I am trying to package a firmware update and flash it over BLE DFU and I keep getting the following error on the nRF Toolbox app:
"Upload Failed: Unknown Command"
I cannot figure out why this is happening and I can't find anyone else having this error on here. Here are the commands I used to create the initial bootloader and settings (flashed over J-Link).
Generating the Settings hex:
nrfutil settings generate --family NRF52 --application ../AKDP/BUILD/AKDP_RevE.hex --application-version 20 --bootloader-version 1 --bl-settings-version 1 akdp_bl_settings.hex Generated Bootloader DFU settings .hex file and stored it in: akdp_bl_settings.hex Bootloader DFU Settings: * File: akdp_bl_settings.hex * Family: nRF52 * Start Address: 0x0007F000 * CRC: 0x9F32BF67 * Settings Version: 0x00000001 (1) * App Version: 0x00000014 (20) * Bootloader Version: 0x00000001 (1) * Bank Layout: 0x00000000 * Current Bank: 0x00000000 * Application Size: 0x0003EEB8 (257720 bytes) * Application CRC: 0xD62A0BD6 * Bank0 Bank Code: 0x00000001
Merging the settings hex with the bootloader hex:
mergehex -m akdp_bl_settings.hex ./bootloader_secure_ble/pca10040_debug/armgcc/_build/nrf52832_xxaa_s132.hex -o akdp_bl_with_settings.hex Parsing input hex files. Merging files. Storing merged file.
After flashing the softdevice and the bootloader, here is what I used to generate the package file:
nrfutil pkg generate --application ../AKDP/BUILD/AKDP_RevE.hex --application-version 21 --hw-version 52 --sd-req 0x9D,0xA5 AKDP_RevE_with_BL_pkg.zip
Other information:
- Device: nRF52832
- SDK: 14.2.0
- Board: Custom
I cannot understand why this isn't working. It all looks fine to me. The bootloader build completed without any problems. Any help would be greatly appreciated.
