I don't think that is the situation that Shawn is describing. To me it sounded like he is starting firmware development before all of the functionality is delivered by the hardware engineers. I don't think
You are right. Then Ladislav Michl suggested to use special console functions for output, which works, but misses most of the "interesting" startup messages which are printed long before the device funtions are installed.
Ahh, thank you. I had misunderstood what you were talking about.
that he is refering to initialization order. Shawn, could you please clarify?
Initialization order plays only a role here as a console device starts working too late. The native console port is the serial port.
So what needs to be modified to do this? Create new serial_putc, _getc, _init etc. functions that send messages to where he needs them?
Cheers, g.
