Re: Reg: Intel Rangley Support in EDK

["Desimone, Nathaniel L" <nathaniel.l.desimone@intel.com>]

Hi Dhanasekar,

I don't know very much about coreboot or the coreboot UEFI payload, so I won't be able to help you much with that. From what you mention in your message it sounds like either the coreboot UEFI payload does not include the TerminalDxe driver, there is a configuration issue with it. MinPlatformPkg is a pure EDK2 only implementation that does not have any coreboot dependencies, but it does not support Rangley at the moment.

With regard to the setup menu graphical corruption, the setup menu uses the CP437 character set, since the setup menu is often displayed using VGA text mode, whereas most current terminal emulators assume UTF-8 encoding. To make it render properly, use PuTTY and in the connection configuration under Windows -> Translation change the remote character set to CP437.

I suspect there are kernel parameters you will need to pass to make Ubuntu use the serial port as the terminal, I suggest looking at Ubuntu documentation or message boards.

Thanks,

Nate

Hi Nate,

Thanks for the info. I will try this. 

My Rangley platform has no onboard or offboard vga support. Com Port / Serial console is used for display and communication. 
I am booting the platform by coreboot with UEFI payload. I am trying to install Ubuntu server OS. 

When I boot into Shell, I am not seeing actually shell (graphics are not good) and keystroke are working properly. 
When I boot into EDK Setup, I am not getting proper setup page (graphics are not good) and keystroke are not working. 

When I try to boot Ubuntu Server, I am getting below error,

"error: no suitable video mode found.
Booting in blind mode"

It seems I am missing some video/graphics settings in UEFI payload. If you know the fix, Please provide me. 

Thanks,
Dhanasekar

Hi Dhanasekar,

There is nothing pre-built and off-the-shelf ready today. But we do have a generalized infrastructure for open source Intel UEFI platforms called MinPlatformPkg. Please see the following:

https://github.com/tianocore/edk2-platforms/tree/devel-MinPlatform/Platform/Intel

Notice that MinPlatformPkg requires a *OpenBoardPkg that supports the desired platform. To my knowledge no one at Intel has looked at implementing a RangleyOpenBoardPkg thus far. The focus has been on recently released platforms, Rangley is 4 years old at this point. If you are so inclined, you are welcome to try implementing a RangleyOpenBoardPkg. I would recommend using KabylakeOpenBoardPkg as a starting point.

Thanks,
Nate

    Hi,

    I have booted Intel Rangley / MohonPeak platform in coreboot with Intel
    FSP.
    I am unable to install UEFI OS in coreboot (sometime).

    EDK bios will install both UEFI and Legacy OS.
    Does Open EDK supports Intel Rangley platform?.
    Is code base available for Intel Rangely platform?



    Thanks,
    Dhanasekar
