PineTime

PineTime is a $25 Smartwatch / Companion for PinePhone Linux Phone

We’ve recently seen Linux smartphones are coming in a few weeks or months, but the $150 PinePhone may not come alone, and soon be joined by a $25 companion, namely PineTime smartwatch. That’s what we learned through a tweet by Pine64 explaining the PineTime is a Linux smartphone companion that can run FreeRTOS or Arm Mbed operating systems.  It will be a side-project however, and the focus is still on PinePhone and Pinebook Pro, meaning it will take a while depending on the level of community engagement. Available information is limited to the discussion in the tweet at this stage, but we do know the watch will be made of zinc alloy &  plastic, come with a charging dock, a 20 mm wristband, an heart-rate monitor and last several days on a charge. We’ve also seen people interested in porting ZephyrOS to the watch, and others would like to make […]

Librem 5 vs Pinephone

Librem 5 & Pinephone Linux Smartphones to Launch This Fall

There are too highly anticipated Linux smartphones currently in development namely Purism Librem 5 and Pine64 Pinephone. The first one, based on NXP i.MX 8M processor is fairly pricey ($699) partly because of better specifications, but mostly because the company handles software development internally, while Allwinner A64 Pinephone has somewhat lower specifications, but a much lower $150 price tag as software development is done by the community. Neither phones are available, and until a few days ago there were no clear launch dates. This has now changed as Purism announced Librem 5 would start shipping on September 24, while Pinephone first batch is scheduled for mid-October, which should also be the date for the launch of pre-orders, and shipment will start in November. This sounds great, but be warned the first phones will be for enthusiasts who do not mind having a few defects and missing hardware/software features, and the […]

Software Development on Librem 5 and PinePhone Linux Phones is Progressing Nicely

Several Linux phones are expected this year including Purism Librem 5 and Pine64 PinePhone. Both companies have sent phone development kits out to developers a few months ago, and we are starting to see some nice progress for both phones. What made me write this post is an update from Purism comparing the boot time on Librem 5 running PureOS Linux distribution without specific optimizations yet, and HTC One Android smartphone.  Librem 5 smartphone devkit takes 13 seconds to get to the lockscreen, while the Android phone takes over 40 seconds. Fair enough, most people won’t boot their phone often, but it still nice to know it won’t take long to turn on the phone from power off state.  They also posted a progress report at the end of May saying calls are now working with better audio quality, fixed various issue with messaging in Chatty, work on Linux […]

Liberux NEXX

Liberux NEXX is a Linux smartphone with Rockchip RK3588S, 32GB RAM, 6.34-inch OLED (Crowdfunding)

Liberux NEXX is a Linux smartphone powered by a Rockchip RK3588S octa-core Cortex-A76/A55 processor coupled with 32 GB LPDDR4x and a 512GB eMMC flash, as well as a 6.34-inch 2400×1080 OLED display. We’ve seen other Linux smartphones in the past with the most popular likely being the Purism Librem 5 and Pine64’s PinePhone Pro. However, those are showing their age with older NXP i.MX 8M and Rockchip RK3399 SOCs, and the Liberux NEXX brings much-needed performance with a Rockchip RK3588S and 32GB of RAM, enabling mobile/desktop convergence to an extent. Liberux NEXX specifications: SoC – Rockchip RK3588S CPU – Octa-core processor with 4x Cortex-A76 cores @ up to 2.4 GHz, 4x Cortex-A55 cores @ up to 1.8 GHz GPU – Arm Mali-G610 GPU with OpenGL ES 3.2,  OpenCL 2.2, and Vulkan 1.2 support VPU – 8Kp60 video decoder for H.265/AVS2/VP9/H.264/AV1 codecs, 8Kp30 H.265/H.264 video encoder AI accelerator – 6 TOPS NPU […]

