This post is mainly to share my tests result, but I have two questions:

- Did someone managed to boot from this SSD? Boot from Intel 660p 2 TB works fine but not this one?

- I noticed that my tests on the Intel 660p 2 TB are slower than before any idea why?
I am using Armbian with linux kernel 5.15.93-rockchip64 #23.02.2, we might get better results on linux kernel v4?

Note: The RP64 has a PCIe NVMe v2.0 x4 (not a v3.0) the speed is limited and not representative of the SSD real performance.

I have playing around with gokrazy, a unikernal project for the RPi, and very interested to see if such a project is feasible with your new upcoming Star64 Risc-V SBC.  I have some assembly code that initialises the Pi, and first step would be porting this over.  Is the Star64 documented well enough for such a project, I know that the Pi benefits from being around for a long time.  I can see 4+1 cores? (JH7110 has 6 no?) and already keen to find some documentation in preparation for your launch.

Hi all

I can't seem to work out, is it required/recommended to install the package "libdrm-pinebookpro" or is the functionality/fixes that this provides now included in the mainline libdrm package?

I have been having some issue with OpenGL objects within a programme (Mixxx DJ software Waveform display) causing some problems.

Thanks in advance.

I'm trying to change from the bullseye repository to the bookworm, and I'm getting an error about the repository being unsigned. In /etc/apt/sources.list.d/mobian.list

I changed

deb http://repo.mobian-project.org/ bullseye main non-free

to

deb http://repo.mobian-project.org/ bookworm main non-free

but now when I run

apt update

I get

Does anyone know what might cause this?

My WiFi/Bluetooth daughter board just arrived today for my PINE A64-LTS V2 that I've been integrating into a project.  I've been using the SBC with a wired Ethernet connection for weeks (although that had its own challenges, I eventually had to limit it to 10/100) and finally now I'm trying to get wireless going.  Unfortunately, I cannot get it to work after several hours of troubleshooting and I'm hoping someone out there has some ideas.

First, the basics... Issuing uname -a produces this:

Hello,

Can anyone please tell me the length of the DC plug? I know the outer diameter is 5.5 mm and the inner diameter is 2.1 mm, but I can't find the length (or even a part number for J11 that I could check, since there's no BOM published).

I'm used to seeing an update around the 15th of each month on the Pine64 blog. Are those not happening anymore?

Are the updates somewhere else?

I have the ANSI pbp from the 2023 batch.  Updated the keyboard/trackpad firmware from here https://github.com/dragan-simic/pinebook...rd-updater.  Now I can't take screenshots.  It's not just that the F9 "Print Screen" key is unresponsive.  The actual function of taking screenshots seems to be completely disabled on this computer. 
And here's why I'm saying that: 
When F9 Print Screen failed, I thought, no problem:   I'll just use a dedicated screenshot app like flameshot, or use gimp, so I tried those workarounds but everything failed.  Black screen or error messages on all attempts, using multiple apps.  Gimp returned an error that said "all possible methods failed," or words to that effect.
I'm a heavy user of screenshots to reproduce financial charts generated on my local machine, for publishing.  If I can find a fix, this Pinebook Pro will become my daily driver.  Ideas?

My bad luck finally caught up with my computer’s, I’m down to a iPhone that I have not been able to master font.

My Dell laptop has bounce off the floor one too many times, Ubuntu doesn’t want to wake up, and I don’t have funds for a 6” tablet, so this Pinebook Pro looks real interesting, and would do all the messaging and browsing without any hassle with a small phone at double 7 I need a good terminal 

Any comments appreciated
