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.
