Hi:
I use sdk nRF5_SDK_17.1.0_ddde560. bootloader use examples\dfu\secure_bootloader\pca10056_uart_debug.
It cann't enter the application.
But If I use examples\dfu\secure_bootloader\pca10056_s140_ble_debug.
It can enter the application.
Except for the bootloader, their other applications, dfu_ppublic_key, and softdevice are the same.
hi:
nrfutil settings generate --family NRF52840 --application spectrumWear_v008\EventSystem.hex --application-version 3 --bootloader-version 2 --bl-settings-version 1 middle\settings.hex
mergehex.exe -m s140_nrf52_7.2.0_softdevice.hex spectrumWear_v008/EventSystem.hex -o middle/sd_app.hex mergehex.exe -m middle\sd_app.hex spectrumWear_v008/bootloader_uart.hex -o middle/sd_app_boot.hex mergehex.exe -m middle\sd_app_boot.hex middle/settings.hex -o spectrumWear_v008/spectrumWear_all.hex
nrfjprog.exe --family NRF52 --eraseall nrfjprog.exe --family NRF52 --program spectrumWear_v008\spectrumWear_all.hex nrfjprog.exe --family NRF52 --verify spectrumWear_v008\spectrumWear_all.hex nrfjprog.exe --reset
It cannot jump to the application layer.
bootloader_uart.hexEventSystem.hex2210.s140_nrf52_7.2.0_softdevice.hex
Why is the application start address at 0x00001000?
Either you are using a settings page that have wrong start address, or you have configured the app start address wrong. Try erasing the whole chip and flashing again examples\dfu\secure_bootloader\pca10056_uart_debug on a clean chip. Flash all bootloader, application and valid settings page.
