DM8148 EVM board McASP "XCKFAIL" error?

Hi,

I am getting an "XCKFAIL" error once upon I enable the McASP 0 clock by using following: 

WR_MEM_32(CM_ALWON_L3_SLOW_CLKSTCTRL, 2);  /* 0x48181400 = 2*/

WR_MEM_32(CM_ALWON_MCASP_0_CLKCTRL, 2);  /* 0x48181540 = 2*/

The McASP transmit status XSTAT never has XDATA ready (=0)  status.

Can somebody tell me what else I should have configured to make the McASP clock working?

 

Thanks in advance.

Philip

    Hi Philip,

    It appears from the code that you are starting the clocks, do you have the McASP module itself enabled? Are there any pinmux items that could be affecting it? Do you have all the other transmit parameters configured?

    Regards,
