LimeSDR-Mini v2.4 - external clock

I have version v2.4 but on the page is only version v2.2

I want to use an external clock with LimeSDR Mini

On the website it is written “(remove R63 and solder R66)”, but on my version 2.4 there is IC20 in place of R63 and R66.
So the question is, how can you use an external clock in version 2.4?

Hi,

on LimeSDR-Mini v2.4 board version external clock source can be selected trough onboard switch (IC20).
To control onboard switch modify FPGA register:
Address - 0x00CF[0]
0 - VCTCXO (default),
1 - REFCLK IN J8

@ricardas can this be achieved via LMS API during setup? Seems like the sort of thing which should be, instead of having to directly modify FPGA registers.

Great, thank you for the information.

The question is: can this be controlled in a simpler way?
Or where can I find instructions on how to edit such a registry and then restore it to default settings?

Or is it possible to control it from the “device_args” level as in the example below from your website.
