using nRFgo with nRF51822

[Sperkmandl]

Hi, this is my very first post to this forum. I just received my nRF51 DK, so I installed a lot of stuff. The blinky example is running fine. A question about nRFgo Studio: in the Device Manager I see nRF5x disabled (grayed). How can I activate it ?

update: I reinstalled nRFgo Studio and I noticed the warning "jLinkARM.dll is not correctly installed. Please run the nRF Tools installer ..."

Thanks - Renzo

Hi,

How did you flash the blinky example ?

nRF5x Programming is grayed because you would need the external Jlink programmer for that. In your case you don't use that one. Use the one at the tab "nRF52 development boards" instead.

You may want to install nRFTools.

Hi, blinky was run just following the GettingStarted instructions, e.g. copying to drive Jlink. I installed multiple times nRFGo Studio, tools and Jlink. I noticed that:

• latest version from Jlink is 512
• nRFGo Studio wants Jlink 510d
• nRF tools want Jlink 510m

We end up with three installed versions of Jlink. Even installling Jlink first, the other two seem to ignore it and install their own version.

My likely mistake was not to reboot. Now I did it and - after a request to update the firmware and a nRFGo Studio crash - I got a new device named SEGGER 681669522 and a right panel named "nRF51 Development board - 68...". The device "nRF5x Programming" is still grayed, though. I don't know if this output is what I should expect. I will proceed further.

It looks good Sperkmandl. You can start flashing by click on the Segger 681 ... . As I said you don't use nRF5x Programming if you don't have external programmer.
