Tutorial on setting up the bootloader for nrf52832 in IAR

[Alex_Golubev]

Hi.

 

I' m using nRF52832, SDK v15.0.0, S132.

 

I'm want tutorial how make bootloader DFU in IAR.

 

How I make bootloader DFU for nrf52832 in IAR?

[bjorn-spockeli]

You can use nRF Connect for Desktop or nrfutil on a PC to perform DFU. We also have the nRF Connect for Mobile app for Android and iOS, which allows you to perform DFU from a mobile device.

Me's need step by step guide, getting started with Nordic's Secure DFU bootloader.

Hi Alex, I recommend that you follow this tutorial

Hi.

I readed tutorial but I have questions.

I can't start ble_app_buttonless_dfu. I get erroor "NRF_BREAKPOINT_COND".

What do I do wrong?

[bjorn-spockeli]

This means that one of the APP_ERROR_CHECK checks are asserting. Take a look at the call stack and try to see which function that generated the assert. 

[Alex_Golubev]

I look call stack. 

I got error when function call APP_ERROR_CHECK(err_code);. 

[bjorn-spockeli]

YEs, so its ble_dfu_buttonless_async_svci_init that returns a non-zero error code. This is usually due to the bootloader not being flashed to the nRF52. Compile the bootloader example and flash it to the nRF52 in addition to the buttonless dfu example and the S132 softDevice. See the documentation on the bootloader example.

I did the secure bootloader DFU. I attained step 8 in document.

I instal softdevice and secure bootloader to flash nRF52832. After make the ble_app_buttonless_dfu start download and debug but program not start.

If install only softdevice and buttonless dfu then I got error "No bootloader was found".

If install softdevice and bootloader after buttonless dfu then I got not start programs.

Although security bootloader work.
The verification was performed in the following steps:

E1. Generate new firmware.

E2. Generate new DFU .zip package.

E3. Switch the device to DFU mode, do DFU update and verify new image is running.

Help me

[bjorn-spockeli]

If you flash SoftDevice, Bootloader and the Buttonless DFU application, then the device should start in DFU mode. If you want the device to run the application, then you need to generate a bootloader settings page and flash that along with the SD,BL and App. 

See https://github.com/NordicSemiconductor/pc-nrfutil#generate-2 on how to generate the settings hex file.

Thanks bjorn-spockeli. 

I get new problem. I mayn't build progect in IAR. Progect  Buttonless DFU.

I get errors:

[bjorn-spockeli]

nrf_dfu_peer_data_t is defined in nrf_dfu_types.h - Make sure that you have added this in the include path in IAR ( the file is located in components\libraries\bootloader\dfu) 

nrf_dfu_set_peer_data_svci_async_t is defined when NRF_SVCI_ASYNC_FUNC_DECLARE(NRF_DFU_SVCI_SET_PEER_DATA, nrf_dfu_set_peer_data, nrf_dfu_peer_data_t, nrf_dfu_peer_data_state_t); is called nrf_dfu_ble_svci_bond_sharing.h

I add file \libraries\bootloader\dfu figure IAR error_1.

I include in main.c following libraries:

#include "nrf_dfu_ble_svci_bond_sharing.h"
#include "nrf_svci_async_function.h"
#include "nrf_svci_async_handler.h"

figure library nrf_dfu_ble_svci_bond_sharing.h

figure library nrf_svci_async_function.h

Errors remained.
