發表於 由撰寫發表留言

Following up – Part 1: Bootloader & Application (Click for article link),

We will be focusing on:

Part 2: Combining & merging built files

in this article.

IC: nRF52832
DK: PCA10040 (for nRF52832)
SDK: 16.0.0
Softdevice: s132_nrf52_7.0.1_softdevice.hex
IDE: Keil C
PC: Win 10


Part 2: Combining & merging built files


Step 1. Execute the combine batch file in bootloader (nrf52832_bootloader_setting_merge.bat) and generate file of nrf52832_bootloader_secure_combin_settings.hex :

@echo off
title = [ J-Link Tool ] %CD%
set nrfDir=C:\Program Files (x86)\Nordic Semiconductor\nrf5x\bin
set BS= nrf52832_bootloader_secure_settings.hex
set BL= nrf52832_xxaa_s132.hex
set BSBLCombind= nrf52832_bootloader_secure_combin_settings.hex
set path=%nrfDir%;%path%
pause
echo ———–merge image file——————-
mergehex.exe -m %BS% %BL% -o %BSBLCombind%
pause


Step 2. Create a Final.hex file by 3-in-1 batch file(nrf52832_3in1_merge.bat)
※Note : This hex file is created for the production line to pre-load firmware into modules prior to shipment.

@echo off
title = [ J-Link Tool ] %CD%
set nrfDir=C:UsersuserDesktopNordic BLEnRF5_merge toolsnRF52 bin
set SD= s140_nrf52_7.2.0_softdevice.hex
set BLT= nrf52832_bootloader_secure_combin_settings.hex
set APP= nrf52832_xxaa.hex
set SD_BLT=SD_BLT.hex
set Finalfile=Final.hex
set path=%nrfDir%;%path%
pause
echo ———–merge image file——————-
mergehex.exe -m %SD% %BLT% -o %SD_BLT%
pause
mergehex.exe -m %SD_BLT% %APP% -o %Finalfile%
pause


Step 3. Create a DFU(OTA).zip file of nrf52832_xxaa.zip
※Note : This zip file is created for end device DFU(OTA) implementation.

nrfutil pkg generate –hw-version 52 –sd-req 0xCB –application-version 0xFF –application
nrf52832_xxaa.hex –key-file private.pem nrf52832_xxaa.zip

The DFU OTA zip file will be derived.

※Note :
The “0xCB" appeared in the above DOS code(in red font) is the FWID(Firmware ID) for s140_nrf52_7.2.0_softdevice.hex;
FWID can be found from the soft device documents on the Nordic website.



Step 4: Run DFU OTA (On mobile in this example)


4A. Install the nRF Connect APP on mobile, with DFU OTA file: nrf52832_xxaa.zip. (Download link)


4B. Send nrf52832_xxaa.zip via email to mobile device after combination is done on PC, then download it.


4C. Open nRF Connect APP and run connection;


4D. Execute DFU and select “Distribution packet(ZIP)", thus starting the DFU OTA process.


4E. Start DFU OTA → exit the APP after DFU OTA is completed → restart the mobile device.

Secure DFU OTA for nRF52832 solution modules: Guide to create hex/zip file for implementation – Part 1(Bootloader & Application)

發表於 由撰寫發表留言

Here are the guidelines for users to implement Secure DFU OTA(over-the-air) while using nRF52832 Solution modules. (Click on link for Raytac nRF52832 module series)

IC: nRF52832
DK: PCA10040 (for nRF52832)
SDK: 16.0.0
Softdevice: s132_nrf52_7.0.1_softdevice.hex
IDE: Keil C
PC: Win 10

Below are the guidelines to implement Secure DFU OTA by using Raytac’s nRF52832 modules, SDK16.0.0.
It consists of 2 parts:

Part 1: Bootloader & Application


Part 2: Combining and merging built files (Article link)

In this article, we will be focusing on Part 1: Bootloader & Application.

Bootloader


Path: ..\nRF5_SDK_16.0.0_98a08e2\examples\dfu\secure_bootloader\pca10040_s132_ble\arm5_no_packs
Specifically for nRF52832, programmers need to embed ECC(Elliptic Curve Cryptography) into the bootloader.


Step 1. ’micro_ecc_lib_nrf52.lib’ library can be found in the path below, but we need to boot it up first.


