1. I use custom board for nRF52832
2. I connected it with JLink, and installed SD132 with nRFgo Studio (successfully)
3. after then, I cannot connect to chip

I attach the log file of result of "nrfjprog -e --log"

The log you provided says "Device "NRF51822_XXAA" selected", but you say you have a nRF52832 chip on your board. Are you programming it using the correct family parameter? nrfjprog --family nrf52 --eraseall

Is there any possibility to use better JLink to nRF52? I have JLink which works well on nRF51, and used it to nRF52

[Jørgen Holmefjord]

You should be able to program nRF52 board using the same J-Link as you program nRF51 board with? How have you connected the debugger to the chip? This issue usually is due to a faulty connection, wrong voltage, some mistake on the custom board etc. Could you re-check that everything is connected and powered correctly?
