If reworking the PCB is not feasible, you can test the board as is to check for stability and performance issues. undertale

Hello Rakesh,

What is the value of your load capacitors to ground from XL1 and XL2? Look at the connection at our reference design.

I have asked our expert. According to the datasheet (https://no.mouser.com/ProductDetail/ABRACON/ABS05-32.768kHz-7-T?qs=XAiT9M5g4x%252BdZqLQfRhFYw%3D%3D) CL = 7, so you can use 12pF as load capacitor.

Thanks.

Test the circuit to see if there is an error. I have the same question cookie clicker

Hello Rakesh,

Do you have Low frequency Crystal oscillator (LFXO) in your design?

Thanks.

Hi Kazi,

I have added 1 mfd capacitor to the DEC 4 now its getting programmed and working when in debug mode once the SWIO and SWDCLK removed and power recycled the device is not working any idea why its happening ?

Imp : R49 and R50 is Not populated

Thanks,

Rakesh

Hello,

You need to add 1uF capacitor for internal LDO setup at least.

The inductors to DCC is needed when you need DC DC regulator setup.

You can check the reference design here : ://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52832.ps.v1.1/ref_circuitry.html?cp=4_2_0_52#concept_aqp_fd1_fq

Thanks.
