SeaBios serial(RX) is not running.

[김유석 책임연구원]

Dear Sir.

Thank's your advise. everytime.

*Finially*, I was succsss the boot using coreboot.

But I have a *little problem.*

_*I'm can't typing throuth the serial.*_

My x86 BOX is only support serial console.

So, Serial console is very important.

*But **t**he **Sea**Bios is **Serial RX is fail*. I guess.

Coreboot => TX OK

SeaBios => TX OK. *RX Fail*

GRUB2 => TX OK, RX OK.

Linux(ubuntu 15.04) => TX OK, RX OK.

*TX OK* => Can see the log message throught the serial console.

*RX F**ail* => Can not typing throught the serial console.

I'm try to change the bootloader SeaBios to U-boot. and *U-boot is a TX, 
RX OK.*

Serial RX fail is a just SeaBios problem(Not HW issue). I guess.(Vendor 
builded coreboot(SeaBios) is TX/RX OK)

Please advise to me.

Thank you.

Hi,
  If you want bi-directional serial port in SeaBIOS, I think you need
to stick with the version from Sage. As far as I know, it's never been
supported in the upstream SeaBIOS version.

You might want to bring this up on the SeaBIOS mailing list.
