OMAP-L138 Line out problem

Rudolph Raab

Other Parts Discussed in Thread: OMAP-L138

I have several OMAP-L138 Boards (TMDSEXPL138-UNV) from LogicPD, and I can't get anything to come out of the line out port. I've tried both LogicPD's example code and some code from a textbook.

If it helps, I've attached the LogicPD example code that wont work. It hangs at line 199, the while loop condition is never satisfied.

Edit: Here's more information: the code in question is waiting for the register SRCTL11 of the McASP0DSP to have its XRDY flag (bit 4) set to 1. Inspecting the register in CCS shows that the while loop hangs with SRCTL11 having the value 0x000D, which indicates that the serializer is set to transmit, and the corresponding transmit buffer (XBUF11) is clear and ready to receive data. I can't figure out why the McASP isn't setting bit 4 on SRCTL11. Can anyone help me?

Hi team,

Is there an update available regarding this inquiry?

Hi Rudolph,

Can you try the attached main_audio.c and test_audio.c which is working fine for us on OMAP-L138.

From CCSv4-2-4_with_SOM-M1_BSL_WS\DSP eXp Audio Test

In main_audio.c – the code is

// uncomment this define if running without gel initialization.

//#define NO_GEL (1)

Change this code to

// uncomment this define if running without gel initialization.

#define NO_GEL (1)

Also, in the above code attached, in test_audio.c the testAudioLineIn() has been disabled for your clear understanding of the testAudioLineOut() code flow.

As last checkpoint, do check whether your headphones are working properly.

Thanks

Iyshwarya
