CRC ERROR nrf5340

[emag nioj]

Hello, i have a custom board with lot of CRC ERRORS the same code, of course, works on the PDK. The spectrum transmission seems the same of the PDK.

Is it possible that the 32Mhz oscillator is the cause?

Is there a simple example to configure 125 Kbits  now i m using Nrf_1Mbit 

Is there a workaround reducing the speed or some other config parameter?  i need just to send few data

thank you!

The crystal you have is a 8 pF crystal (CL value). So the load caps should be 12 pF.

Ccap = CL * 2 -Cpin, where Cpin = 4 pF.

Given that it works with a generator, your crystal is probably not loaded correctly. This will pull the frequency and affect the radio.
