OMAP-L138, MCBSP_DigLpbkExampleProject doesn't generate clock signals at MCBSP1

Hello, everybody!

I have a custom board with OMAP-L138. I want to use MCBSP interface and compilled MCBSP_DigLpbkExampleProject from pdk_OMAPL138_1_01_00_02.

But there are no any signals on MCBSP pins when I run it through JTAG. I'm using MCBSP #1.

What I only did?

1) I configured all pins MCBSP1 pins (removed pull-up/down built-in resistors, set pinmux(1) register to work as MCBSP)

2) in the project:

- McBSP internal clock to be used => Mcbsp_SrgClk_CLKCPU

- Mcbsp internal clock frequency => 150000000

- coreNum = 1 and CORE_SYS_INIT = 1 (to run at MCBSP1)

- all clocks set to => Mcbsp_FsClkMode_INTERNAL

3) after run I see:

[C674X_0] Debug(Core 1): Running MCBSP Digital Loopback example on the DEVICE
Debug(Core 1): MCBSP Driver Initialization Done
Debug(Core 1): EDMA Driver Initialization Done
Debug(Core 1): If required to restart set debugCommand variable to 1

Project is running well but doesn't enter in mcbspAppCallback() function.

Maybe I need to do something else? I want OMAPL138 generate CLK and FS (namely CLKX and FSX) signals.

My CPU frequency = 300MHz.

Best regards,

Bakir
