Linux 5.19 Release – Main changes, Arm, RISC-V and MIPS architectures

Linus Torvalds has just announced the release of Linux 5.19. It should be the last 5.xx version, with Linux 6.0 coming for the next cycle: So here we are, one week late, and 5.19 is tagged and pushed out. The full shortlog (just from rc8, obviously not all of 5.19) is below, but I can happily report that there is nothing really interesting in there. A lot of random small stuff. In the diffstat, the loongarch updates stand out, as does another batch of the networking sysctl READ_ONCE() annotations to make some of the data race checker code happy. Other than that it’s really just a mixed bag of various odds and ends. On a personal note, the most interesting part here is that I did the release (and am writing this) on an arm64 laptop. It’s something I’ve been waiting for for a _loong_ time, and it’s finally reality, […]

Rock 5B RK3588 SBC preview – What works, what doesn’t in Debian 11

I’ve recently received an early sample of Radxa ROCK5 Model B (aka ROCK 5B) SBC part of the “Developer Edition” batch with 16GB RAM, and already showed the hardware and it booting successfully in Debian 11.

I’ve now spent more time with the board, and as part of the “debug party” tested performance and features in Debian 11. As one would expect, some things work fine, providing excellent performance, but others still need improvements.

ROCK 5B developer edition preview – Part 1: Unboxing and first boot to Debian 11

Radxa ROCK5 Model B (aka ROCK 5B) is one of the most anticipated Rockchip RK3588 single board computers due to its features set and relatively affordable price. It was first showcased in January, but it’s taking a while as the Cortex-A76/A55 SoC is a complex beast. The good news is that the public launch is getting closer as Radxa sent “developer edition” samples to developers and enthusiasts for a “debug party”. I was one of the recipients so, in this post, I’ll have a closer look at the latest revision of the board, and give it a quick try first before going into more details in the second of this preview. ROCK5 Model B unboxing I received the 16GB RAM version which should be the same for all board part of the “developer edition batch. Developers are invited to submit reports to Radxa forums, and since those are public, anybody […]

Armbian 22.05 release adds support for Orange Pi R1 Plus LTS, Radxa Zero & Rock 3A, DevTerm A06

The latest release of Armbian, version 22.05, is now out with hundreds of Linux kernel and user space-related bug fixes, a focus on stabilizing existing platforms, while still adding four new boards with Orange Pi R1 Plus LTS (RK3328), Radxa Zero (Amlogic S905Y2), Radxa Rock 3A (RK3568), and DevTerm A06 (RK3399). The community also added two new maintainers for ESPRESSObin and Radxa Rock Pi 4 (Model A) SBCs which should mean the images for those boards will be tested more regularly and potential issues fixed more quickly. You may want to read the more detailed changelog to see if any changes may impact the board(s) you are using. The new Armbian 22.05 release succeeds Armbian 22.02 outed on February 28, 2022. If you’d like to upgrade simply run those two commands on your existing installation:

sudo apt update
sudo apt upgrade

1 2	sudo apt update sudo apt upgrade

For new installation, browse the list of supported boards, select the Debian/Ubuntu image you’d […]

ROCK Pi 4 Model C+ SBC features 1.5 GHz Rockchip RK3399-T CPU, dual HDMI output

ROCK Pi 4 Model C+ is a single board computer (SBC) by a Rockchip RK3399-T hexa-core processor @ 1.5 GHz, equipped with 4GB RAM, and two micro HDMI ports to drive up to one 4K display, and one 2K display. It is yet another ROCK Pi 4 SBC from Radxa, and the first to use the down-clocked RK3399-T processor with other models based on Rockchip OP1 processor clocked at 2.0GHz (overclockable to 2.2/2.4GHz) or the traditional Rockchip RK3399 @ 1.8 GHz (overclockable to 2.0 GHz), and also the first of the family to offer dual HDMI output. ROCK Pi 4 Model C+ specifications: SoC – Rockchip RK3399-T big.LITTLE hexa-core processor with 2x Arm Cortex-A72 @ up to 1.5 GHz (up to 2.0 GHz overclock) 4x Cortex-A53 @ up to 1.4 GHz (up to 1.6 GHz overclock). Note the processor datasheet says the Cortex-A53 cores are limited to 1.0 GHz, but […]

Radxa E25 carrier board, 2.5GbE switch, and WiFi 6 router

Radxa E25 2.5GbE switch-Xiaomi AX6000 WiFi 6 router

I’ve just received an early sample of Radxa E25 dual 2.5 GbE carrier board for Radxa CM3 Plus (RK3568) system-on-module, a 2.5GbE TP-Link switch, and Xiaomi AX6000 WiFi 6 + 2.5GbE router. Here’s the back story before looking into the devices. I’ll soon have to review UP Xtreme i11 mini PC with a 2.5GbE port, and after writing about the upcoming ROCK5 Model B SBC with both 2.5GbE and WiFI 6/6E, I realized I should really get some hardware to test 2.5GHz and WiFi 6. So I started to ask what could be the best options for a $200 budget. While thinking about it, I remember Radxa was working on the Radxa E23 board with 2.5GbE, and adding a WiFi 6 USB dongle might be an option. But they told me Radxa E25 would be a better option with two 2.5GbE ports and support for WiFi 6, although that one […]

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 […]

Year 2021 in review – Top 10 posts and statistics

As per tradition, we’ll look back at what happened during the year in the last post, and see what 2022 may have in store, plus the usual statistics from CNX Software website. The biggest story of 2021 has to be the worsening of semiconductors shortages with extremely long lead times, prices of some components going up multiple folds, constant complaints on Twitter about availability and prices. I think I even saw a website, hopefully misconfigured, showing an estimated availability of a specific STM32 MCU in 2037. This also gave rise to opportunities and board redesigns, with MotorComm Ethernet chips replacing some Realtek chips in SBCs such as NanoPi R2C and Orange Pi R1S Plus LTS, and CH9102F showing up as a replacement for CP2104 in some IoT boards. We also got some interesting Arm processors, but sadly the high-expected Rockchip RK3588 got delayed by another year, although it’s getting really […]
