OMAP L138 McBsp0 and McAsp0 using the PSPDRIVERS

Hi, 

I am using the pspdrivers_01_30_00_08 examples, but I have a problem that I need an extra tip to solve it.

 

I use the Mcbsp0 and the Mcasp0 together, as indicated in the class driver that comes with the samples of the pspdriver. I have defined different DIO Adapters for the audio (Mcasp0) and for Mcbsp0 but the problem is that both interfaces work well only when I disable one (for example I define the DIO and the DEV for all devices, on the dsp/bios but I don’t create both SIO channels, only one (audio or the mcbsp)).

When the Mcbsp0 is working as expected the SIO information is device id =0x0 (HW_INT6).

But when I create all SIO channels, Mcbsp don’t work and the SIO information indicates that all devices have the same device id (0x0) and the HWI change to INT10, to all, but the audio interface still working ok.

I notice also that in this case the task that hold the issue/reclaim of the Mcbsp0 is always pending.

 

Can anyone help me please?

Regards
