SoloX: Is there a way to output 32KHz reference ?

Hi,

I saw that SoloLite and DualLite can output a 32KHz reference clock  (from 32KHz XTAL).

Is there a way to do the same with Solox ?

Are the muxing "ANATOP_32K_OUT" or "OSC32K_32K_OUT"  are equivalent ?

I've tried them without success.

Is there a (undocumented) enable bit in CCM module for this output ?

What is the recommended Pad configuration (regvalue to set in DTS will be perfect).

Thanks,

Martin

Hi Martin

also one can try to output clock ckil_sync_clk_root

using CCM_CCOSR register. For dts example one can

look at CCM_CLKO1 in

linux-2.6-imx.git - Freescale i.MX Linux Tree

Best regards
