Getting output from serial..... kinda....

[David Houston]

Hi all,

Would anyone have any suggestions why all I get out of my serial port when
booting my coreboot build is

��FƢ����=U$'E&&M#My=�F⌋!y=�FƋ!y=[$M#MO"My=+_Y�b��������������#⣉/y=+OIfyy=[$KKOK!K$L���H#C1�"b�㢢�VMK$LcDbD�b�#㢉

I know the usb converter is good as I have tested it on another machine. And
I know the serial port is good as I have got a linux terminal up with the
OEM Bios.

I'm not sure what else to attach to help diagnose the issue.

Hi,

Please answer following:

1) do you port new motherboard ?

2) if you  set speed to 115200 do you see something if you set on the other side 
57600 or 28200 bauds?

3) if you set coreboot to 57600 and the other side to 115200 do you get something?

4) Sometimes when the clock is nearly 115200 but a bit off some USB serials 
cannot handle that. Maybe you can try to connect some other device, or try to 
test with some real serial line on some other PC.

I am.

Both set to 115200, works fine with OEM BIOS to get linux console up.

3) if you set coreboot to 57600 and the other side to 115200 do you get

Same

4) Sometimes when the clock is nearly 115200 but a bit off some USB serials

Works on another PC.

If it is any help, minicom flicks between online and offline when doing it.

Good. what superio is it? Some have a bit to trigger if clock source is 24MHz or 
48MHz. Try to fidling with that.

We are on IRC irc.freenode.net #coreboot

I have attached my devicetree.cb & Options.lb where would I tweak the
clock source?

Thanks again

Hi,

That dump is from orig BIOS? If yes ~0x40 line may work ;)

Ok try this somewhere in the begining before enable serial (stolen from a8v-e_se)

#define SERIAL_DEV PNP_DEV(0x2e, W83627EHG_SP1)

pnp_enter_ext_func_mode(SERIAL_DEV);
         /* We have 24MHz input. */
         reg = pnp_read_config(SERIAL_DEV, 0x24);
         pnp_write_config(SERIAL_DEV, 0x24, (reg & ~0x40));
or
        pnp_write_config(SERIAL_DEV, 0x24, (reg | 0x40));

pnp_exit_ext_func_mode(SERIAL_DEV);
