Here's how we build a LoRa SX1262 Driver for PineDio USB Adapter... And test it on Pinebook Pro

Build a Linux Driver for PineDio LoRa SX1262 USB Adapter

Hello pinetime devs,

As Hypnos never updated and it is a simple watch os, I opened another open source project for Pinetime, Zephyr now officially add pinetime board support, if you interested with Zephyr, join us to improve the open source project, just for fun!

https://github.com/ck-telecom/pinetime

I picked this little gem up on Amazon for $22.  It let's you program the eMMC modules using Etcher or Win32 Disk Imager.  I've installed the MrFixIt2001 image onto a 64GB eMMC and booted my RockPro64 right up.  Full disclosure, it doesn't seem to work with RockPro64 bootstrap images though, and I don't know why...  

Pine should add these to their online store, IMHO.

I just did a fresh install onto a 64gb SDCard for my RockPro64 as described here: https://wiki.pine64.org/wiki/ROCKPro64_S..._Installer


The first time I selected KDE GUI, after the install finished, I got the login dialog and logged in, but I never got the Desktop, nor could I ping the Rockpro64.

Then I started over and selected GOME as my GUI, this time I got logged into the Desktop alright, but after digging in a bit I found the Ethernet seems totally broken.  DHCP doesn’t work, and after configuring a static IPv4 configuration ("IP A" shows valid IP Config), I cannot ping IN or OUT of the rockpro64, nor do anything on the network.

The bootstrap installation went fine and was able to use DHCP to get an IP Address.  But I noted the installation took a LONG time.  Nearly 6-8 hours.

It seems something is wrong with the Ethernet drivers.

As a side note, I downloaded the mrfixit2001 image and the Ethernet works great:

    https://github.com/mrfixit2001/debian_desktop/releases

But, I would rather start with a clean fresh Debian install.

Another issue seems to be that if I install the bootstrap onto an 64GB eMMC as described here ( https://wiki.pine64.org/wiki/ROCKPro64_S..._Installer ) The system doesn’t boot.  However, if I install the mrfix2001 (as described above) image onto the same eMMC card, it boots fine.

Also, how do I manually configure the display resolution?  The RockPro64, does not properly detect my NewHaven 7” LCD NHD-7.0-HDMI-N-RSXN-CTU display, which has been properly detected by the Raspberry Pi 4 and the Asus Tinkerboard 2 and Asus Edge R.  I need to force the resolution to 800 x 480 to work with the NewHaven LCD.

Also, I find that after a soft reboot, I nearly always have to power my Dell monitor off/on, to get any display out of the RockPro64.

Anyway, any help you can led would be most appreciated.

Thank you,

Matt Dralle

Just an idea.. I know it's not Pine's core business and there are plenty of cheap okay wood burners, but it would be a nice extra to have a wood burning tip as the Pinecil is portable (with a powerbank/lipo) and an extra tip is more compact than an extra device..

Searching for a Pinecil/TS-100 wood burning tip, all I found was this hot-knife tip for cutting ropes, with no reviews on it's claimed wood burning ability:
https://1upracing.com/product/1up-racing...knife-tip/

Maybe affordable wood burning tips could be made to screw on to the hammerhead tip's shaft with an adapter that changes the thread to the one on commonly available tips (maybe not optimal for heat dissipation and long tip length)..
It seems 8-32 thread tips are common on cheap irons like Walnut Hollow in the USA. Other solid-point burners like TruArt use M4 x 0.7 thread tips. I don't know which ones are best available worldwide..

Previously it was a problem with the modem coming up as not ready when booting from the eMMC, but not when running from an SD card. Flashing the eMMC with a backup image fixed that.

Today another strange issue. Suddenly when trying to make an outgoing call the ring tone for incoming calls plays. Rebooted the phone and the same thing happens. As with the previous issue, this doesn't happen booting off an SD card and there have been no updates or configuration changes since the phone was last used.

OS is Mobian bookworm with updates as of 10/3/2021. Anyone else experience anything like this? Guess I could try updating the installation on the eMMC and see if the problem persists.

Who would like to use this PinePower "USBench" concept?

It functions like a compact "bench power supply" with USB C in- and output, powered by a standard USB PPS power source like PinePower. Since you can adjust voltage and current, you can also use it as a "universal DC power supply" to power all kinds of non-USB devices. Hopefully it would be user-friendly, cheap and compact enough to replace all household DC power supplies (that are not in constant use).


Background

The Programmable Power Supply (PPS) mode in currently available USB PD 3.0 power supplies allows a device to trigger 3.3V-21V in 20mV steps, with current limited at 50mA steps (source). With the recently announced USB Power Delivery 3.1, the coming years will bring USB C power supplies with the maximum heart-safe voltage of 48V at 5A.

I found a few niche products exploiting PPS to offer an adjustable power source:
XY-WPDT USB Charging Trigger
And interestingly this open source Arduino project, who knows Ryan Ma who designed this PD-micro may be interested to collaborate:
https://www.crowdsupply.com/ryan-ma/pd-micro


Concept

Like the XY-WPDT there is a USB C in- and a output port, and a small display. To make it practical in everyday use it does however need a case with knobs to set voltage and current, similar to bench power supplies. It should support up to 48V 5A, and maybe voltages below 3.3V by integrating a step-down converter.

Pushing a combination of buttons starts/stops "Child lock" mode. When "Child lock" is activated, all controls are blocked. When the USB cable is pulled from the output port, voltage is stopped until "Child lock" is deactivated. This is to avoid damaging devices by accidentally raising voltage or plugging in other USB devices. Like this the power supply becomes fit for use outside the lab to power all kinds of household devices like laptops, e-bikes, ...

Ability to simply restore settings for devices, by selecting their stored name.

The bench power supply functions an amateur would need for most repairs etc.

Accessories (cables):
- USB C to banana plugs
- USB C to screw terminal
- USB C to multimeter leads
- USB C to 5.5mm x 2.1mm barrel jack, with an assortment of barrel jack converters for use as a universal power supply

I am working on getting familiar with the working (Developer side) of Alpine-Phosh postmarketOS on the PinePhone.  I could use some help locating the Resources I need for development.  I have vast experience in older systems such as X-Window and  develop using openGL and some Homegrown UI tools.

 I worked for Singer Link Flight Simulation for 20 years for the most part on UNIX based systems, so I'm familiar with how the development side of the System works. I have done Low level Hardware interfaces and built Graphic Display for Instructor Panels and Cockpit Hardware (instrumentation).  My Programing is limited to COLBALT, C, C++,  ADA, C#

I am very new to this LINUX Environment and have done very limited Admin work.  I was planning on building a Scratch Linux to learn the system but saw that it would take to much time.  I need to get up to speed ASAP if anyone is willing to point me in the right direction.

I have Read most of the Alpine docs and the postmarketOS docs.
Familiar with APK utility.
Still don't know what I don't know!

This should get you from unboxing to a console.

At the time of writing, the graphics output is not functional in the Manjaro builds (but looks to be in the Android 11 Production Test Build for Quartz64 model A SBC)

There is a hint that the default baud rate of the serial port is 1.5mbaud in a warning on the Quartz64 Wiki (emphasis added)

Quote:Warning: Software for the Quartz64 is still early in development, and therefore currently lacks features such as the ability to produce video output. You are strongly encouraged to procure a 3.3V UART serial adapter capable of running at 1.5 mbaud[], such as the woodpecker if you want to use a Quartz64 at this stage.

Let's discusse improvements of hardware such as:

1) gps
2) nfc
3) nrf52840? (more flash and ram)
4) mag
5) gyro
6) PMIC for power consume
7) RTC battry
