Anyone running Coreboot (e.g. System 76 open firmware) on their Clevo?

Just curious after watching this video:



It seems to be that if you have the Clevo PC50DD you essentially have a System 76 Oryx Pro, could you run the Coreboot open firmware?

Anyone successfully cross flashed?

I've found some discussions on Reddit but no confirmation from anyone who has managed to do so.

Or has anyone built their own Coreboot firmware for any other Clevo models?

 

Yeah, I was able to successfully convert my PC50DD to an Oryx Pro 6, but it required manually flashing the embedded controller and bios. You need multiple additional pieces of hardware to program both chips in place. This is risky and can brick the machine. You should use caution and do so at your own risk.

I followed the information on System76's github: https://github.com/system76/firmware-open.

Here was my buy list:

• Mega2560
• 24-pin 1mm pitch FPC board
• Male Header Pins
• 24-pin Flexible Flat Cable (I bought both Type A and Type B 20cm lenght, but I ended up using the type B opposite side cable.)
• CH341a
• You will also need solder and a soldering iron.

1. The first thing you will need to do is download all of the source files and compile the firmware using the first link above.
2. You also need to solder the mail headers to the FPC board.
3. Then follow these instructions to flash the Mega2560.
4. You will then need to follow these instructions to flash the embedded controller. When looking at the motherboard, I initially tried the rightmost pin as pin 1 because I thought the triangle was indicating pin 1. However, the flashing process would error out, I then used the leftmost pin as pin 1 and it succeeded.
5. You will then need to use these instructions to flash the bios. The bios is the chip just above the m.2 slots, it was under a piece of tape on mine and is labeled with u53.

EDIT:

By the way, I thought I would also link to where I bought mine since I have seen some posts suggesting there could be differences based on the vendor/reseller. I bought mine from rjtech.

After completing all of these steps you will want to install a fresh copy of Pop! OS. Only after reinstalling will the firmware manager in system setting recognize your machine as an oryx pro. From this point forward, all firmware updates can be updated from the settings window.
