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.

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

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 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.

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.
