nrfgo restarts nrf51-dk or crashes

[Pascal]

Hi, few days ago when I attach the nRf51-DK and try to read the content, the nrfgo software freezes or crashes.

If it freezes i can see clearly the content stack of the nrf51-DK but after 1 sec, it disconnects and reconnects.

If it crashes, windows shows me just an error window.

If i connect an external device through the JLINK port, it works sometimes, sometimes not.

Anyway i can upload my code but obviously i cannot change the softdevice

Instead of using nRFgo studio, it is possible to use the nrfjprog tool from cmd to program the chip, could you try that and check if it works? Nrfjprog should have been installed with nRFgo Studio, however, if it is not, you can download it from the nRF51822 webpage --> downloads --> software --> nRF5x-Command-Line-Tools-xxx
