nRFGo issues with nRF52840(Rigado BMD340) Eval Kit

[Larry Affelt]

I have a BMD-340 eval kit (uses nRF52840) as does my contracted developer who has sent me a hex file to program into my board. I have installed The Segger Embedded Studio, JLink Software & Documentation Pack, nRF Connect for Desktop, the nRFGo Studio, and the nRF Commend line tools. When I run nRFGo I first get an error message about not finding 'ordinal 2578 in LIBEAY32.dll', then after clicking [Ok] and nRFGo runs it does not see my eval board (Segger 682506680) and I have an error message in the bottom window of nRFGo stating that nrfjprog.dll was not found even though it is installed and I found it on my drive. I am running Win7Pro 64 if that makes any difference.

Thanks to anyone who can help!

nRFGo is quite old now.  The recommended methods to program a target are to use nrfjprog on the command line or to use Programmer App within nRF Connect for Desktop.

Have you tried accessing the DK with either of these tools?

Hi Larry, 

as WestCoastDaz points out nRFGo Studio is quite old and in fact deprecated for the nRF52 Series. As Darren suggest, use the nRF Connect Programmer App in nRF Connect for Desktop or use nrfjprog from the nRF Command Line Tools. 

Best regards

Bjørn

Thanks for the feedback gents! I have been following the instructions given to me by my external contractual developer. I will try those tools today ...
