I did not find bl602 related forum, so let me post here

I've had time to play with pinenuts lately and wanted to share about these wonderfull boards (I use pinecones and Nut-01S).

I'd like first to thank Pine64 for providing this hw, and lupyuen for his documentation efforts (mostly on the SPI !)

At the moment, the Nut-01s is my favorite, it is so small and yet usefull on its own with its push-button and RGB led, you can power it on two AAA batteries and there you go ... It's main drawback is that it has not enough pins to drive SPI devices, for that I use the pinecone.

I have a main project to do a small e-paper display for the kitchen, using waveshare 1.53" SPI e-ink display, here are some photos of the HW

       

And the software can be downloaded here : https://git.sr.ht/~fdlamotte/homedisplay

There is not much for now, the little box can drive a remote vlc server through http, it displays songs in directory and playlist and controls loading and playing songs or webradios ... I had to adapt code from the epd driver, and used yxml to parse the http streams from vlc.

As I wanted to add gemini capabilities to my box, I dived a little more into gemini itself. Using mbedtls I've been able to get gemini page (directly from the https examples of mbedtls) and serve some data too from a pinenut. The gemini browser is not yet functional into homedisplay, I do not render the text yet to the e-ink and only watch it from the serial terminal

Here is the server proof of concept code : https://git.sr.ht/~fdlamotte/pinenut_gem

I did not manage to get it to work using mbedtls that comes with the SDK, there was some cipher negociation problems. So I used mbedtls from git and backported the necessary bits to make it work on the pinenut ... so as you might expect, it is a little hacky but it works, I can change the led color with a gemini request made from a streamline gemini browser (used gmnlm and castor)

I hope it will draw other people to have fun with these little chips !

This seems to be a similar problem to several bugs reported, but all seem to have been solved.

I have installed edge and updated. Selecting Poweroff or Reboot from the top menu drops me to a login prompt instead of power off. Pressing the stop button for <> 15 seconds completes the power off. Entering sudo poweroff (password) at a terminal has the same effect.

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?
