No response from nRF52820 when DFU is attempted again

[Louis_263]

Hello everyone,

I have successfully managed to perform a DFU with a DFU package consisting of an app and a softdevice. I wanted to test what happens when I manually cancel the DFU and then try to start a new DFU.
After I cancelled the DFU of the app and restarted the DFU, the DFU works without any problems and the app starts as expected.
However, after I cancel the DFU of the softdevice and restart the DFU, there is no response from the nRF in the DFU after a certain point.

This is the log where the DFU of SD + App worked:

log_ok.txt

This is the log where the DFU of SD + App did not work (after I cancelled the DFU of the softdevice manually):

log_fail.txt

In the log where the DFu didn't work, I see that flash memory is written to from address 0x27000. However, this is the area of the application. I would have expected that first in the area of the softdevices is written, because this was also so in the log where the DFU has worked.
Is this possibly a bug?

Best Regards

Louis

the softdevice+application DFU worked with nrfutil version 6.1.7.

It also works for me if I don't cancel the DFU manually. For me, it's about simulating an error case where the DFU terminates for some reason in the later product and you have to restart the DFU via remote. If I abort the DFU while the softdevice is being updated, and restart the DFU afterwards, then it won't work anymore. I also use nrfutil version 6.1.7.

Maybe you could test if it works for you. So during the first part of the DFU (Softdevice DFU) disconnect the nRF from power and then restart the DFU again.

i checked when device mode on dfu then i power off and then again connect it is show me on dfu mode

but i used nrf52832 module

My device is also in DFU mode but when I restart the DFU, then after a certain point no response comes from the nrf52820. Have you ever tested a SD+App DFU? As I described it in the original post

As I said, the DFU itself works. But when I cancel it manually and restart it, it no longer works. At the beginning, data is also transferred, but at some point there is no longer a response from the nRF. As can be seen in the logs in the original post, I think the bytes from the softdevices are also written to the wrong place in the flash memory (0x27000, but this is the beginning of my application). Normally the bytes should be written from address 0x1000. For these reasons, I think this may be a bug.

This is the log of the DFU, after I cancelled the the previous DFU manually while the softdevice is being updated:

Vidar Berg  Can you help out, maybe?

Louis_263 , this is a known limitation, unfortunately. From the SDK release notes:

** DFU **

- NRFFOETT-2579: If the transfer is aborted when transferring a SoftDevice to a device
  with no SoftDevice present (using sd-req = 0), the device can erroneously think that the SoftDevice
  was transferred correctly. On smaller devices there could be no room
  to transfer the SoftDevice again.
  Workaround: Transfer any application with sd-req set to 0.
  The application must be at least 3 pages (0x3000 bytes) long.
  The application will overwrite the SoftDevice, allowing it to be retransferred.

In other words, to allow the SD update to be attempted again, you have to prepare a dummy app update which can overwrite the Softdevice first.