Step 2. Unzip ’micro-ecc-master.zip’ to the below path(create a new “micro-ecc” file first).


Step 3. Run ’gcc-arm-none-eabi-7-2018-q2-update-win32.exe’.


Step 4. Make sure the Environment variables in Win10 are set as below. (Follow the steps 1 to 6)


Step 5. Open DOS → run the “make” command under armgcc path → generate’micro_ecc_lib_nrf52.lib’


Step 6. Add ’micro_ecc_lib_nrf52.lib’ into folder: nRF_micro-ecc


Step 7. An error may occur while building bootloader without a public key:
(Shown in red frames in below screenshot)


Step 8. How to generate the public key file in Bootloader?
A. Visit DOS at path: ..\Python27\Scripts
B. Then execute:

nrfutil keys generate private.pem
nrfutil keys display --key pk --format code private.pem --out_file public_key.c


Step 9. Copy the pk[64] code from (public_key.c) into (dfu_public_key.c)
(Shown in red frames in below screenshot)

※Note: Make sure to save the 3 generated files:
private.pem
public_key.c
dfu_public_key.c


Step 10. Generate the bootloader file: nrf52832_xxaa_s132.hex after re-compiling the code files.

Application


Path:
..\nRF5_SDK_16.0.0_98a08e2\examples\ble_peripheral\ble_app_uart\pca10040\s132\arm5_no_packs
Before building Application code , some amendments need to be made regarding DFU-related settings and code inside Application:


Step 1. Add code in definition in C/C++ :
BL_SETTINGS_ACCESS_ONLY NRF_DFU_SVCI_ENABLED NRF_DFU_TRANSPORT_BLE=1
(Total 3 steps definitions need to be set up)


Step 2. Add the 3 paths shown below in C/C++ to make DFU work.


Step 3. Add the .c files inside red frame in (Screenshots 1 & 2)
and add the 2 groups of (nRF_DFU & nRF_SVC)(Screenshot 4) under Project(Screenshot 3)


Step 4. Add code into main.c file in Application (..\examples\ble_peripheral\ble_app_uart\main.c)
(Please refer to: main.c file at: ..\examples\ble_peripheral\ ble_app_buttonless_dfu)


Step 5.
The code of file: sdk_config.h (..\examples\ble_peripheral\ble_app_uart\pca10040\s132\config\sdk_config.h)
inside Application needs to be modified.


Step 6. Adjust the IRAM1 value in Target after implementing DFU service:
Make sure the IRAM1 Value of *p_app_ram_start is modified from default: 0x20002AD8 0xD528 to
0x20002AE8 0xD518, as shown in the red frame in the bottom right corner.
In this case, the program should run/advertise successfully.


Step 7. Create a file of: nrf52832_xxaa.hex after building application code files.



Step 8. Create a bootloader setting file of nrf52832_bootloader_secure_settings.hex via DOS.
nrfutil settings generate –family NRF52 –application nrf52832_xxaa.hex –application-version 3 —
bootloader-version 2 –bl-settings-version 1 nrf52832_bootloader_secure_settings.hex –no-backup

※Stay tuned for Part 2: Combining and merging built files in the next article, scheduled release in next week(04-Sep-2024).

ANT+ Module by Raytac

發表於 由撰寫發表留言

nRF51422 is the first solution supports both Bluetooth and ANT+, different from pure Bluetooth Low Energy BLE solution, nRF51822 released earlier. The edge cutting technology enable nRF51422 suporting multiprotocol concurrency capable for both Bluetooth Low Energy and ANT+. At the same time Nordic released SDK S310 for nRF51422 which is a combined peripheral BLE and ANT+ protocol stack that supports concurrent operation and all ANT+ features.

When Nordic moved to nRF52, started from nRF52832, the game changed. Even nF52832 still supports ANT+, the technology support such as SDK releasing or developers’ forums, has moved to direct supported by ANT+ Wireless (formerly Dynastream Innovations). Since then, Raytac suggest developers who is interested in ANT+ product still able to select the modules based on core specification and form factor, but access the firmware development support from ANT+ directly. Developers who are interested to know more about ANT+ is encouraged visit ANT+ FAQ support page first for more information about membership, development, resource and certification.

All Nordic nRF52 solutions supports ANT+ feature, developers may refer to below Raytac module map and find what the protocol supports by the symbol stated besides the Nordic solution indication.
