DSOM-020R PX30 development board review – Unboxing, Benchmarks, and Zigbee gateway

Dusun IoT DSOM-020R PX30 is a development board based on the company’s 1.3GHz Rockchip PX30K quad-core Cortex-A35 module of the same name designed for industrial applications that emphasize reliability and power efficiency. The board comes with various ports and expansion capabilities with support for monitors, microphones, and sensors through its carrier board in order to create prototypes and develop software before integrating the SOM DSOM-020 PX30 system-on-module into your own custom carrier board and product. As the company stipulates on the website, the development board is suitable for AIoT equipment, vehicle control, gaming platforms, smart displays, medical equipment, vending machines, and industrial computers. Let’s start the review with an unboxing of the DSOM-020R PX30 development board to find out more. DSOM-020R PX30 development board unboxing Dusun IoT sent us a basic kit of the DSOM-020R PX30 development board for review with a carrier board, the DSOM-020 PX30 system-on-module module, a […]

Linux 6.2 release – Main changes, Arm, RISC-V, and MIPS architectures

Linux 6.2 has just been released with Linus Torvalds making the announcement on LKML as usual: So here we are, right on (the extended) schedule, with 6.2 out. Nothing unexpected happened last week, with just a random selection of small fixes spread all over, with nothing really standing out. The shortlog is tiny and appended below, you can scroll through it if you’re bored. Wed have a couple of small things that Thorsten was tracking on the regression side, but I wasn’t going to apply any last-minute patches that weren’t actively pushed by maintainers, so they will have to show up for stable. Nothing seemed even remotely worth trying to delay things for. And this obviously means that the 6.3 merge window will open tomorrow, and I already have 30+ pull requests queued up, which I really appreciate. I like how people have started to take the whole “ready for […]

Linux 5.16 Release – Main Changes, Arm, RISC-V and MIPS architectures

Linus Torvalds has just announced the release of Linux 5.16: Not a lot here since -rc8, which is not unexpected. We had that extra week due to the holidays, and it’s not like we had lots of last-minute things that needed to be sorted out. So this mainly contains some driver fixes (mainly networking and rdma), a cgroup credential use fix, a few core networking fixes, a couple of last-minute reverts, and some other random noise. The appended shortlog is so small that you might as well scroll through it. This obviously means that the merge window for 5.17 opens tomorrow, and I’m happy to say I already have several pending early pull requests. I wish I had even more, because this merge window is going to be somewhat painful due to unfortunate travel for family reasons. So I’ll be doing most of it on the road on a laptop […]

Linux 5.15 LTS release – Main Changes, Arm, RISC-V and MIPS architectures

Linus Torvalds released Linux 5.15, an LTS version, this past Sunday: It’s been calm, and I have no excuse to add an extra rc, so here we are, with v5.15 pushed out, and the merge window starting tomorrow. Which is going to be a bit inconvenient for me, since I also have some conference travel coming up. But it’s only a couple of days and I’ll have my laptop with me. Sometimes the release timing works out, and sometimes it doesn’t.. Anyway, the last week of 5.15 was mainly networking and gpu fixes, with some random sprinkling of other things (a few btrfs reverts, some kvm updates, minor other fixes here and there – a few architecture fixes, couple of tracing, small driver fixes etc). Full shortlog appended. This release may have started out with some -Werror pain, but it calmed down fairly quickly and on the whole 5.15 was […]

Engicam PX30.Core SoM & devkit run Ubuntu 20.04 with mainline Linux

Linux 5.11 was released a few days ago, and it’s always interesting to check out the changelog to find new hardware platforms that support mainline Linux. One of those is Engicam PX30.Core SoM based on Rockchip PX30 quad-core Arm Cortex-A35 processor. Engicam also worked with Amarula Solutions to develop an Ubuntu 20.04 image with mainline Linux compatible with EDIMM 2.2 and CTouch 2.0 carrier boards for PX30.Core CPU module. Engicam PX30.Core SoM Specifications: SoC – RockChip PX30 quad-core Arm Cortex-A35 @ 1.2GHz with Mali-G31 MP2 GPU with support for OpenGL ES 1.1, 2.0, and 3.2, OpenCL 2.0, Vulkan VX 1.0, 1080p60 video encoding/decoding System Memory – Up to 2 GB DDR4 Storage – 4GB eMMC flash (other capacities on request) Audio – Audio codec on module SO-DIMM edge connector Display Interfaces –  24-bit Parallel RGB, 18/24-bit LVDS Camera interface – 4-lane MIPI-CSI for up to 8MP camera Audio – I2S […]

Linux 5.11 Release – Main Changes, Arm, MIPS & RISC-V Architectures

Linus Torvalds has released Linux 5.11 just in time for… “Valentine’s Day”: Nothing unexpected or particularly scary happened this week, so here we are – with 5.11 tagged and pushed out. In fact, it’s a smaller-than-average set of commits from rc7 to final, which makes me happy. And I already have several pull requests lined up for tomorrow, so we’re all set for the merge window to start. But in the meantime – and yes, I know it’s Valentine’s Day here in the US – maybe give this release a good testing before you go back and play with development kernels. All right? Because I’m sure your SO will understand. Linus Last time around, Linux 5.10 was an LTS release that added EXT-4 performance enhancements, improved post-Spectre performance, as well as the enablement of BCM2711 (Raspberry Pi 4) display pipeline, among other many changes. Some of the notable changes in […]

ROScube Pico SBC Runs Ubuntu & ROS on Intel Atom or Rockchip PX30 Processor

ADLINK has launched ROScube Pico SBC designed for robotics projects and powered by either an Intel Atom x5 Apollo Lake processor or a Rockchip PX30 Arm Cortex-A35 processor via their SMARC-compliant system-on-modules namely LEC-AL and as LEC-PX30. Both models run Ubuntu and ROS/ROS-2 operating systems simultaneously, and the company also provides NeuronBot robotics development and demo kit based on the SBC. ROScube Pico SBC and Devkit If ROScube Pico looks similar it’s because it appears to be based entirely on ADLINK previously announced ADLINK Industrial-Pi (I-Pi) SMARC Development Kit based on Rockchip PX30, and Vizi-AI development starter kit based on Atom x5-E3940 SoC and Movidius Myriad X VPU. Those are the specifications listed for ROScube Pico: SMARC Module For ROScube Pico NPS-1 – LEC-AL with Intel Atom processor, Intel Movidius Myriad X AI accelerator, 8GB LPDDR4 RAM, 32GB eMMC For ROScube Pico NPS-4 – LEC-PX30 with Rockchip PX-30 quad-core Cortex-A35 […]

Linux 5.7 Released – Main Changes, Arm, MIPS and RISC-V Architectures

OK… I’m a bit late on that one. Linus Torvalds released Linux 5.7 last week: So we had a fairly calm last week, with nothing really screaming “let’s delay one more rc”. Knock wood – let’s hope we don’t have anything silly lurking this time, like the last-minute wifi regression we had in 5.6.. But embarrassing regressions last time notwithstanding, it all looks fine. And most of the discussion I’ve seen the last week or two has been about upcoming features, so the merge window is now open  and I’ll start processing pull requests tomorrow as usual. But in the meantime, please give this a whirl. We’ve got a lot of changes in 5.7 as usual (all the stats look normal – but “normal” for us obviously pretty big and means “almost 14 thousand non-merge commits all over, from close to two thousand developers”), So the appended shortlog is only […]
