McBSP2 registry dump file/function on OMAP4470

Srinath Danavulapati

Hi All-

I am trying to find the function/file on OMAP4470 (Blaze reference platform) that will give me a dump of McBSP2 registers. I found one function by grep'ing "omap_mcbsp_dump_reg() in file kernel\arch/arm/plat-omap/mcbsp.c file. This function is being called by omap_mcbsp_dai_hw_params() in file omap-mcbsp.c file. However it seems no one is calling this function and hence I don't registry dump.

Background:

We have connected a cellular modem on McBSP2 line to get the PCM auido data. When I make a voice call, I clearly see the audio path is enabled but the mic (transmit path of ABE) seems to be silenced/chirpy. So I am trying to dump the McBSP registers to see what the current values are.

Any help to locate the control path of code is highly appreciated.

Srinath,

Are you familiar with the omapconf tool for reading/writing OMAP registers? You can contact your TI representative for access to omapconf.

Gina

Gina,

Thanks for your response. I was able to solve my problem and did dump the mcbsp2 registers. The problem I had so far was, I was not in a voice call to activate mcBsp2 interface. Accidentally I just accepted incoming voice call and I started seeing all mcbsp2 debug on the console.
