Introduction
|
|
============
|
|
|
|
This is a portable, 11.6" Ivy Bridge platform from HP. More information is
|
|
available on the [coreboot
|
|
documentation](https://doc.coreboot.org/mainboard/hp/2170p.html) - that page
|
|
said (on 16 August 2023) that GRUB hangs due to the `at_keyboard` module, but
|
|
this is no longer true; it's
|
|
[fixed](https://git.savannah.gnu.org/cgit/grub.git/commit/?id=830456a6e3b6ac92d10f9261177722a308652a1a)
|
|
in the latest GRUB revisions, and Libreboot's version of GRUB contains this fix.
|
|
|
|
**Unavailable in Libreboot 20230625 or earlier. You must [compile from
|
|
source](../build/), or use at least Libreboot 20231021.**
|
|
|
|
Build ROM image from source
|
|
---------------------------
|
|
|
|
The build target, when building from source, is thus:
|
|
|
|
./mk -b coreboot hp2170p_16mb
|
|
|
|
Installation
|
|
============
|
|
|
|
Insert binary files
|
|
-------------------
|
|
|
|
If you're using a release ROM, please ensure that you've inserted extra firmware
|
|
required refer to the [guide](../install/ivy_has_common.md) for that. (failure
|
|
to adhere to this advice will result in a bricked machine)
|
|
|
|
Set MAC address
|
|
---------------
|
|
|
|
This platform uses an Intel Flash Descriptor, and defines an Intel GbE NVM
|
|
region. As such, release/build ROMs will contain the same MAC address. To
|
|
change the MAC address, please read [nvmutil documentation](../install/nvmutil.md).
|
|
|
|
Flash a ROM image (software)
|
|
-----------------
|
|
|
|
If you're already running Libreboot, and you don't have flash protection
|
|
turned on, [internal flashing](../install/) is possible.
|
|
|
|
Flash a ROM image (hardware)
|
|
-----------------
|
|
|
|
**REMOVE all power sources like battery, charger and so on, before doing this.
|
|
This is to prevent short circuiting and power surges while flashing; although
|
|
the flash is socketed, hot-swapping is generally a bad practise and must be
|
|
avoided.**
|
|
|
|
Otherwise, external flashing is simple, but *quite different* from most
|
|
laptops! The flash is a SOIC8 IC like you'd expect, but it's *in a socket*.
|
|
|
|
Remove those two screws and cover on the underside, and then the flash is in
|
|
this socket which you can open:
|
|
|
|

|
|
<img tabindex=1 class="l" src="https://av.libreboot.org/hp2170p/hp2170p_socket.jpg" /><span class="f"><img src="https://av.libreboot.org/hp2170p/hp2170p_socket.jpg" /></span>
|
|
|
|
For general information, please refer to [25xx NOR flash
|
|
instructions](../install/spi.md) - that page refers to use of socketed flash.
|
|
|
|
For this board, you can use a Raspberry Pi or similar flasher if you wish, wired
|
|
to a spring socket adapter (SOP to DIP adapter) in a breadboard. In my case, I
|
|
opted for use of a 3.3v-modded CH341A device.
|
|
|
|
<img tabindex=1 class="l" style="clear:left;" src="https://av.libreboot.org/hp2170p/ch341a_socket_soic8.jpg" /><span class="f"><img src="https://av.libreboot.org/hp2170p/ch341a_socket_soic8.jpg" /></span>
|
|
|
|
Here, the flash is inserted into the SOP to DIP adapter, which is then put into
|
|
the ZIF socket on the CH341a device. This is the black version which has 5V
|
|
logic levels, but it can (read: MUST) be modified for correct 3.3v logic levels.
|
|
The [main 25xx flashing guide](../install/spi.md) documents this; some other
|
|
models may already be 3.3v, or have switchable logic levels like on some newer
|
|
revisions of CH341A. Please ensure that you run it at the correct voltage.
