how to write data to UICR？

[Carl Sun]

Hello,

In nRF52832 we use these commands to write data to user information configuration register:

nrfjprog -f nrf52 --memwr 0x10001080 --val 0x00010000

and use memcpy to get the data in C code.

My question is: how do we do it in nRF5340? what is the address we can use to write data? I checked the documents but there is no examples.

Thanks.

Carl

Hi, Einar.

In nRF5340 DK, I did this:

1. use nRF connect to "Erase all".

2. in power shell issued this two commands:

nrfjprog -f nrf52 --memwr 0x00FF8100 --val 0x00010000

nrfjprog -f nrf52 --memwr 0x00FF8000 --val 0x00010000

but I got error message, it seems I did write successfully.

What is the problem?

Thanks,

Carl.

Hi, Einar,

I changed the command to:

nrfjprog -f nrf53 --memwr 0x00FF8100 --val 0x00010000

It works. 

Thanks for your support.

Carl.