Linux 6.10 Release Changelog

Linux 6.10 Release – Notable changes, Arm, RISC-V, and MIPS architectures

Linux Torvalds has announced the release of Linux 6.10 on LKML: So the final week was perhaps not quote as quiet as the preceding ones, which I don’t love – but it also wasn’t noisy enough to warrant an extra rc. And much of the noise this last week was bcachefs again (with netfs a close second), so it was all pretty compartmentalized. In fact, about a third of the patch for the last week was filesystem-related (there were also some btrfs latency fixes and other noise), which is unusual, but none of it looks particularly scary. Another third was drivers, and the rest is “random”. Anyway, this obviously means that the merge window for 6.11 opens up tomorrow. Let’s see how that goes, with much of Europe probably making ready for summer vacation. And the shortlog below is – as always – just the last week, not some kind […]

FOSDEM 2024

FOSDEM 2024 schedule – Open-source embedded, mobile, IoT, robotics, RISC-V, etc..

FOSDEM – which stands for Free and Open Source Software Developers’ European Meeting – is a free-to-participate event where thousands of developers meet in Brussels on the first week-end of February to discuss open-source software & hardware projects. FOSDEM 2024 will take place on February 3-4 with 880 speakers, 818 events, and 66 tracks. Although I won’t attend, I’ve created a virtual schedule like every year with sessions most relevant to the topics covered on CNX Software from the “Embedded, Mobile and Automotive” and “Open Hardware and CAD/CAM” devrooms, but also other devrooms including “FOSS Mobile Devices”, “ Energy: Reimagining this Ecosystem through Open Source”, “RISC-V”, and others. FOSDEM Day 1 – Saturday, February 3, 2024 10:30 – 10:55 – Screen Sharing on Raspberry Pi 5 Using VNC in Weston and Wayland with the Yocto Project and OpenEmbedded by Leon Anavi In 2023, embedded Linux developers received eagerly awaited news: […]

NuttX RISC-V Star64 SBC

Star64 RISC-V SBC can now boot Apache NuttX real-time operating system

Most of the software development efforts on the more powerful RISC-V boards like Pine64 Star64 or StarFive VisionFive 2 have been focusing on Linux, but Lup Yuen Lee tried something different and managed to boot Apache NuttX real-time operating system on the StarFive JH7110-powered Star64 SBC. NuttX may not often make the news, but they are plenty of supported platforms, and we previously played with it on the Sony SPresense board, and reported about NuttX RTOS on ESP32, so it’s good seeing the open-source real-time operating system add support for the RISC-V architecture. [Update: RISC-V support was added many years ago, sometimes around 2016] The main trick to boot NuttX on the Star64 is to make U-boot think the NuttX kernel is the Linux kernel. That means a Linux image such as sdcard.img for the VisionFive 2 board will be used to get OpenSBIU and U-boot bootloaders, and the NuttX […]

Ubuntu Touch 20.04 OTA-2 adds support for Fairphone 3, Volla Phone X23, F(x)tec Pro1 X smartphones

UBPorts has just released Ubuntu Touch 20.04 OTA-2 based on Ubuntu 20.04 with three new phones supported namely the Fairphone 3, the Volla Phone X23, and F(x)tec Pro1 X with the latter being introduced in 2020 in a crowdfunding campaign claiming Ubuntu Touch support. Ubuntu Touch was initially an initiative by Canonical for desktop/mobile convergence, but when the company decided to refocus its efforts on cloud and IoT, the UBPorts community took over and eventually outed the first stable Ubuntu Touch release in June 2017. Work has continued since then and with the Ubuntu Touch 20.04 OTA-2 release, the community-supported distribution now supports 15 smartphones with the Fairphone 4, Google Pixel 3a and 3a XL, Oneplus 5 and 5T, OnePlus 6 and 6T, Vollaphone and Vollaphone X, Vollaphone 22, Xiaomi Mi A2, Xiaomi Poco M3, Xiaomi Redmi Note 7 and 7 Pro, besides the three new mobile devices added to […]
