My device is NRF51822AC.I follow the operaion of the example showing,and set the "uicr_config.h" with const uint32_t UICR_ADDR_0x14 __attribute__((at(0x10001014))) __attribute__((used)) = 0x0003c000;,but the KEIL retruns Error: L6982E: AT section main.o(.ARM.__AT_0x10001014) with base 0x10001014 limit 0x10001018 overlaps address range with AT section bootloader_settings.o(.ARM.__AT_0x10001014) with base 0x10001014 limit 0x10001018. The examples are developed base NRF51422,when I change to 51822,always leading to something wrong.Drive me crazy.Coulde you sent me a S130 DFU example base on the chip of NRF51822AC?

Keil does not have any algorithm to write to the UICR registers and it can only be done using nrfjprog. Take a look at the UICR config example in the SDK on how to set it up.

Thank you,Sigurd. I know how to use the command.but the problem ofNo Algorithm found for: 10001014H - 10001017H is still eixstent.

The nrfjprog --help will list the different input parameters and other help documentation. You can write what you want to unused registers with nrfjprog --memwr Address --val value. Is this a nRF51 or nRF52 ?

I have removed the C:\Program Files\Nordic Semiconductor\nrf51\bin\ ,now the nrfjprog can run.But I don't know how to use the commands line to program the chip.Do I download the code via the J_Link ? Is there an example? I just want to program UICR register for next step debug.

Whats in the nrf51 folder? Try to remove it from the path variable, and see if its work.

I check the windows PATH, there are two paths.One is C:\Program Files\Nordic Semiconductor\nrf51\bin\,and the orther isC:\Program Files\Nordic Semiconductor\nrf5x\bin\, Why are there two PATH variable?Should I uninstall the NRFgo studio? I think they conflict.

Yes,the window closes .program exit quickly.

The window closes? If you dont use any commands, it will just list the commands and exit the program. But the window should not close.

I type nrfjprog in the run window ,the result is the same as double click.Is there any orther method?

If you just double-click on the nrfjprog.exe, it will print all usages as shown in your picture and then exit. You should instead open the run window(press Win+R on your keyboard to open it), then type cmd and press Enter. Type nrfjprog and press enter, the window will now not close.
