Raptor Lake Platforms

Note

13th Generation Intel® Core™ Processor, formally known as Raptor Lake family. [RPL]-S Refresh is also supported.

Supported Boards

SBL supports various platforms corresponding to Raptor Lake-S Processors.

Each Raptor Lake board is assigned with a unique platform ID.

Board	Platform ID	SPI Programmer	UART	PLAT
RPL-S DDR5 (UDIMM S14)	0x0019	J8G2	R6J1	rpls
RPL-S DDR5 (SODIMM S17)	0x0011	J1G2	R6J1	rpls

Debug UART

For Raptor Lake platforms, serial port connector location can be found from the above table for each supported target board.

Note

Configure host PuTTY or minicom to 115200bps, 8N1, no hardware flow control.

Building

To build SBL for any Raptor Lake platform:

python BuildLoader.py build <PLAT>

<PLAT> = rpls

The output images are generated under Outputs directory.

Stitching

1. Gather Raptor Lake IFWI firmware image

Users can either download the full IFWI image if the IFWI image release is available or read the existing IFWI image on the board using SPI programmer. This image contains additional firmware ingredients that are required boot on Raptor Lake.

Note

StitchLoader.py currently does not support stitching with boot guard feature enabled. To stitch with Boot Guard enabled, please use StitchIfwi.py.

2. Stitch SBL images into downloaded BIOS image:

   python Platform/RaptorlakeBoardPkg/Script/StitchLoader.py -i <BIOS_IMAGE_NAME> -s Outputs/<plat>/SlimBootloader.bin -o <SBL_IFWI_IMAGE_NAME>
   

where -i = Input file, -o = Output file, plat = rpls

For example, to stitch SBL IFWI image sbl_rpls_ifwi.bin from RPL-S downloaded firmware images:

python Platform/RaptorlakeBoardPkg/Script/StitchLoader.py -i xxxx.bin -s Outputs/rpls/SlimBootloader.bin -o sbl_rpls_ifwi.bin

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

Flashing

Flash the generated sbl_rpls_ifwi.bin to the target board using a DediProg SF100 or SF600 programmer.

Note

Refer the table above to identify the connector on the target board for SPI flash programmer. When using such device, please ensure: #. The alignment/polarity when connecting Dediprog to the board. #. The power to the board is turned off while the programmer is connected (even when not in use). #. The programmer is set to update the flash from offset 0x0.

Capsule image for Raptor Lake

SBL binary for capsule image could be extracted from SBL IFWI image generated in above steps.

Extract bios.bin from SBL IFWI image:

python BootloaderCorePkg/Tools/IfwiUtility.py extract -i sbl_rpls_ifwi.bin -p IFWI/BIOS -o bios.bin

Generate capsule update image FwuImage.bin:

python BootloaderCorePkg/Tools/GenCapsuleFirmware.py -p BIOS bios.bin -k <Keys> -o FwuImage.bin

Note

BootGuard would not work if directly using Outputs/<plat>/SlimBootloader.bin for capsule image.

For more details on generating capsule image, please refer Generating capsule.

Triggering Firmware Update

SBL for Raptor Lake 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 Firmware Update on how to trigger firmware update flow. Below is an example:

To trigger firmware update in SBL shell:

1. Copy FwuImage.bin into root directory on FAT partition of a USB key

2. Boot and press any key to enter SBL shell

3. Type command fwupdate from shell

   SBL will reset the platform and initiate firmware update flow. The platform will reset multiple times to complete the update process.

   A sample boot messages from console:

Booting Yocto Linux

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.

See Platform ID Detection using GPIOs for more details.

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

See Configuration Tools for more details.
