You need to contact your TI sales rep or tech support to sign an NDA to get the HDMI documentation. Also, take note that your company should be listed in HDMI.org in order the TI releases the said document. regards, john On Mon, Nov 5, 2012 at 1:59 PM, Federico Fuga <ml@xxxxxxxxxxxxxx> wrote: > Hi Everybody, > > I am working on a custom OMAP4430 board with HDMI support.
