Nrf52833 power cycling reset fail

[sky12334]

Hi,

we have nrf52933 custom hardware.

we are flashing application through j-link.

but after every flashing , I need to hard reset the board in order to run the function. Is it any wrong in the software or hardware? I let the nReset pin floating.

Any suggestion on that? 

Thanks,

sky

Hello Rex,

After programming the device, the CPU is halted and needs to be either power cycled or reset.

You could reset it using the RESET pin if it were connected, but if you are using for example nrfjprog command line tool to program the device, adding --reset should also reset the device.

Best regards,
