HDMI Initialisation??

Hi

Running 'bare metal' can anyone tell me the minimum subset IPU etc components that have to be initialised to display a frame store via hdmi.. The SDK goes part way there, but includes a whole host of stuff to initialise parallel connected panels too, and I fear I'm getting lost in the detail.

I think, in particular, where does the HDMI specifically get its data from .. is it a synchronous interface in DP.. if so which? .. OK.. answered that bit: found the IOMUXC_GPR3 bits that connect hdmi to one of the IPU channels.

Thanks in advance.. John

Hi

I'm running bare metal.. hence I'm responsible for BSP and board.. I am

happy about that, it is just that I am getting very confused about

exactly where control signals originate.. and especially which

'elements' are involved in setting the pixel clock given to the external

hdmi display.
