I'd recommend considering this for the SPI interface.

The PRU can probably bit-bang the SPI fast enough for your needs, and
you won't have any issues generating small 1-2 uS pauses. Basically,
just replace the SPI hardware with a PRU emulated version that supports
the timing constraints you require. Everything else sounds like it's
working OK.

Thanks,

I've considered the PRU's and abandoned them as they are too specific for the Sitara.
There is a project request to find a solution that is not locked to processor specific features.
Nor was a suggested Arduino slave approved.
But in time, I surely will test out these PRUs.
