Coreboot for Lenovo Thinkpad T440P with additional patches

coreboot README

coreboot is a Free Software project aimed at replacing the proprietary BIOS (firmware) found in most computers. coreboot performs a little bit of hardware initialization and then executes additional boot logic, called a payload.

With the separation of hardware initialization and later boot logic, coreboot can scale from specialized applications that run directly firmware, run operating systems in flash, load custom bootloaders, or implement firmware standards, like PC BIOS services or UEFI. This allows for systems to only include the features necessary in the target application, reducing the amount of code and flash space required.

coreboot was formerly known as LinuxBIOS.

Payloads

After the basic initialization of the hardware has been performed, any desired "payload" can be started by coreboot.

See https://www.coreboot.org/Payloads for a list of supported payloads.

Supported Hardware

coreboot supports a wide range of chipsets, devices, and mainboards.

For details please consult:

• https://www.coreboot.org/Supported_Motherboards

Build Requirements

• make
• gcc / g++ Because Linux distribution compilers tend to use lots of patches. coreboot does lots of "unusual" things in its build system, some of which break due to those patches, sometimes by gcc aborting, sometimes - and that's worse - by generating broken object code. Two options: use our toolchain (eg. make crosstools-i386) or enable the ANY_TOOLCHAIN Kconfig option if you're feeling lucky (no support in this case).
• iasl (for targets with ACPI support)
• pkg-config
• libssl-dev (openssl)

Optional:

• doxygen (for generating/viewing documentation)
• gdb (for better debugging facilities on some targets)
• ncurses (for make menuconfig and make nconfig)
• flex and bison (for regenerating parsers)

Building coreboot

Please consult https://www.coreboot.org/Build_HOWTO for details.

Testing coreboot Without Modifying Your Hardware

If you want to test coreboot without any risks before you really decide to use it on your hardware, you can use the QEMU system emulator to run coreboot virtually in QEMU.

Please see https://www.coreboot.org/QEMU for details.

Website and Mailing List

Further details on the project, a FAQ, many HOWTOs, news, development guidelines and more can be found on the coreboot website:

You can contact us directly on the coreboot mailing list:

coreboot's Issues

Backlight function doesn't work

kbl_on2.txt
kbl_on1.txt
kbl_off.txt

The original Lenovo firmware allows changing keyboard backlight parameters with ectool

low brightness
sudo ./ectool -w 0xd -z 0x42

high brightness
sudo ./ectool -w 0xd -z 0x82

disable backlight
sudo ./ectool -w 0xd -z 0x02

On coreboot this doesn't work at all. The backlight stays off in any case.

Crystallwell support

I've tried crystallwell CPUs and it's not supported on the release build. I'm quite new to this, but is there an option to choose during build to include crystallwell? The crystallwell chip I've tried is the 4960HQ.

How to add the intel microcode now?

How do I add the microcode after this commit 2f6d52e?

No start possible since version 1.2

Hi there,

my ThinkPad T440P has not started since the first alpha version of "v1.2". The screen remains black and there is no sound. I also tried to connect external monitors, which was unfortunately unsuccessful.

First I went back to version "v1.1".

I have installed an Intel i7-4910mq and no eGpu.

Thanks for the support.
:-)

T440p sd card reader not working

Can you please check if the SD card reader RTS5227 is working with coreboot?

I tried it on arch linux with different kernel versions (4.19 and 5.7) and kernel modules (rtsx_pci and rts5227-dkms).
I also tried it with coreboot and windows 10.
The drivers are installed correctly but the reader does not work.

Tianocore not booting

I managed to boot seabios payload but tianocore does not boot with https://github.com/coreboot/coreboot
Where is the t440p specific configuration stored in this repository so I can compare?

Headphone jack

I've heard that the headphone jack isn't functioning, has any progress been made on this?

Can't build today. Some issues with submodules.

I'm following this guide (https://blog.conor-burns.com/lenovo-t440p-coreboot/) but I get some errors below. It appears there are issues with submodules.

Boot options not saved

I want to report that "add boot option" or "change boot order" is not saved on reboot in release v1.1.
I think no settings are saved.

I flashed the 4MB chip according to https://doc.coreboot.org/mainboard/lenovo/t440p.html.

Internal flashing with flashrom is not supported on T440p or?
Great you did this port!

Issues building cross-compiler even though gcc-ada installed

Running this up on Arch Linux and I can't seem to build the i386 toolchain.

I've installed gcc-ada and all of the requirements for Arch Linux, it should be noted that I don't have any issues compiling the toolchain in the upstream coreboot.

When it gets to building GCC this is the error I get:
