Yeah, the PRUs are there, but hidden I guess for "support" reasons. I think
TI isn't offering the firmware loads to support industrial protocols on
this chip to the public. TI already makes a carrier board SOM.  I want to
make sure those people who have invested in the BeagleBone form-factor get
pay-off with upgraded processing. I'm sure there is lots more that could be
done with the TDA4VM. I'm going to try to see if I can at least get a
fairly high-speed ribbon cable brought off, but things like PCIe will need
to be muxed across type-C in this form-factor as best I can tell.
