how to generate 125M clock output?

[jiangyaqiang]

HI :

     how to generate 125M clock output?  I have try to CLKO2 and GPIO16(NET_REF_CLK), but fail, here is the result:

for CLKO2:

select gpio03 to clko2, but, only 24M clock output.

select NAND_CS2_B to clko2 and  root clock select 125M_CLK_ROOT (set CCM_CCOSR to 0x010900DB) , the clock output is about 262M.

for GPIO16:

clock output is 50M

Could anyone tell me how to generate 125M clock ? Thanks very much.
