Sounds SW related, the CPU hard faults when you turn on the buzzer. Can you post the code?

I'm keep triying to work but I dont have result.
With only the VCC and ground connected works like a charm !! But it not a hardware problem 100% certified because in the last SDK was working without problems.
Also, reading the documentation i added before try to turn on the buzzer the method:
nrf_pwr_mgmt_feed();
but the same, the pcb reboots when the buzzer will turn on.

another test, If It be with the jlink wires and I turn on the buzzer, and then
remove the wires, the buzzer keep on, and I keep the connection alive and can turn off again.
What can be it ?? thanks !!
RE: Custom board reboot at high cosumption

navarrocantero — Thu, 13 Sep 2018 17:31:34 GMT
Yes sure!!

I have a custom with nrf58232 with a pair of leds in two pines separated respectively.
In a another pin i have a buzzer.
Here are the jlink wires, and the way of program it.
The custom board works perfectly in my old sdk (13) and I can toogle the buzzer without problems.
Now Im making the project again in the new sdk (15.2) and the first thing that I'm doing its toogle the buzzer with the methods bsp_board_leds_on() and bsp_board_leds_off()( I also test the method for single pines bsp_boards_led_on(PIN_NUMBER) ) in the nus_data_handler() method.
And the problem is that, when I connect the JLINK wires the PCB works perfectly, can toogle all components inside the nus_data_handler but without wires I can't work in the method, when I try to turn on the buzzer the pcb reboot, however before the main loop, I can toogle it.
Can be because have a high compsuption with the buzzer and the BLE connection togheter ? but in the older SDK was working
