Hi,
I removed all but the linux-omap list for my question.
I am trying to get the beagleboardxm to work with an external codec. I
am trying to use a mcbsp1 via the trainer board where it level shifts to
5 volts. I have applied this patch (I am on 2.6.39rc4), but still no
joy. I have a small analyzer attached to the I/O pins and important
things like the bit clock does not wiggle.
First a side question. In the arch/arm/mach-omap2/Kconfig when I select
BEAGLE, it selects OMAP_PACKAGE_CBB - but my bbxm system reference
manual says "The BeagleBoard-xM processor is the DM3730CBP 1GHz version"
which to me implies the proper package selection should be
OMAP_PACKAGE_CBP. The platform file mux34xx.c has different tables for
them, but I cant quickly tell the difference. Does this matter for mcbspx?
Here is a console dump where I try to aplay a file:
