Most of the code is taken from 2570p, adjusted with autoport, SuperIO from 8470p and inteltool, GPIO config from inteltool via autoport. The laptop works well under coreboot with SeaBIOS 1.16.1 payload, running Debian GNU/Linux with kernel 6.1.15.

# HP EliteBook 2170p
|
|
|
|
This page is about the notebook [HP EliteBook 2170p].
|
|
|
|
## Release status
|
|
|
|
HP EliteBook 2170p was released in 2012 and is now end of life.
|
|
It can be bought from a secondhand market like Taobao or eBay.
|
|
|
|
## Required proprietary blobs
|
|
|
|
The following blobs are required to operate the hardware:
|
|
1. EC firmware
|
|
2. Intel ME firmware
|
|
|
|
EC firmware can be retrieved from the HP firmware update image, or the firmware
|
|
backup of the laptop. EC Firmware is part of the coreboot build process.
|
|
The guide on extracting EC firmware and using it to build coreboot is in
|
|
document [HP Laptops with KBC1126 Embedded Controller](hp_kbc1126_laptops).
|
|
|
|
Intel ME firmware is in the flash chip. It is not needed when building coreboot.
|
|
|
|
## Programming
|
|
|
|
The flash chip is located between the memory slots, WWAN card and CPU,
|
|
covered by the base enclosure, which needs to be removed according to
|
|
the [Maintenance and Service Guide] to access the flash chip. Unlike
|
|
other variants, the flash chip on 2170p is socketed, so it can be taken
|
|
off and operated with an external programmer.
|
|
|
|
Pin 1 of the flash chip is at the side near the CPU.
|
|
|
|
|
|
|
|
For more details have a look at the general [flashing tutorial].
|
|
|
|
## Debugging
|
|
|
|
The board can be debugged with serial port on the dock or EHCI debug.
|
|
The EHCI debug port is the left USB3 port.
