unable to detect nrf52810 via nrf52 DK

[GHSN]

I have a module BL651 and I want to use it in my dev board. I've found in some previous posts that I have to use nrf52 DK to program externally the nrf52810 in my module.

Using the nrf connect, I can't detect the nrf52810.

The connection was made this way:

Without connecting the VTG, I can access to the nrf52832 in the nrf52 DK. 

With VTG, I got this error :

"Could not fetch memory size of target devkit: Error: Error occured when get library info. Errorcode: CouldNotOpenDevice (0x4) Lowlevel error: JLINKARM_DLL_ERROR (ffffff9a)"

So what is the problem here? Is it the connection or something that I've mised?

I think I get it.

It was the nReset pin: it should be in high position. The system held in reset state until this pin change to high.

It resolved my problem.

Thank you for your help.
