Problem about Serial(UART) DFU

[sjheo]

Hi I'm Frank.

I'm testing Serial DFU via UART using TWO nRF52840 DKs(DFU master and DFU slave DK).

I want to update firmware of slave DK through the master DK.

I was downloaded DFU master code from here, and applied the example code to "SDK15.3.0\ examples\ ble_central\ ble_app_blinky_c" to update DFU slave DK.

The DFU protocol is written in the infocenter, but it doesn;t say exactly what data(data such as APP, SD, etc. that should actually be transmited via serial) should actually be transmitted.

So, may be stupid, I uploaded secure_bootloader\pca10056_uart_debug to the DFU Slave DK. And I uploaded blinky_mbr.zip provided in secure_dfu_test_images folder with nrfutil to check the log.

The result is as follows. After that DK LED is blink.

C:\Users\tktlz>nrfutil -vvvv dfu serial -pkg blinky_mbr.zip -p COM17 -b 115200

Now, after UART configuration of DFU master DK and slave DK, the same command and data streaming as nrftuil result log is transmitted from master DK to slave DK.

But there is a problem.

The results of testing with the UART, not the nrfutil command, are as follows.

The response is almost same, but the response to the last two commands, Caculate CRC(0x03) and Execute(0x04), is different from the nrfutil log.
The firmware to be updated is the same as blinky_mbr.zip.

 

I have a few questions about the above situation.
1. What does the data I send to the DFU slave DK after creating Object 1 (0x01 0x01 LEN) mean? I don't know the meaning of the data because I followed the nrfutil debug log.

2. What is the reason for the above 2) DFU slave UART log result? ( about the response to the CRC and EXECUTE commands.)

3. The whole test above simply update of the APPLICATION area. How do I update the SOFTDEVICE or BOOTLOADER through serial DFU?

Do you have any example or documentation?

I hope you can get some help. Thank you.

Hi Frank,

1. What does the data I send to the DFU slave DK after creating Object 1 (0x01 0x01 LEN) mean? I don't know the meaning of the data because I followed the nrfutil debug log.

Which line in which log do you refer to now? Generally, you can see the format of the commands here. Create object takes two parameters, object type and size.

2. What is the reason for the above 2) DFU slave UART log result? ( about the response to the CRC and EXECUTE commands.)

 It looks like the CRC is different. As you have the same .zip file you are testing with I wonder if you are seeing a common issue when doing serial DFU with the DKs, which is that the onboard debugger can corrupt the UART traffic (which passes through it). The workaround then is to disable the pass storage device on the onboard debugger. See Disabling the Mass Storage Device functionality (note that it does not matter if the doc is for Zephyr, this is a generic issue with the onboard debugger on the DK)

3. The whole test above simply update of the APPLICATION area. How do I update the SOFTDEVICE or BOOTLOADER through serial DFU?

The update procedure is exactly the same for SoftDevice or bootloader. This is encoded in the init packet that is sent to the bootloader at the beginning of the upgrade procedure, and the bootloader itself handles the relevant differences without the need for the DFU master to behave any differently for different types of updates.

The bootloader documentation is quite good, though it is a bit slim on the protocol.  You will get a good overview for serial DFU from this page.

Thanks for your comment, Einar.

The DFU test was delayed because I had to deal with other works first. Really sorry about late reply..


As you said, the reason why my DFU process fail is because CRC is different.
The data in the APPLICATION area was written incorrectly.. 

Now, I'm done serial(UART) DFU test and I integrated secure bootloader UART and BLE.
Both methods were tested.


But, only the DFU  for the application area was tested, and the DFU about softdevice or bootloader area seems to need a little more study. 

If I ask a related question later, please kindly answer again.
