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 […]
MediaTek unveils 5G RedCap solutions: M60 5G modem and T300 Arm Cortex-A35 SoC
MediaTek has introduced its first 5G RedCap solutions with the M60 5G modem and the MediaTek T300 Arm Cortex-A35 SoC design to bring 5G-NR to wearables, light-weight AR devices, IoT modules, and consumer and industrial Edge AI devices. 5G RedCap (Reduced Capability), part of 3GPP Release 17, aims to keep some 5G features such as low latency, low power consumption, enhanced security, and network slicing while limiting the bandwidth (to around 85 Mbps) in order to be used in IoT devices and products that may not need the bandwidth required by smartphones and computers, but would benefit from longer battery life and a smaller footprint. MediaTek claims to be the first company to unveil 5G RedCap chips with the M60 modem and T300 SoC. MediaTek M60 key features and specifications: 3GPP Release 17 standard 5G modem R17 UE power saving R17 Coverage enhancement R17 Small data transmission LTE & NR-FR1 […]
BP Doctor PRO review – A 2-in-1 smartwatch and blood pressure monitor
So far, If I wanted to monitor my blood pressure monitor and overall fitness, I’d use a Bluetooth blood pressure monitor (Koogeek BP2) plus a fitness tracker/smartwatch such as Weloop Key S3. It does the job, but WearWiz has come up with something much more compact with the BP Doctor Pro 2-in-1 device that acts as both a smartwatch/fitness tracker and a blood pressure monitor, and at $299, offers a cheaper alternative to the $500 FDA-approved Omron Heartguide. The company sent a sample to CNX Software for review, so we’ll have a look at the device and accessories, the Android app, and features such as blood pressure monitoring, HRM, SpO2 level monitoring, and more. The review is rather long, so if you are short on time, you may want to check the two sections: Blood pressure monitoring with BP Doctor PRO smartwatch Conclusion with Pros and Cons BP Doctor PRO […]
Pumpkin i500 SBC uses MediaTek i500 AIoT SoC for computer vision and AI Edge computing
MediaTek Rich IoT SDK v20.0 was released at the beginning of the year together with the announcement of Pumpkin i500 SBC with very few details except it would be powered by MediaTek i500 octa-core Cortex-A73/A55 processor and designed to support computer vision and AI Edge Computing. Pumpkin i500 hardware evaluation kit was initially scheduled to launch in February 2020, but it took much longer, and Seeed Studio has only just listed the board for $299.00. We also now know the full specifications for Pumpkin i500 SBC: SoC – MediaTek i500 octa-core processor with four Arm Cortex-A73 cores at up to 2.0 GHz and four Cortex-A53 cores, an Arm Mali-G72 MP3 GPU, and dual-core Tensilica Vision P6 DSP/AI accelerator @ 525 MHz System Memory – 2GB LPDDR4 Storage – 16GB eMMC flash Display – 4-lane MIPI DSI connector Camera – Up to 25MP via MIPI CSI connector Video Decoding – 1080p60 […]
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 […]
Linux 5.1 Release – Main Changes, Arm, MIPS & RISC-V Architectures
Linus Torvalds has just announced the release of Linux 5.1: So it’s a bit later in the day than I usually do this, just because I was waffling about the release. Partly because I got some small pull requests today, but mostly just because I wasn’t looking forward to the timing of this upcoming 5.2 merge window. But the last-minute pull requests really weren’t big enough to justify delaying things over, and hopefully the merge window timing won’t be all that painful either. I just happen to have the college graduation of my oldest happen right smack dab in the middle of the upcoming merge window, so I might be effectively offline for a few days there. If worst comes to worst, I’ll extend it to make it all work, but I don’t think it will be needed. Anyway, on to 5.1 itself. The past week has been pretty calm, […]
Mediatek MT7629 Dual Core Arm Processor to Power AC1900 Routers
MediaTek is working on a new dual core Cortex A7 processor that supports OpenWrt and targets AC1900 WiFi routers. That’s what I learned from a tweet by WidoraIoT detailing the main features of MediaTek MT7629 SoC as shown in the table below. So basically we have two Arm Cortex-A7 cores clocked @ up to 1.25 GHz, 8MB built-in? flash, HW accelerators and security/crypto engines, multiple Gigabit and Fast Ethernet interfaces, built-in support for 802.11n (WiFi 4) 3×3 MIMO and 802.11ac (WiFi 5) 3×3 MIMO, as well as various interfaces such as PCIe, USB 2.0, USB 3.0, and the usual slower I/Os like I2C, PWM and UART. A web search mostly shows code commits to Linux and U-boot, and we learn a few extra details such as MT7629 shares the same PCIe IP block as MT7622 dual core Cortex-A53 processor. It also reveals a forum post on Widora website with a […]
