All about the PineCone BL602 RISC-V Bootloader... And how it loads the Application Firmware into XIP Flash Memory

BL602 Bootloader

Hello
I would to buy a pinephone do you an adress for france
I would be happt to have some comments from frenc users too
Thanks!!!

How exactly do I order a Pinebook?

It seems I am required to create a community account to purchase one, however, I am now told I do not qualify to purchase one either. 

Is there a guide somewhere?

Downloaded and flashed several images to an SD card, including Ubuntu Touch, Postmarket OS, and phosh, but phone just boots to pinephone logo and stays. what am I doing wrong?

Hi all,

As you all know, the ROCK64 runs notoriously hot for what it is. I've taken it upon myself to remedy some of that.

I've designed a 3D-printable top plate for the "Model B" open enclosure which allows you to mount a 40mm fan to it. Your fan will likely come with self-tapping screws, and the mounting holes are sized so that they should perfectly tap into them.

I know the board is mounted wrong in the photo, I've fixed it since



I've used PETG as filament, and a 0.6mm nozzle. PLA and a different sized nozzle should also work perfectly fine though. The fan in question is a 5V Noctua NF-A4x10 5V PWM; it comes with self-tapping mounting screws, and a USB adapter which runs the fan at full speed. This is good enough for me to test it for now, but the end goal is to do proper pwm fan control with a modified device tree.

Cooling performance is "okay"; due to the SoC being directly in the centre of the fan where airflow isn't ideal, it's less than expected. But I can now run cpuburn-a53 on it continuously without throttling. I seem to top out at 75°C in fact. Before I installed a fan, the CPU would get to 85°C and start throttling down to cool off.

My next steps are to design a circuit to drive the 5V PWM and Tacho (speed sensor) from the ROCK64's 3.3V GPIO. Then, I'll look into modifying the device tree so I can provide a patch which will speed up and slow down the fan as required using the kernel's "pwm-fan" driver, instead of a userspace software solution.

Since the Model B Open Enclosure is used by what I presume is all other Model B sized PINE64 SBCs, this particular 3D printable mod can be used for those too.

You can download the STL and STEP file from the wiki, I've licensed it as CC-BY 4.0: https://wiki.pine64.org/images/9/9d/Mode...cutout.zip

I'll try to keep this thread updated as I make progress on the 5V fan control electronics and the device tree.

I have an Armbian setup and have just got Panfrost and glamor X acceleration working. The result is actually _slower_ than it was previously --- it now takes about a second to update a full-screen rxvt terminal.

glxinfo -B shows that I'm using the 'Mali T860 (Panfrost)' device; glxgears shows 60fps and supertuxkart runs about a few frames per second, rather than the 1fps it was pretending to run at previously, so panfrost does look like it's actually _running_. The X logs look like the glamoregl has loaded and I don't see any errors. The panfrost and rockchipdrm modules are loaded and in use (non-zero reference counts). There's no reference to the software rendering engine.

I have:

Kernel: 5.12.6-rockchip64
libgl1-mesa-glx: 20.3.4-1
xserver-xorg-core: 2:1.20.11-1

Any suggestions as to what might be wrong here?

Is this the PSU for the Pine64 2GB A64 DB V1.1 2GB Rev B?

AC/DC Adapter Model: MX12W8-0502000UX.
Input: 100 - 240V ~ 0.35A 50 - 60 Hz.
Output: 5V - --- 2A.

Is this the the specifications for the power adapter for the Pin64 A64 DB V1.1 2GB Rev B?

Hi,

I bought a pinebook recently to play around and have a cheap laptop with me during travels and I have one major issue with it.

When I plug it in to charge it it will boot immediately. When I turn it off it stops charging also. This is very problematic as I planned on charging it using solar panels on a trip.

Is there a way to change this in the BIOS or something like that? I'm leaving in less than two weeks :/

Thanks!

On one of my 3-pack sealed PTs, the Bluetooth no longer seems to turn on.  It's on Infinitime 0.15.0, but I had the same problem on Infinitime 1.0.0. 

Is there a way to force Bluetooth to turn on (in part to see if that's still possible)?  I'm assuming Bluetooth still works on this unit, but it's always been a bit flaky: oftentimes I had to reboot to get BT to turn on ever since I started using this unit, but that no longer works.  Thanks.
