For VGA support enable: CONFIG_VT CONFIG_VT_CONSOLE Then try with (I'm not an expert for x86) CONFIG_FB_VGA16 CONFIG_FB_VESA CONFIG_VGA_CONSOLE For the serial console: CONFIG_SERIAL_8250 CONFIG_SERIAL_8250_CONSOLE CONFIG_SERIAL_8250_PNP > If I use "console = ttyS0,115200" I don't see any output on my target's > serial interface (I've used minicom to check) Are you using a correct cable (host-to-host)? And don't use spaces in this parameter. It must be "console=ttyS0,115200" to keep it as one parameter. > Can I find a step-by-step guide somewhere? For x86 the net should be full of guides.

Maybe it already boots, but you just don't catch its output. Try harder ;) > I may be missing something obvious but don't know where to look next. Hard to say from here. I haven't an x86 at hand, so I can't do a quick test. Regards, Juergen -- Pengutronix e.K. | Juergen Borleis | Linux Solutions for Science and Industry | http://www.pengutronix.de/ |
