Protectli Vault VP2420

This page describes how to run coreboot on the [Protectli VP2420].

Required proprietary blobs

To build a minimal working coreboot image some blobs are required (assuming only the BIOS region is being modified).

+-----------------+---------------------------------+---------------------+
| 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].
