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 used the latest firmware available from the Nordic download section. Its filename was "J-link OB-SAM3U128-V2-NordicSemi 160212.bin". I debugged the communication with the logic analyzer. I found the traces for the usart and connected them to the analyzer. You could clearly see that the programmer was correctly sending data, but it kept the rts pin active so the nrf did not respond. I then tried an example application where i disabled the rts/cts flow control and it worked. So as a final hail marry i tried upgrading the firmware of the programmer and that seemed to fix it. I am not sure what was my previous version of the programmer software.

    Hope you get things working again. I spent nearly a day trying to fix this.
