Yep. That’s right.
I downgraded to 4.21.0 (It took some editing of MrChromebox’s script to get it to download that version), and voila!, I have 7.67 GB now.
Oh, and the trackpoint works too!
It would be nice if the latest rom didn’t have that memory issue.
Do we know what is the latest version with correct RAM?
I reverted back to 4.21.0 as well and it shows correct RAM. But if a later version also works I’d like to flash to that one.
Hello, I’ve encountered the same issue. Could you please tell me how to modify the script? Thanks a lot.
This is what I did, but I’m sure there’s a simpler way.
Running Linux on your Thinkpad C13 Yoga chromebook, download the script from Mr.Chromebox and run it until it shows you the menu. Press “Q” to quit.
Edit the script. Delete the following two lines:
rm -rf sources.sh >/dev/null 2>&1
$CURL -sLO ${script_url}sources.sh
cd to /tmp
Edit the sources.sh script that should be in /tmp
Replace the line
export coreboot_uefi_morphius="coreboot_edk2-morphius-mrchromebox_20231203.rom"
with:
export coreboot_uefi_morphius="coreboot_edk2-morphius-mrchromebox_20231013.rom"
Go back to where your firmware-util.sh script is and run it again, this time flashing the firmware. It should flash the 20231013 firmware (which is the 4.21.0 version).
It’s been extremely helpful to me. thank you so much! 
That’s actually quite informative! I’ll be sure to direct other people here in the future.
Unfortunately, since downgrading to 4.21.0, my WiFi no longer works after waking up from sleep.
I’ll try 4.21.1-3
Currently, I am using the “coreboot_edk2-morphius-mrchromebox_20231126.rom” version , both the trackpoint and memory are functioning normally.
My WiFi has no issues after waking up from sleep.
4.21.1-3 is what I’m on- how are things working for ya?
I flashed 4.21.1-3 and get this: fastfetch now reports 7.21GB total in Ubuntu!?!
Now, this is miles better than 5.7GB, but it’s still weird that between 4.21.0 and 4.21.1-3 there was a 0.46GB lost, and between 4.21.1-3 and 4.21.1-4 there was another 1.5GB lost.
Trackpoint and WiFi after sleep work fine in 4.21.1-3
4.21.1-2 reports 7.67GB, trackpoint and WiFi after sleep work.
I’ll stay on 4.21.1-2 until someone figures out why is some RAM disappearing with some of these updates.
I have no clue what exactly the complaint is, because there is nothing specific here. The DMI outputs are correct. and I don’t know what “the OS only shows” means. Windows shows 8 different values for RAM depending on where you look and at what field.
On 4.21.1-2 firmware, Ubuntu htop reports 7.67 GiB total memory.
On 4.21.1-3 firmware, Ubuntu htop reports 7.21 GiB total memory.
On 4.21.1-4 firmware, Ubuntu htop reports 5.73 GiB total memory.
This is the exact same Ubuntu installation. I tried others (Arch, Fedora, Windows) and I get similar total memory numbers (within a percent or two).
I’ve uploaded a fixed -4 build and removed all prior versions. The previous build was a test build with 2GB VRAM which was inadvertently pushed to the public script. The corrected build has 256MB, vs 16MB on the earlier 4.21.x releases. The OS should report ~7.47GB total memory given 8GB-256MB and the binary to decimal conversion
Thank you, that’s amazing! I was suspecting that vram might have been the problem.
I tried flashing the new -4 build, but the checksum fails though. Have you uploaded the .sha1 file as well?
fixed
Thank you, that’s awesome! It works great.
Hello, could you please release a version with the TrackPoint enabled? Thank you very much.
I need to figure out how to best handle having two versions; ideally it would get fixed to work under Windows as well
Would this available new firmware have the trackpoint enabled in it? Likely not, correct? Would I have to uncomment something somewhere?
