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.

I've run into the same issues with my nRF51 Dongles no longer functioning after upgrading my Windows 10 system to Keil v5.18a which also seemed to upgrade some portion of my Segger JLink installation. When I plugged in my nRF51 Dongles, the Master Control Emulator software updated the JLink firmware and I now get following error in Master Control Panel:

No response from master emulator

How did you diagnose the issue with JLink programmer asserting the RTS pin so that communication didn't go through? Also, what specific firmware from what specific website did you flash?

I was able to get the things going again by downgrading the JLink firmware in my nRF51 Dongle down to 4.98c but this isn't optimal as the Master Control Panel keeps wanting to upgrade the JLink firmware now to the latest. I would like to really understand what JLink versions work with which MCE version.
