Hi

I think I have seen this before when using custom board. I think that would be normal since nRFgo Studio can not detect type of a custom board. I see on your image that the HWID 0x3C which should be nRF51 QFAA Gx0 according to the nRF51 compatibility matrix. Do you have a custom board?

You should be able to program the chip with softdevice and application from nRFgo Studio even though the board type can not be detected. Are you able to program the chip from nRFgo Studio?

Hi Stefan,

We have made a custom board with connections only for SWDIO, SWCLK, VCC, GND and connection from PIN 21 to an LED. We use segger J-Link for programming. The IC is nrf51822 purchased from Tindie (link of product )

We are able to program it in Keil, but not in nRFGo studio (Screeshot show the nRFGo front panel when we connect the device)

Will nRFGo detect only the dev boards from Nordic?

What can I do to make my board programmable using nRFGo?

Hi

I am not sure actually why nRFgo Studio does not show anything in this case. You could try to use nrfjprog which is the command line tool that nRFgo Studio uses in the background. It should be located at \Program Files (x86)\Nordic Semiconductor\nrf5x\bin. Try to use see if it works after writing

nrfjprog --eraseall
nrfjprog --recover

You will also get some feedback on the command line when giving these commands, which perhaps could help you find out what is happening.

Make sure you use the latest version of nRFgo Studio.
