What has serial_getc() to do with that? Are you just mis-using this function for your purpooses? Why do you use such a dirty hack instead of simply using one of the clean ways to do this (like implementing a custom command and calling this preboot command.
Yeah, I'm just mis-using it. I basically just want to know why writing something through PCI won't show up properly. I'll convert this into some commands if there really is need for me to do it.
You're just adding complexity where it is not necessary. Keep things simple.
Yes. I know all the right infrastructure is in place, thanks for the great modularity..
Then USE it.
Yes, I get your point. Actually, thanks for being so bullish about it, I'll now just clean up the code and put in some commands there :-)
Fine :-)
Uh, actually, I tried both the approaches. Autoboot with 'go 0x40004'.
Remember that "go" expects a standalone application or something that will take over control completely.
