Master control panel windows 10

[Martin Tramšak]

Hello,

I've upgraded my machine to Windows 10. I can't get Master control panel to work. I keep getting the error message:

No response from master emulator

I installed all of the drivers properly. The COM port seems to be working properly since my applications work.

What I have tried:

• both pca10028 and pca10000 dongle
• both baud rates (115200, 1M)
• the last three versions of the master control panel
• Different firmware versions (10 and 11).
• tried pressing reset, unplugging the board...

Turns out it was a firmware problem on the programmer part of the boards. Not exactly sure how this happened, but the programmer (JLink) was asserting the RTS pin so the communication did not go through (NRF51422 was not responding).

I downloaded the latest firmware from the website, flashed it and voila. Everything works as expected.

OK, thanks for the details. I noticed that the latest version of Keil v5.18a forced the upgrade of all connected JLink devices to upgrade to v5.10l which broke my nRF51 Dongle from working with Master Control Panel. Using JLink Configurator v5.10d I was able to downgrade the firmware of my JLink devices to v5.10d including the nRF51 Dongle which got things working again.

This issue is unfortunate and it looks like newer versions of the Master Control Panel firmware may be tweaked to work with the latest versions of the JLink firmware from Segger. Fortunately, the fix of downgrading the firmware worked to get me going again, but after several hours of head scratching. I'll try the new firmware you linked to see if that works as well.

I thought I had bricked my nRF51 Dongle, but your posting put me on the track of checking the jLink firmware on the nRF51 Dongle. Thanks for the lead.
