidar
