How to Test CLKIN1/B17 Pin on IMX93

[PBouchand]

Hello,

My company develops an electronic board where the CLKIN1/B17 pin of the IMX93 is exposed. Under Linux, what would be the simplest way to verify that this pin is properly connected?
I assume it’s not as straightforward as toggling the pin to 1 or 0, is it?

Thank you.

Hello and thanks for this information,

From what I understand, to use this as an alternative 24 MHz clock for the CCM or ANAMIX, the GPR20 register needs to be configured. For this to happen, the i.MX93 must be booted in secure mode.

Is that correct, or is there an easier way to check if it’s correctly wired?

Best regards,

Hello @PBouchand 

I hope you are doing very well.

The CLKIN1 and CLKIN2 are just for internal test propuse.

Best regards,
