TCXO activation for timers

[jp52800]

Hi,

I am using a NRF9160. I would like to use nrfx_timer with a base frequency of 32MHz with the TXCO as clock source.

I saw in the documentation that timers use the base frequency of 16MHz with the XTAL as clock source.

How can I make this change?

Hi,

Thanks for all this information.

The modem version used is 1.3.6. I think it's the latest version.

Kind regards,

Hi,

 

Could you share information related to the assertion information that you are seeing?

Possibly a modem trace of this?

 

Kind regards,

Håkon

Hi,

Sorry for the delay. How do you enable modem traces?

I just saw that a new modem version has been released: 1.3.7. In the published note, it is indicated that a correction has been made for the pps: "Addressed modem instability when GNSS 1PPS functionality was turned on/off repeatedly." Maybe that was the problem?

Kind regards,

Hi,

 

Yes, please test with mfw v1.3.7.

Here's a way to enable traces, in case you need to do this in the future:

This is the known issue that was closest to your problem description, but to verify I would need the crash addr or a modem trace.

If this issue is easy to reproduce on your end, I suggest testing with mfw v1.3.7 to verify if it is indeed this very problem that you are running into.

 

Kind regards,
