Hi,

Have you checked the crystal load capacitance in the crystal datasheet and made sure the values of the crystal capacitors are tune correctly?

Have you measured the voltage on VDD?

Could you share the customers' schematics for review?

Best regards,

Marjeris

Hi Marjeris.

Thanks for your feedback, we use the customer PCB, and download the hello_world.hex, which follows the nordic SDK programmer process, but inspects the 32M crystal not working and UART1 did not print "Hello World", does that normal? , the hex is working well in the nRD5340DK.

Hi,

Are you using the nRF5340 DK or is this a custom PCB? Why do you think the crystal is not working? Are you following any of our tutorials for working with nRF5340?

Best regards,

Marjeris
