nRF52832 UICR write through DFU

[Dinesh]

Hi,

Greetings!

We have successfully checked DFU application from SDK16.0.0 and it works nicely.

We have used android nRF connect app for firmware updating.

Here we have came across a issue and we wish to resolve it. Details are as below
1. We have kept 4 byte user information at 0x10001080 location, in UICR. (nRF52832)

2. When we update firmware through DFU this data do not get changed. Please note that these data is present in hex file.

3. Here we wish to know whether DFU supports UICR write feature?

4. If yes then how we can make it working and if no then how we can implement it?

Regards,

Dinesh

Hello,

Please check the answer I just gave in this ticket:

https://devzone.nordicsemi.com/f/nordic-q-a/62061/how-to-set-product-identifier-and-product-version-through-dfu

The answer is no. DFU doesn't touch the UICR. But for storing Firmware Version I don't recommend using UICR. Store it in the appliation itself, or in an FDS record.
