My goal is based on SDK16.0.0 and s132_7.0.1 softdevice to achieve BLE DFU (requires binding) and UART DFU work at the same time,
I have combined the 'secure_bootloader_uart' and 'secure_bootloader_ble' in the SDK according to the guidence on DvZone, but
that was 3 years ago The article does not match in some places.
Code path:
github.com/.../BLE-Nordic
Project path:examples\dfu\secure_bootloader\pca10040_uart_merge_ble
STEP:
- IDE: uVision V5.23.0.0, nRF_DeviceFamilyPack 8.29.0, CMSIS 5.0.1.
- Added relevant files under BLE DFU project to UART DFU project.
- To resolve errors and warnings, move the nrf_error.h, nrf_nvic.h, nrf_sdm.h, nrf_soc.h files in the \components\softdevice\s132\headers\ folder to the \components\ folder.
- Modified IROM1 configuration Start: 0x70000 Size: 0xE000
- Copy the ble settings in sdk_config.h under BLE DFU Project to sdk_config.h in uart DFU Project.
- After compilation, merge the nrf52832_xxaa_mbr.hex , hrs_application_s132.hex and s132_nrf52_7.0.1.hex files with the following instructions:
nrfutil.exe settings generate --family NRF52 --application hrs_application_s132.hex --application-version 3 --bootloader-version 2 --bl-settings-version 1 bootloader_settings.hex
mergehex.exe --merge nrf52832_xxaa_mbr.hex s132_nrf52_7.0.1.hex --output production_final1.hex
mergehex.exe --merge production_final1.hex hrs_application_s132.hex --output production_final2.hex
mergehex.exe --merge production_final2.hex bootloader_settings.hex --output production_final.hex - Download to the chip through the following instructions:
nrfjprog -f NRF52 --eraseall
nrfjprog -f NRF52 --program "production_final.hex" --verify
nrfjprog -f NRF52 --reset
PROBLEM:
- After the download is completed, LED1 flashes, indicating that the bootloader jumps normally, you can see NORDIC_HRM through nRF Connect and can connect.
- Hold down BUTTON4 and RESET BUTTON and release at the same time, LED1 and LED2 are on, which is abnormal (LED1 and LED3 are on in the official SDK demo).
- Use "nrfutil dfu serial -pkg hrs_application_s132.zip -p COM4 -b 115200" instruction to update, and the last error message is "No ping response after opening COM port".
- The Bluetooth device with the DfuTarg name cannot be searched with the mobile phone.
