Linus Torvalds has just announced the release of Linux 5.9 on lkml: Ok, so I’ll be honest – I had hoped for quite a bit fewer changes this last week, but at the same time there doesn’t really seem to be anything particularly scary in here. It’s just more commits and more lines changed than I would have wished for. The bulk of this is the networking fixes that I already mentioned as being pending in the rc8 release notes last weekend. In fact, about half the patch (and probably more of the number of commits) is from the networking stuff (both drivers and elsewhere). Outside of that, the most visible thing is a reinstatement of the fbdev amba-clcd driver – that’s a noticeable patch, but it’s basically just mainly a revert. The rest is really really tiny (mostly some other minor driver updates, but some filesystem and architecture fixes too). There’s just a bit more of those kinds of […]
LilyGO TTGO T-Watch K210 AIOT is a rather thick watch development kit based on Kendryte K210 RISC-V AI Processor and ESP32 WiSoC capable of performing AI workloads such as face detection using a USB power source. We first covered the development kit in June, and the company releases some small variants from time to time with the latest being TTGO Handheld T-Watch K210 with basically the same hardware, plus the addition of a handle that adds a power button, and a compartment for a 9V battery to power the watch/devkit. TTGO Handheld T-Watch K210 specifications: SoC – Kendryte K210 dual-core 64-bit RISC-V processor with 8MB RAM, AI accelerators Storage – 16MB flash, MicroSD card slot Display – 1.54-inch capacitive touch IPS screen connected over an 8080 interface Camera – Adjustable 2MP OV2640 sensor with 65-degree lens (optional 120-degree angle lens), AS312 “human” infrared sensor Connectivity – 2.4 GHz 802.11b/g/n WiFi and Bluetooth via ESP32 SoC over SPI/UART connection to K210 […]
Earlier this year, Seeed Studio introduced Wio Terminal a portable Arduino devkit with an LCD display, and expansion connectors and headers. The company is now selling a similar looking devkit but for different applications with Sipeed Maix Amigo portable 64-bit RISC-V development kit powered by Kendryte K210 RISC-V AI processor and equipped with an LCD display, two cameras, a few buttons, and several I/O headers and Grove connectors. Sipeed Maix Amigo specifications: SoC – Kendryte K210 Dual-core 64-bit RISC-V (RV64GC) processor with FPU @ 400 MHz (overclockable to 500MHz), 8MB SRAM, built-in AI accelerators for video and audio Storage – 16MB Flash, MicroSD card slot up Display – 3.5-inch TFT capacitive touch screen display with 480×320 resolution Camera VGA front-facing camera up to 30 fps (GC0328 sensor) VGA rear camera up to 60 fps (OV7740 sensor) Audio – Build-in microphone, optional 6-mic array USB – 1x USB Type-C port for power and programming Expansion 3x Grove ports with I2C, GPIO, […]
Linus Torvalds has just released Linux 5.8: So I considered making an rc8 all the way to the last minute, but decided it’s not just worth waiting another week when there aren’t any big looming worries around. Because despite the merge window having been very large, there really hasn’t been anything scary going on in the release candidates. Yeah, we had some annoying noise with header file dependencies this week, but that’s not a new annoyance, and it’s also not the kind of subtle bug that keeps me up at night worrying about it. It did reinforce how nice it would be if we had some kind of tooling support to break nasty header file dependencies automatically, but if wishes were horses.. Maybe some day we’ll have some kind of SAT-solver for symbol dependencies that can handle all our different architectures and configurations, but right now it’s just a manual pain that occasionally bites us. Anyway.. Aside from silly header […]
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 the small stuff that came in this last week since […]
After covering ESP32 based TTGO T-Watch-2020 programmable watch last month, I noticed LilyGO launched “TTGO T-Watch K210 AIOT” watch with Kendryte K210 RISC-V AI SoC and a camera for face detection and recognition, and while searching for information, I discovered another apparently similar “TTGO T-Watch K210“. But let’s look into the specifications to find out what the differences are. I first came across TTGO T-Watch K210 AIOT, so let’s have a look at some preliminary specifications for this model: AI Processor – Kendryte K210 RISC-V Dualcore 64bit with FPU with 8MB SRAM Storage – 16MB QSPI flash, MicroSD card socket Display I/F – FPC connect for external display (not included) Camera – 2MP OV2640 sensor Audio – MAX98357A Audio codec; CVSD & SBC audio encoding Connectivity – 2.4 GHz 802.11b/g/n WiFi 4 up to 150 Mbps, Bluetooth 4.2 BR/EDR and BLE Debugging – USB-C port via CP2104 Expansion UART, SPI, I2C, PWM, I2S I2C grove connector I/O Voltage – 3.3V […]
We’ve written about Kendryte K210 RISC-V AI processor, and Sipeed M1 module several times including in our getting started for Maixduino and GroveAI HAT boards for low-power AI inference such as object recognition or face detection using Arduino and Micropython programming. Shenzhen-based Tinkergen, a STEM Education owned by Seeed Studio, has now leveraged the low-cost processor to design MARK AI robot kit, where MARK stands for Make A Robot Kit, in order to processor an educational AI Robotics platform for children ages 12 years old and more. MARK will ship as a kit with the main parts and components including a chassis, a cover, two wheels, stepper motors, a pan-tilt camera with K210 processor, a 2.4″ LCD display, Grove & Arduino compatible MARKduino interface board, some sensors, and six AA batteries. Tinkergen offers pre-trained model to recognized objects like humans, books, pens, or smartphones, as well as traffic signs, numbers from 1 to 9, as well as domestic and wild […]
Sipeed has made several boards and kits based on Kendryte K210 RISC-V processor for low-power AI workloads such as face detection or object recognition including Maixduino board and Grove AI HAT that ship with camera and display. The company has now come up with MaixCube all-in-one development platform that houses Sipeed M1 module, a display, a camera, and a battery into a plastic case that’s somewhat similar to MStack M5StickV but with a larger display, and variations in the form factor and features. Sipeed MaixCube specifications: SoC – Kendryte K210 dual-core 64-bit RISC-V processor @ 400 MHz (overclockable to 600 MHz) with FPU, 8MB SRAM, KPU AI accelerator, APU audio processor, and FFT accelerator Storage – 128 Mbit flash, MicroSD card slot Display – 1.3″ TFT screen with 240×240 resolution Camera – OV7740 sensor (VGA camera) Audio – Built-in microphone, external speakers support; ES8374 audio codec USB – 1x USB type-C interface Sensors – Accelerometer Expansion – 4-pin Grove interface, […]
