Xtreme keygen

Note

8th and 9th Generation Intel® Core ^TM Processor Families formally known as Whiskey Lake and Coffee Lake Refresh platform.

Supported Boards¶

SBL supports Whiskey Lake, Coffee Lake Refresh Desktop S8+2, Coffee Lake Refresh Mobile H6+2 CRB platforms and UP Xtreme platform.

Building¶

To build SBL for Whiskey Lake, Coffee Lake Refresh and UP Xtreme platforms:

The output images are generated under directory.

Stitching¶

1. Gather Whiskey Lake, Coffee Lake Refresh or UP Xtreme IFWI firmware image

Users can either download the full IFWI image if the IFWI image release is available, or read the exising IFWI image on the board using SPI programmer. This image contains additional firmware ingredients that are required to boot on Whiskey Lake, Coffee Lake Refresh or UP Xtreme.

1. Stitch SBL images into downloaded IFWI image:

   For Whiskey Lake and Coffee Lake Refresh CRB boards: python Platform/CoffeelakeBoardPkg/Script/StitchLoader.py -i <BIOS_IMAGE_NAME> -s Outputs/cfl/SlimBootloader.bin -o <SBL_IFWI_IMAGE_NAME> For UP Xtreme board: python Platform/CoffeelakeBoardPkg/Script/StitchLoader.py -i <BIOS_IMAGE_NAME> -s Outputs/cfl/SlimBootloader.bin -o <SBL_IFWI_IMAGE_NAME> -p 0xAA00??10 '??' can be the following values: 02: Use PCH UART2 (Label CN16 on board) as debug serial port FF: Use SIO UART1 (Label COM1 on board) as debug serial port FE: Use SIO UART2 (Label COM2 on board) as debug serial port where -i = Input file, -o = Output file.

For example, stitching SBL IFWI image from Coffee Lake Refresh firmware image:

For more details on stitch tool, see Stitch Tool on how to stitch the IFWI image with SBL.

Flashing¶

Flash the generated IFWI image to the target board using DediProg SF100 or SF600 programmer.

SPI Header to connect dediprog is provided in the table below:

Board	Connector
Whiskey Lake	J3H1
Coffee Lake Refresh Desktop S8+2	J7H1
Coffee Lake Refresh Mobile H6+2	J7H2
UP Xtreme	CN18

Slimbootloader binary for capsule¶

Creating slimbootloader binary for capsule image requires the following steps:

Build SBL for Whiskey Lake, Coffee Lake Refresh or UP Xtreme:

slimbootloader binary generated in can be used for generating capsule image.

Triggering Firmware Update¶

Sample implementation of trigerring firmware update is explained below

SBL for Whiskey Lake, Coffee Lake Refresh uses BIT16 of PMC I/O register (Over-Clocking WDT Control (OC_WDT_CTL) - Offset 54h) to trigger firmware update. When BIT16 is set, SBL will set the boot mode to FLASH_UPDATE.

please refer to IsFirmwareUpdate() function called in to understand how SBL will detect firmware update mode.

Debug UART¶

Serial port connector on board is provided in the table below:

Board	Connector
Whiskey Lake	J8J1
Coffee Lake Refresh Desktop S8+2	J9B7
Coffee Lake Refresh Mobile H6+2	J4A1
UP Xtreme	CN16/COM1/COM2

Booting Yocto Linux from USB¶

You may need to change boot options to boot from USB. See Change Boot Options.

1. Download Yocto Linux
2. Create bootable USB key. For example: In Windows, Rufus can be used. In Linux, etcher app can be used.
3. Boot the bootable OS image from USB key on the board.

Board ID Assignments¶

Each board is assigned a unique platform ID

Board	Platform ID
Whiskey Lake	0x14
Coffee Lake Refresh Desktop S8+2	0x1B
Coffee Lake Refresh Mobile H6+2	0x16
UP Xtreme	0x10

See Platform ID Detection using GPIOs for more details.

To customize board configurations in file, make sure to specify to the corresponding values for the board.

See Configuration Tools for more details.
