Please determine the version you want to build (HOTP or not).
For the Thinkpad x230 there are multiple maximized boards under
./boards, x230-maximized, x230-hotp-maximized and x230-hotp-maximized_usb-kb.
All those roms are externally flashable through their top and bottom rom images.
As opposed to Legacy boards produced ROM images, Maximized boards produced ROMs are totally valid ROMs, including a valid Intel Flash Descriptor (IFD), Ethernet Intel Gigabit configuration flash space fiaxating MAC to DE:AD:C0:FF:EE, a valid neutered Intel ME containing only BUP+ROMP modules which liberated space is given back to the BIOS (coreboot+payload) region.
x230 maximized boards need blobs to be downloaded and extracted from Lenovo prior of building the board configuration.
You can also download the ROMs directly from CircleCI
make BOARD=x230-maximized bootstrap
make BOARD=x230-hotp-maximized bootstrap
If running a supported OS (Debian-11/Ubuntu 20.04), have installed proper dependencies, ran the xx30 blobs download script prior of calling the above make commands for your chosen board flavor, 3 roms should have been created:
- A fully valid 12Mb rom to be flashed internally, also splitted into:
- A top(4Mb) ROM, to be flashed externally on the top SPI flash chip.
- A bottom(8Mb) ROM, to be flashed externally on the bottom SPI flash chip
Please continue with the flashing guide
