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

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.
