After DFU (OTA) successful firmware update, device needs to power cycle

[TigerD]

Hi, 

For both (nRF52840 / nRF52832 ), with SDK version nRF5_SDK_15.3.0_59ac345

I am using Secure_Bootloader in the eample folder:

    nRF5_SDK_15.3.0_59ac345/examples/ble_peripheral/ble_app_buttonless_dfu

DFU is successful. But after firmware updated, the device needs to be power cycled to run. Otherwise, it stuck.

What needs to be done, in order to reset the device after update?

Thank you,

David

Also, in my application code, main.c,  I commented out:

//NRF_POWER->GPREGRET = BOOTLOADER_DFU_START;

//peer_manager_Init(); 

The OTA firmware update still works. I don't know what functional roles for both lines of code?

Is it safe if they are commented out? I tested it seems to work with or without.

Hi David,

TigerD said:

//NRF_POWER->GPREGRET = BOOTLOADER_DFU_START;

I could not find this code in the main.c of Buttonless DFU Template Application example. Which example are you using?

Power.GPREGRET register is the general purpose retention register. BOOTLOADER_DFU_START is a magic number to signal that the bootloader should enter DFU mode because of the signal from Buttonless DFU in the main app.

//peer_manager_Init(); 

peer_manager_Init() is used to initial Peer Manager which manages BLE security (encryption, pairing, and bonding). Please see the Peer Manager Usage section for the detail.

Amanda,

Sorry, I must have copied from other places. 

But my main question is Bootloader seems not resetting after firmware update. That should be in the securebootloader, right? The secure_bootloader is the one under dfu folder.

Any suggestions to what part is missing for not doing software reset?

Thank you,

david

I tested the example ble_app_buttonless_dfu in the folder

  ../nRF5_SDK_15.3.0_59ac345/examples/ble_peripheral

And I tested on the nRF52840 dev board. The firmware is updated through OTA, but it needs to toggle the power switch to run the application.

I looked into the ../components/libraries/nrf_bootloader/nrf_bootloader_app_start.c

there is nrf_bootloader_app_start();

AND in the nrf_bootoader_app_start_final.c , there is nrf_bootloader_app_start_final(),  app_start(), I don't know which function is the last call to jump to application. Or is it possible the settings generated through nrfutil tool is not right. But application can be started from bootloader after power cycle. I believe there is something in the secure_bootloader code, not resetting the CPU (softReset) after successfully updated firmware. It is difficult to debug bootloader. 

Please help on this item.

Thank you,

David

Hi David, 

Did you modify the example of ble_app_buttonless_dfu and Secure_Bootloader?

Did you combine ble_app_buttonless_dfu application, bootloader and softdevice image with the Bootloader settings page?

I would recommend you to go through this blog post in order to get started with our DFU solution: https://devzone.nordicsemi.com/nordic/nordic-blog/b/blog/posts/getting-started-with-nordics-secure-dfu-bootloader.
