How your reset vector will be called?

1 Answer

Answer from panel is bootrom code. I accept this I don’t know but he was asking what and all will be taken care by boot rom. We will not be having access to this bootrom code as it is vendor specific. He is asking the internals of bootrom code. He might be prepared for that and gathered some information to show that as a tough question. One more important point understood from this particular discussion is Panel doesn’t know Startupcode significance. There were listening to my explaination as if they are new.

He asked me about FTL.
