nrfjprog can't run

[Songplus]

Hi,I download the "nRF5x-Command-Line-Tools_9_0_0_Installer.exe" and install.my system is windows7_32bit.When double click to run the "nrfjprog.exe",the startup window exits quickly .I add the PATH "C:\Program Files\Nordic Semiconductor\nrf5x\bin" to the Windows PATH variable,doesn't take effect,and leading to "nRFgo Studio" can't run .I want to use "nrfjprog.exe" to solute the problem of debuging S130 DFU .Could you tell me how to solute the problem?

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

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.

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 ?

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

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.
