Hi Zaid
How are you doing ?
I chhecked your post about your project and I have some details to clear
1- the ichip company , normally they NDA to be signed to release all material information and reference design , their price for license cold bro from 5k to 15kusd to all necessaries information to start doing your OWN product.
2- the Ti processor is just Soc.
3- your project need PCB design and firmware development, but from my experience ichip is best choice , as it dedicated wrapper so you don't need to involve much firmware work.
for PCB design this kind of PCB is High speed design board which require signal integrity verification and cross-talk verification as well including EMC too, and choose the right Power management IC to meet power sequence, my advise is to stick with this company called ichip and try to manage agreement with them to get more information's
if you need more assistance you're welcome you can PM me to discuss more.
