Good Day,
I am unable to connect my Rigado BMD-200 (NRF51822) to nRFgo studio using the J-Link EDU Mini. However, using the nRF connect application for Android I am able to see the RigCom BLE transmission. I have connected the SWDIO, SWKCLK, GND (pin 3 and 5) and Vtref. I have connected the Vtref to the same supply as the Vcc of the BMD-200. I have also tied all of the grounds of the chip (pin 1, 2, 3, 4, 7, 10, 19, 26) because I wasn't sure if that was necessary. To put you into context, I don't yet have the PCB and so I have connected electrical wires directly to the pads.
In the nRFgo, I try the refresh button, but it doesn't find the device.
I have tried using the J-Link Commander CMD prompt. The Vtref gives me the good voltage, but after I enter the processor (Cortex-M0) and the default frequency of (4000kHz) it shows the following
Is there anything obvious that I am doing wrong, and is it possible to program the chip without the evaluation board?
Here is the results from the nRFjprog.
