# Protectli Vault VP2420 This page describes how to run coreboot on the [Protectli VP2420]. ![](VP2420_back.jpg) ![](VP2420_front.jpg) ## Required proprietary blobs To build a minimal working coreboot image some blobs are required (assuming only the BIOS region is being modified). ```eval_rst +-----------------+---------------------------------+---------------------+ | Binary file | Apply | Required / Optional | +=================+=================================+=====================+ | FSP-M, FSP-S | Intel Firmware Support Package | Required | +-----------------+---------------------------------+---------------------+ | microcode | CPU microcode | Required | +-----------------+---------------------------------+---------------------+ ``` FSP-M and FSP-S are obtained after splitting the Elkhart Lake FSP binary (done automatically by the coreboot build system and included into the image) from the `3rdparty/fsp` submodule. Microcode updates are automatically included into the coreboot image by build system from the `3rdparty/intel-microcode` submodule. ## Flashing coreboot ### Internal programming The main SPI flash can be accessed using [flashrom]. Firmware can be easily flashed with internal programmer (either BIOS region or full image). ### External programming The system has an internal flash chip which is a 16 MiB soldered SOIC-8 chip. This chip is located on the top side of the case (the lid side). One has to remove 4 top cover screws and lift up the lid. The flash chip is soldered in under RAM, easily accessed after taking out the memory. Specifically, it's a KH25L12835F (3.3V) which is a clone of Macronix MX25L12835F - [datasheet][MX25L12835F]. ![](VP2420_internal.jpg) ## Working - USB 3.0 front ports (SeaBIOS, Tianocore UEFIPayload and Linux) - 4 Ethernet ports - HDMI, DisplayPort - flashrom - M.2 WiFi - M.2 4G LTE - M.2 SATA and NVMe - 2.5'' SATA SSD - eMMC - Super I/O serial port 0 via front microUSB connector - SMBus (reading SPD from DIMMs) - Initialization with Elkhart Lake FSP 2.0 - SeaBIOS payload (version rel-1.16.0) - TianoCore UEFIPayload - Reset switch - Booting Debian, Ubuntu, FreeBSD ## Technology ```eval_rst +------------------+--------------------------------------------------+ | CPU | Intel Celeron J6412 | +------------------+--------------------------------------------------+ | PCH | Intel Elkhart Lake | +------------------+--------------------------------------------------+ | Super I/O, EC | ITE IT8613E | +------------------+--------------------------------------------------+ | Coprocessor | Intel Management Engine | +------------------+--------------------------------------------------+ ``` ## Useful links - [VP2420 Hardware Overview](https://protectli.com/kb/vp2400-series-hardware-overview/) - [VP2420 Product Page](https://protectli.com/product/vp2420/) - [Protectli TPM module](https://protectli.com/product/tpm-module/) - [MX25L12835F](https://www.mxic.com.tw/Lists/Datasheet/Attachments/8653/MX25L12835F,%203V,%20128Mb,%20v1.6.pdf) - [flashrom](https://flashrom.org/Flashrom)
