Hi thanks all for your help,<br>
<br>
I have arranged the "devicetree.cb" as suggested, you can see it at the attachment.<br>Put the superio chip under the LPC bridge section, but I didn't get how did you know it?<br><br>Added those to the romstage.c:<br>

> w83627hf_set_clksel_48(SERIAL_DEV);</div><br>main() looks like this now:<br>....... // omitted<br>sch_enable_lpc();<br>w83627hf_set_clksel_48(SERIAL_DEV); // NEWLY ADDED<br>w83627hf_enable_serial(SERIAL_DEV, CONFIG_TTYS0_BASE); // NEWLY ADDED<br>
uart_init(); // NEWLY ADDED<br>console_init();<br>printk(BIOS_DEBUG, "\n"); // NEWLY ADDED<br>....... // omitted<div class="im"><br>
<br>> The bit that controls the clock speed is in CR24.<br></div>But what about this, I don't know where CR24 is and how to set it? Sorry I am just really new in such stuff :s</blockquote><div><br>Found Winbond W83627HF/F/HG/G (id=0x52, rev=0x41) at 0x2e<br>

Sure you can find the output in the attachment.<br><br>By the way all I get is

Hi all,<br><br>I can't get serial output from the board I am trying to put coreboot on, so I am not able to go any further to see whats going on..<br></blockquote><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">
<br>The board has a Winbond W83627HF/F/HG/G (id=0x52, rev=0x41) at 0x2e.<br></blockquote></div><div><br>It is likely that you need to set the serial port's speed in romstage.c:<br>

#include "superio/winbond/w83627hf/early_serial.c"<br>
#define SERIAL_DEV PNP_DEV(0x2e, W83627HF_SP1)<br>
