We have some NRF51-DK devices here. Recently we upgraded our segger software to v5.00. During programming using nrfjprog we got the question to upgrade the emulator firmware. We did this, and it works.
But we have a problem with the serial port. We can not get any inforamtion from the nrf51 uart to the pc and vice versa. when we downgrade the emulator firmware back to the original state it works again. But now we get the question to upgrade every time we program.
Any ideas how to fix this?
