Crystall oscillator doesn't ouptut wave signal

[ssdgf]

Hi,

        The crystal oscillator on my custom board that connected with ECO_IN and ECO_OUT pins of cyt4bf8m doesn't output any wave signal. The eco_status register presents the eco is ok and ready, pll is locked also, but i can not probe any wave via chipscope.  And when i enabled the wco, it stuck at waiting for WCO_OK.

      The start up code is copied from sdl v7.5.0.

    So did i missed something?

Thanks!

Hello @ssdgf ,

For ECO related settings, I would suggest you the refer the "section  3.1 - Setting the ECO" of the App Note : "Clock configuration setup in TRAVEO™ T2G family CYT4B series (AN224434)". Also Please verify ECO TRIM settings.

For ECO Trim settings, You can also refer "section 18.2.2" of

"002-24401_0F_TRAVEO_T2G_Automotive_Body_Controller_High_Family_Architecture_TRM".
