HarmonyOS development board shows up for $11

HarmonyOS development board

Last year, we noted the Hisilicon Hi3861 based HiSpark WiFi IoT development board with supports LiteOS and HarmonyOS that was available in China for just under $10, or as part of a devkit with baseboard and modules for around $60. Although not very practical, buying from Taobao was possible, but there’s now what appears to be a new revision of the Hi3861V100 based HarmonyOS development board in a wider form factor on Banggood for $10.99. Hi3861 development board specifications: MCU – Hisilicon Hi3861V100 32-bit RISC-V microcontroller @ up to 160 MHz with 352 KB SRAM and 288 KB ROM, 2 MB flash memory, and WiFI 4 connectivity; QFN-32 5x5mm package WiFi 802.11b/g/n standard up to 72.2 Mbps @ HT20 2.4 GHz frequency band (ch1-ch14).

OpenBSD 7.0 adds 64-bit RISC-V, improves Apple Arm silicon support

OpenBSD 7.0

OpenBSD 7.0, the 51st release of the UNIX-like operating system, was outed on October 14, 2021, with the introduction of 64-bit RISC-V support for HiFive Unmatched and PolarFire SoC Icicle Kit boards, as well as further improvements to ARM64 targets, notably for Apple Silicon Macs, although it’s not quite ready for general use yet. You’ll find the complete list of new features and updates on the OpenBSD website, but here are some of the highlights: New platforms – OpenBSD 7.0 add 64-bit RISC-V support Extended platforms arm64 Improvements to Apple Silicon Macs support USB 3, NVMe storage, GPIO driver, power management, etc… Enabled LEDs for the LAN7800 chip as found on the Raspberry Pi 3 Model B+. Added Type-C PHY controller found on the Rockchip RK3399. Implemented multicast support to Marvell ARMADA chips Various other changes to mips64, amd64, armv7, powerpc64 Kernel improvements Enabled dynamic tracker (dt) for GENERIC kernels […]

Zidoo M6 preview with Android 11

I’ve now had more time to play with Zidoo M6 Arm mini PC powered by a Rockchip RK3566 quad-core Cortex-A55 processor. I intended to review the device with Ubuntu, but I misunderstood, and Android 11 was pre-installed on the device. I was also told since this model is mainly for industrial control, I might want to focus on performance and connectors rather than how well all functions work. So this will not be a review, but rather a preview of Zidoo M6, since as we’ll see below there’s still more work do to fix all issues. As an industrial platform. some features like Google Services may not be needed or even desirable. First boot and Settings I’ve connected a USB keyboard for screenshots, MINIX NEO A2 Lite air mouse, an HDMI cable to my 4K TV, and the power supply to get started. I also add two AAA batteries to […]

Raspberry Pi 4, Rockchip RK3399 SBC’s get Arm SystemReady IR certification

RockPro64 RK3399 Arm SystemReady IR certification

The first hardware platforms getting Arm SystemReady IR certification for IoT Edge applications were announced a few months ago with namely NXP i.MX 8 Mini evaluation kit and Compulab IOT-GATE-IMX8 gateway being able to run off-the-shelf operating system images such as Fedora IoT, OpenSuSE Leap 15.3, and Debian 11 thanks to UEFI firmware. But following PinePhone Pro Linux smartphone announcement, and Pine64 October update, we also learned that Rockchip RK3399 based RockPro64 was also Arm SystemReady IR certified, and check Arm’s website directly revealed it was joined by Lenovo Leez P710 “Gateway” SBC, as well as Raspberry Pi 4 and Pi 400 platforms. Let’s check the details and see what off-the-shelf images each board has been tested with. Pine64 RockPro64 RK3399 SBC achieved SystemReady IR v1.0 Level 1 certification meaning it complies with some waivers and workarounds found in the errata document. The board has been successfully tested with Fedora […]
