Hi,

I would recommend buying an nRF52 development kit, and use the on-board Segger J-link programmer on the DK. You can use the on-board J-link programmer to program both the on-board nRF chip, and also external nRF chips using the P19 or the P20 connector. See this infocenter page for more information.

in my case, i just can have this nrfboard link text and jlink clone 12$ form china :(. could you have other ways ?

You could try to recover it directly using nrfjprog. Open the command line, and use nrfjprog -f nrf52 --recover

Do you really need to recover your chip, or you are trying that option because you cannot flash? I used that cheap v8 clone some time ago with nRF51 - i just connected SWD lines, GND, and power detection and it just simply worked. However, I have not updated the firmware of the flasher, as it would become not usable.

i used jlink v8 cheap clone with nrf51, it worked fine. but when i connect to nrf52 and can't detect the chip. i think with nrf52, we have to use jlink portable.
