I enable and build my kernel with driver (staticly): Multi-IO cards (parallel and serial) (in Device Drivers-> Parallel port support ) This is what my board say (in console mode) about serial address: 0x08 COM1 DUART8245 0xfc004500 0x07a12000 0x00000001 0x01effc70 0x09 COM2 DUART8245 0xfc004600 0x07a12000 0x00000001 0x01e107d0 > - are you sure that you enabled "console on serial port" in the config ? Yes, i enable " Support for console on virtual terminal" but i enable "Non-standard serial port support" option too... So i recompile without the last one... and i recompile "with Serial drivers --->" "[*] Console on 8250/16550 and compatible serial port" perhaps it's that... And i came back to you. But, perhaps i've allready tested... i ll check.. it's not a default option ? > - how can you be certain that the serial will appear on ttyS0 and not ttyS1 > or another one (the kernel might detect another serial port which it > assigns ttyS0) I pass parameter directly to the kernel; Another option i set : Default bootloader kernel arguments x x x x(console=ttyS0,9600 console=tty0 Thanks Yann. > - is it possible that you have trouble with the endianness of the image ? > example: little endian image loaded on big endian CPU ?
