Introduction
|
||
|
|
============
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
HP EliteBook 2170p support was added to coreboot, in
|
||
|
|
the [coreboot 4.20.1 release](https://doc.coreboot.org/releases/coreboot-4.20.1-relnotes.html)
|
||
|
|
and Libreboot recently [updated](update202308.md) to a revision past that
|
||
|
|
release.
|
||
|
|
|
||
|
|
I'm very pleased to announce that Libreboot now *fully supports* this machine!
|
||
|
|
It was added in this patch:
|
||
|
|
<https://browse.libreboot.org/lbmk.git/commit/?id=f8f77cb2886331d1b8b26d88d2407e2f85dc59a2>
|
||
|
|
|
||
|
|
Information about the board can be found on the coreboot documentation:
|
||
|
|
<https://doc.coreboot.org/mainboard/hp/2170p.html>
|
||
|
|
|
||
|
|
This will be available in the next Libreboot release. For now, you
|
||
|
|
can [download Libreboot from Git](../git.md) and [build from
|
||
|
|
source](../docs/build/) if you wish to use this board. Read those instructions
|
||
|
|
first; with build dependencies then installed, you can build the board like
|
||
|
|
so:
|
||
|
|
|
||
|
|
./build boot roms hp2170p_16mb
|
||
|
|
|
||
|
|
Installation instructions are being written for Libreboot, but you can refer
|
||
|
|
to the coreboot instructions for now.

Socketed flash IC!
|
||
|
|
------------------
|
||
|
|
|
||
|
|
I love HP EliteBooks. Truly. This is the only 11 inch laptop I've ever seen
|
||
|
|
that has socketed SOIC8 flash:
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
I flashed it with my [3.3v-modded](../docs/install/spi.md#do-not-use-ch341a)
|
||
|
|
CH341A - if you read that page, it says CH341A is ill advised, but if the
|
||
|
|
voltage is correct, flashing it in a socket like this is actually what that
|
||
|
|
programmer is intended for.
|
||
|
|
|
||
|
|
Mine is the black one, which has to be modified for correct voltage. Revision 1.6
|
||
|
|
which is the newer green model, is either 3.3v already or has a switch on it for
|
||
|
|
that.
|
||
|
|
|
||
|
|
After removing the flash IC, I flashed it in a spring socket adapter (SOP to
|
||
|
|
DIP) inserted into the CH341A's ZIF socket:
|
||
|
|
|
||
|
|
i
|
||
|
|
|
||
|
|
Basically everything works, on this laptop, as you would expect. NOTE: that
|
||
|
|
coreboot page says GRUB hangs on keyboard init, as of 9 August 2023. However,
|
||
|
|
this is no longer true. GRUB has fixed this, courtesy of a patch that Riku
|
||
|
|
Viitanen sent them.
|
||
|
|
|
||
|
|
Other works currently in progress

|
More boards coming soon
|
||
|
|
-----------------------
|
||
|
|
|
||
|
|
I'm on a spree, adding more boards to Libreboot, especially HP EliteBooks.
|
||
|
|
|
||
|
|
I have these boards, that I'm working on and testing; they will be available
|
||
|
|
in future revisions of Libreboot:
|
||
|
|
|
||
|
|
* HP ProBook 6360b - it has been added today to Libreboot, but it's not yet
|
||
|
|
tested. Patch (WIP):
|
||
|
|
<https://browse.libreboot.org/lbmk.git/commit/?h=hp2170p_wip&id=7badbf224b4ac80f73bb64a39aef518d790848c4>
|
||
|
|
* HP Revolve 810 G1
|
||
|
|
* HP EliteBook Folio 9480m - it has been added already to Libreboot (WIP), but
|
||
|
|
currently does not boot (more testing needed - not sure what my problem is
|
||
|
|
yet, but it was added today). WIP patch:
|
||
|
|
<https://browse.libreboot.org/lbmk.git/commit/?h=hp2170p_wip&id=25477d9ed44cea19bca8a875a7e334e8d4fa01b3>

Another build system audit
|
||
|
|
--------------------------
|
||
|
|
|
||
|
|
I've also started another audit of the Libreboot build system; the [last
|
||
|
|
one](audit.md) was quite intense and a lot more work is going in for the
|
||
|
|
next release.
