Win7 master control panel crashes

[olovh]

Hi,

I downloaded and installed latest master control panel for Win7. It now crashes when communicating with nrf51 dongle. Seemed like it crashed the first time while it was automaticlly upgrading the firmware on nrf51. I get the same error, using same dongle, on two different 32-bit and 64-bit computers.

I also tried flashing firmware manually - but no difference. C:\Users\Root>nrfjprog --snr 480108701 --program "c:\Program Files (x86)\Nordic Semiconductor\Master Control Panel\3.7.1.8567\firmware\pca10000\MEFW_nRF51822_0. 10.0_firmware_1M.hex" Parsing hex file(s). Checking that there is no data to be written in region 0. Checking that there are no UICR conflicts. Disabling flash write and erase protection mechanism. Checking that the area to download is erased, and erasing if necessary. Erasing pages 0 to 44. Programming. Enabling flash write and erase protection mechanism. C:\Users\Root>

See crashdump below for version numbers. Any ideas how to preceed?

thanks, Olov

May I ask you to download nRFgo Studio if you haven't already and try to program the dongle with a code example from the SDK? For example the beacon example "ble_app_beacon". You need to program the softdevice as well. I ask you to do this just to make sure that the programming of the dongle is working as intended to rule that out as an error source.

I have a similar problem. I was never able to resolve it but I have a work around.

It seems to be a seggar driver issue of sorts. Two options Do not use version 10 firmware and stick to 9 or If you want to use version 10 firmware. Open Master control panel goto File , Options, Serial port, select Show all serial ports.

When you open MCP this time with your dongle installed you will find two options in the Master emulator drop down box. Pick the COM port with out the serial number.

I have two machine that MCP will only this way and one that works with out serial port changes.

Thanks for reaching out,

I think you are on to something here, but I am not fully there getting it working again ..

At least the PCA10000 seems to work since it works using the sniffer application and its firmware. Enabling all COM-ports in MCP gives the option to select the port without serial number. Problem is that it gives "no response from master emulator" on COM15. Selecting the COM15 with serial number cause the application to crash (as normal).

I currently have SEGGER driver 6.0.2601.5 for the virtual COM-port provided by Jlink 4.92. Tried downloading latest Jlink 4.94 but it did not provide a newer driver.

At this point, are you able to go to file -> flash programming and then program the MEFW-file into to device? The MEFW file contains all needed for operation, so the chip should be erased before this. Then after you have programmed the MEFW, are you still getting the "no response from master emulator"? Do you see multiple COM-ports in use still?

Solved now! Flashing with MCP didn't work - it crashed. I used nrfjprog to program the module. On my 64-bit machine version 9 now works after following Antonios tip and changing baud rate to 115200! :=) Kind of obvious once realized.. The 32-bit machine does not work not even if I follow Antonios tip but support for the 64-bit machine is enough for me. Thanks again!
