[U-Boot-Users] printf question - board at91rm9200

[CG]

Hello,

I think that's not really important for you, but I really don't know where
printf() function is declared in u-boot 1.0.0?

I see everywhere that printf is called in many and many functions, but I
really don't know how the string is sent through the debug serial port?

Anybody can tell how does it work?

The same question for input function like getc...

Regards
