thanks for your reply,

I changed the configuration based on nordic documents and st link configurations but it still not worked in the nrf52xx series, it can't connect to the programmer, but I test more time if there is more problem I will report it here.

All examples in our SDK are configured to flash using J-Link programmers, as this is the only thing we officially support. If you want to use another programmer, you need to change the project configurations yourself to work with the programmer, or use a 3rd party tool (programmer manufacturer software, OpenOCD, etc.).

Thanks for your answer but I tried with 3 models on ST-Link and no one can connect to even the programmer with SWD interface, examples projects just can identify Segger J-link.

nRF52811 can be programmed by any device which supports SWD interface. However, we only provide support for Segger J-Link, as this is the only officially supported solution.

All our DKs comes with a built-in J-Link OB debugger, that you can use for programming external boards containing nRF5x ICs.

I am using the same board and I have this trouble too, after searches I found out NRF52811 only can program with jlink programmer and other solutions like https://devzone.nordicsemi.com/nordic/nordic-blog/b/blog/posts/programming-nrf51-with-st-link-uvision is related to the nrf51 series not for the nrf52 series.

This page describe how to flash the softdevice using Keil. If you have Keil setup to flash the board using the ST-Link device, it should also work for the softdevice.

I am refereed this blog devzone.nordicsemi.com/.../ and successfully uploaded but I think that cjmcu board is not come with the softDevice version so can you suggest me any method to upload the Softdevice using Uvision software or any other. I purposely not choose J-link because in my country it is very expensive and it shipping time goes to 40 days so I choose st-link v2 STM8/SMT32 mini

What exact type of ST-link V2 do you use, and what software? How is the programmer connected to the board? Have you searched DevZone for other threads discussing how to program the board using ST-Link? Note that we only officially support Segger J-Link programmers.
