How to change default clock frequency in A10 fpga dev kit

Hi,

I am using A10 FPGA dev kit, by default clock generator IC - U14 SI5338 generates clock[3..0] = 302.083333MHz, 625MHz, 625MHz, 100Mhz.

I would like to change clock output 1 from 625MHz to 125Mhz as reference clock for xcvr in FMCA.

I just used BTS tool to change it to 125Mhz, but the configuration lost when power-down. It still keeps 625Mhz after re-start.

Is it possible to change it to 125Mhz without the reconfiguration every power-on.

Thanks!
