UP² 6000 Board

The UP Squared 6000 board (UP² 6000) is an x86 maker board based on Intel platform Elkhartlake. The UP boards are used in IoT, industrial automation, digital signage areas, etc.

Prerequisites

SBL supports UP² 6000 maker board. To start developing SBL, the following equipment, software and environments are required:

UP Squared 6000 board
Custom SPI flashing cable (instructions).
USB 2.0 pin header cable for debug uart output. OR Make your own.
DediProg SF100 or SF600 programmer
Linux host (see Building on Linux for details)
Internet access

Board Setup

Before You Start

Warning

As you plan to reprogram the SPI flash, it’s a good idea to backup the pre-installed BIOS image first.

Boot the board and enter BIOS setup menu to get familiar with the board features and settings.

Early boot serial debug console can be reached via UART2 located on CN49 header on the UP² 6000 board. Make sure you can observe serial output message running the factory BIOS first.

Note

To make your own UART debug adapter by direct wiring, refer to CN49 Header Pinout for UART2:

Pin	Signal
8	GND
9	UART_RX
10	UART_TX

Building

UP² 6000 board is based on Intel Elkhart Lake. To build:

python BuildLoader.py build ehl

The output images are generated under Outputs directory.

Stitching

Stitch SBL images with factory BIOS image using the stitch tool:

python Platform/ElkhartlakeBoardPkg/Script/StitchLoader.py -i <BIOS_IMAGE_NAME> -s Outputs/ehl/SlimBootloader.bin -o <SBL_IFWI_IMAGE_NAME> -p 0xAA000206

<BIOS_IMAGE>     : Input file. Factory BIOS extracted from UP Squared 6000 board.
<SBL_IFWI_IMAGE> : Output file. New IFWI image with SBL in BIOS region.
-p <value>       : 4-byte platform data for platform ID (e.g. 06) and debug UART port index (e.g. 02).

Note

StitchLoader.py script works only if Boot Guard in the base image is not enabled, and the silicon is not fused with Boot Guard enabled. If Boot Guard is enabled, please use StitchIfwi.py script instead.

See Stitch Tool on how to stitch the IFWI image with SBL.

Slimbootloader binary for capsule

Creating Slimbootloader binary for capsule image requires the following steps:

Build SBL for UP² 6000:

python BuildLoader.py build ehl

Run stitching process as described above to create a SBL IFWI binary sbl_up2_6000_ifwi.bin:

python Platform/ElkhartlakeBoardPkg/Script/StitchLoader.py -i <BIOS_IMAGE_NAME> -s Outputs/ehl/SlimBootloader.bin -o sbl_up2_6000_ifwi.bin -p 0xAA000206

Extract bios.bin from SBL IFWI image:

python BootloaderCorePkg/Tools/IfwiUtility.py extract -i sbl_up2_6000_ifwi.bin -p IFWI/BIOS -o bios.bin

Generate capsule update image FwuImage.bin:

python BootloaderCorePkg/Tools/GenCapsuleFirmware.py -p BIOS bios.bin -k KEY_ID_FIRMWAREUPDATE_RSA3072 -o FwuImage.bin

Triggering Firmware Update

Please refer to Firmware Update on how to trigger firmware update flow. Below is an example:

To trigger firmware update in SBL shell:

Copy FwuImage.bin into root directory on FAT partition of a USB key
Boot and press any key to enter SBL shell
Type command fwupdate from shell

Observe SBL resets the platform and performs update flow. It resets multiple times to complete the update process.

Flashing

Flash the IFWI image to UP² 6000 board using a SPI programmer. Header CN20 on the board should be used, see instructions for additional details.

Good Luck!
