The example bootloader accepts images that contain a new bootloader, SoftDevice, application, or any combination of these. To protect the target device against malicious attackers trying to impersonate the rightful sender of the firmware update, the init packet of the firmware package must be signed.
When performing a DFU, you must provide a package (in zip format) that contains the firmware image, an init packet, and a manifest file that indicates the package format. The init packet contains information about the firmware image that is used to validate the image, and it must be signed to ensure that the update stems from a trusted source.
To create a zip file that contains the firmware image (or images) and the corresponding init packet, use the nrfutil tool (version 2.2.0 or later). This tool is available as a standalone Python package from the Nordic Semiconductor nrfutil GitHub repository or can be installed from pypi with pip install nrfutil. See the nrfutil documentation for more information. Run nrfutil pkg generate --help to display help about creating a zip file.
You can also combine several images in one zip file. Note that, depending on the combination of images, the created zip file might contain two firmware packages (one for the bootloader and/or SoftDevice and one for the application) and the DFU process will be carried out in two steps. If you include both a bootloader and a SoftDevice in your firmware package, those two images will be merged together. An application, however, will always be updated separately after the other updates are completed.
Validation of the image includes checks to verify that the image originates from a trusted source and that it is compatible with the device and the current firmware and hardware. If the flag is_debug is set in the init packet, the debug version of the example skips version validation.
The open-source Simple Management Protocol (SMP) was originally created for flashing firmware on devices running Mynewt and Zephyr operating systems. SMP is based on the Bluetooth LE Generic Attribute (GATT) Profile.
PineTime stores two firmware images in Flash ROM: Active and Standby. PineTime boots from the Active Firmware Image. It activates the SMP service for firmware update over Bluetooth LE.
If the new firmware doesn't start properly, at the next reboot the bootloader swaps back the Active and Standby Firmware images. The bootloader starts the Active Firmware Image (now containing the old firmware)
Active Firmware Image: Contains PineTime firmware code that will be executed. The image starts with a Firmware Image Header (0x20 bytes) followed by the Arm Cortex-M4 Interrupt Vector Table (0xD8 bytes).
off: Offset of this chunk. Starts at 0. size: Total size of the firmware image data_len: Size of this chunk data_sha_len: Size of the SHA hash upgrade: If true, the version number of the new firmware must be greater than the Active Firmware version in Flash ROM
size: Total size of the firmware image write_bytes: Number of image bytes to write to flash for the chunk area_id: The flash area to write to proceed: Whether to process the request; false if offset is wrong. erase: Whether to erase the destination flash area.
To update PineTime's firmware over Bluetooth LE, the MCU Manager Library calls img_mgmt_impl_write_image_data to write each chunk of received firmware to PineTime's Flash ROM. PineTime Firmware Developers would have to implement img_mgmt_impl_write_image_data in C, so let's look inside the function...
MCUBoot (coded in C) plays a critical role in the firmware update process... During firmware update, MCUBoot swaps the old and new firmware images (and swaps them back if the new firmware fails to start)
arm-none-eabi-objcopy takes an ELF file compiled for Arm Cortex-M and copies the binary sections (code and data) to the BIN file. It strips away the ELF headers and other metadata that are not required at runtime.
Image Management: For querying and updating firmware images in PineTime's Flash ROM. This is the Command Handler that we have implemented to support firmware update on PineTime. See img_mgmt
Allow larger firmware images to be flashed: Based on the present Flash ROM Layout, the size of a firmware image may not exceed 232 KB. That's because we need to fit both Active and Standby Firmware Images into PineTime's 512 KB Flash ROM.
PineTime Firmware Developers would also need to enhance the Image Management Command Handler (MCU Manager Library) to write firmware images to External SPI Flash (instead of Internal Flash). (Possibly based on Mynewt's spiflash driver)
Coded in Go, Newt Manager is the official command-line tool for performing all MCU Manager functions on PineTime, including firmware flashing and date/time synchronisation. See newtmgr_image and newtmgr_datetime
If you are interested in upgrading the firmware on the RN-52s, you will need the USBD+, USBD-, GND and GPIO3 pins. The standard default v1.10 firmware on the RN-52s requires DFU over USB. After flashing the v1.16 (file rn52-i_rm116.dfu ), the RN-52 will have the ability to use DFU over UART.
7k.) Successful Upgrade Once finished, the utility will provide the total time it took to save your file and flash the new firmware. It took less than 5 minutes to upgrade the firmware:
When streaming music with the audio bluetooth and a call comes in, the smartphone will automatically stop the music and begin to ring until the call is answered/rejected. After answering or rejecting the call, the music will begin to stream again.
The first config (MCUMGR) will enable the mcumgr management library and the next two (MCUMGR_CMD_IMG_MGMT and MCU_MGR_CMD_OS_MGMT) enables the command handlers for image management and OS management. The image management command handlers makes it possible to upload, list, test and confirm the image(s), while the OS management command handlers makes it possible to reset the chip (and run the echo command). Since the DFU support is added to the application, the chip needs to be reset, to give control to MCUboot, which will validate the new uploaded image and swap it with the old image. Finally, BOOTLOADER_MCUBOOT includes MCUboot as a child image.
The nRF Connect Device Manager app will reset the chip after the transfer is completed. If the date and time output on the terminal is different from the one seen earlier, it means a different image is running and the update was successful
I have a similar problem. Basically downloaded the new updated bluetooth driver that popped up with my service tag. Hit install, halfway through install it popped into firmware upgrade DFU wizard unattended and hung there. Came back to find my Bluetooth Card Hosed (No longer enumerating in device manager). In my case it was a XPS 1640 Minicard 370, and the package was R205174 which says Vista on the dell site, but its the only one available, and the directory structure shows Win32/Win64 so it should be compatible. But then again, who knew they'd automatically jump into a firmware upgrade without any notification, I was expecting software drivers. Oh I've as of yet found no solution to this.
Sounds like you either have some drivers or firmware issue. Try to perform a manual firmware upgrade of the Bluetooth device. Run the following program: C:\dell\drivers\R226750\R226750\Win64\svcpack\SetupBluetoothDFU.exe. The program will prompt you for a ".dfu" file which is located in the same folder C:\dell\drivers\R226750\R226750\Win64\svcpack. After updating the firmware your Bluetooth should be working again. Of course you can also get the rivers on the Dell site. hope this helps, good luck.
"The DFU wizard did not detect a matching bluetooth device for the DFU image file you selected. please make sure you plug in the correct Bluetooth device and select correct DFU file then click next to continue." :( I don't understand how to activate bluetooth. . .
Has the bluetooth ever worked on your computer.? The Bluetooth is optional on your computer so make sure you have the Bluetooth option. If you do then you should have a Bluetooth indicator light above the F1 key. Fn+F2 that will switch your Bluetooth wireless on and off
No I never try to use it before. Yes there is a bluetooth indicator above the F1 key but it is not lightening on. Even Fn+F2 button is not working because F2 key has like battery sign instead of bluetooth.
I have had a sudden sudden bluetooth failure after using it earlier today. I spent 2 hours reviewing web comments on how to get it turned on and finally gave up and plugged in a bluetooth dongle which worked. I then shutdown and removed dongle and the internal bluetooth works again - I don't know why but I will accept result.
At the beginning of the upload process, the target might start erasingthe image slot, taking several dozen seconds for some targets. This mightcause an NMP timeout in the management protocol tool. Use the-t
SMP server supports downloading files from File System on device viamcumgr. This is useful with FS log backend, when files are stored innon-volatile memory. Build and flash both MCUboot and smp_svr applications andthen use mcumgr with download command, e.g.:
