# Protectli Vault VP46xx series
|
||
|
|
|
||
|
|
This page describes how to run coreboot on the [Protectli VP46xx].
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
## 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 Comet Lake FSP binary (done
|
||
|
|
automatically by the coreboot build system and included into the image) from
|
||
|
|
the `3rdparty/fsp` submodule. VP4630 and VP4650 use CometLake2 FSP and VP4670
|
||
|
|
use CometLake1 FSP (see [variants](#variants) section), so be sure to select
|
||
|
|
the correct board in the coreboot's menuconfig, otherwise the platform will not
|
||
|
|
succeed on memory initialization.
|
||
|
|
|
||
|
|
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]. The first version
|
||
|
|
supporting the chipset is flashrom v1.2. Firmware an 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 socketed 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 near the M.2
|
||
|
|
WiFi slot connector. Remove the chip from socket and use a clip to program the
|
||
|
|
chip. Specifically, it's a KH25L12835F (3.3V) which is a clone of Macronix
|
||
|
|
MX25L12835F - [datasheet][MX25L12835F].
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
## Known issues
|
||
|
|
|
||
|
|
- After flashing with external programmer it is always required to reset RTC
|
||
|
|
with a jumper or disconnect the coin cell temporarily. Only then the platform
|
||
|
|
will boot after flashing.
|
||
|
|
|
||
|
|
## Working
|

|
||
|
|
UART adapter present on board)
|
||
|
|
- SMBus (reading SPD from DIMMs)
|
||
|
|

|
## Variants
|
||
|
|
|
||
|
|
There are 3 variants of VP46xx boards: VP4630, VP4650 and VP4670. They differ
|
||
|
|
only in used SoC and some units may come with different Super I/O chips, either
|
||
|
|
ITE IT8786E or IT8784E, but the configuration is the same on this platform.
