Steve,
I'm disappointed in TI's position on this.
This page
<http://focus.ti.com/docs/prod/folders/print/tms320dm6446.html>
clearly shows SPI as one of the available peripherals, so to my way of
thinking TI should be providing an official Linux driver for it. Or at
least working towards providing an official SPI driver.
If EVMs for a particular processor do not expose all peripherals then
the EVMs need to be updated.
How does TI internally test that the SPI port works at all ?
Regards,
Andrew

We have been using a bit-banging SPI driver for several years to write
to some GPIO expander chips. I now need to read some inputs from the
GPIO expander. The driver is not working in read mode and I am
debugging it now. But, I was wondering if TI has gotten a TI 6446
hardware SPI driver working.
SPI for DM6446 is not officially supported by TI because there is no SPI
device on DM644x EVM. Therefore, can not be tested. I would expect the
DM6446 SPI to work with some driver modifications. Since you already
have the write working, you should be pretty close with read.
