Getting Started on nrfGo Studio programming nrf51822

[spms1027]

Hi,

So I'm fairly new to programming the nrf51822 and using the Nordic platform. I'm currently using the nrf51822 Waveshare DK. I have setup JLink5.1.2, nrf5_MDK_8_5_0, ARM Keil 5.20 lite and I've installed nrfGo Studio. When I load up nrfGo Studio and connect my board via USB no board is recognised and I the option for nrf51 is greyed out. I just need helping diagnosing why this is and getting to the point where I'm able to flash the SoftDevice and then flash my own applications. Below is a picture showing this problem.

I'm not sure where I'm going wrong or if you could help me. But if possible any suggestions would be more than welcome.

Thanks you for your time.

hello spms1027,

Do you use any kinds of the debugger like J-Link Lite ? If you only use the EVB like this, seems there's no debugger on the EVB. The USB on the board connects to the CP2102, which is a USB to UART bridge. This bridge only connects to the UART peripheral on nRF51, and basically you can not use nRFgo Studio to program the chip through it. nRFgo Studio needs a Segger J-Link to program the nRF5x.

Thanks for the help. I was wrongly using the BLE400 as if it was the nrf51-DK. I've ordered myself a J-link lite. Thank you for the assistance and apologies for my inexperience.

I have similiar problem. I installed Segger J-Link, but my board hasnt been recognized via usb (in control panel i had CP2102 with yellow "!"). So i downloaded drivers to it and now it appears each time i connect my board via USB. But still i can not program my board. nrfjprog in command line says there is no board connected. I can not find any boards via JLink GDBServer. How did you solve the problem to program nrf51822? I am not sure if my motherboard is malfunctioning. The led called SPD (lights up when i connect it for about 10 seconds and then lights down. Is it normal? Hope you can help me. Kalreg.
