NanoPi R1S Dual Gigabit Ethernet Router Comes with 32-bit or 64-bit Arm Processor

FriendlyELEC launched NanoPi R1 SBC & Gateway earlier this year with Allwinner H3 processor, two Ethernet ports, as well as WiFi and Bluetooth connectivity. The design makes use of both Ethernet on the processor, but that also means on Gigabit Ethernet port had to be combined with a Fast Ethernet processor. The company has now added a USB to Gigabit Ethernet bridge to their latest NanoPi R1S board meaning it’s now a dual Gigabit Ethernet SBC, but with the caveat that the port behind the USB bridge is limited to USB 2.0 speed (480 Mbps), and with overhead the USB Ethernet bandwidth is around 330 Mbps. There are two versions of the board, namely NanoPi R1S-H3 and R1S-H5 with respectively Allwinner H3 32-bit processor, and Allwinner H5 64-bit processor. Apart from the different processors, both boards share the same PCBA and specifications: SoC NanoPi R1S-H3 – Allwinner H3 quad-core Arm […]

Giveaway Week – NanoPi M4V2 SBC & Metal Case Kit

Let’s finish giveaway week 2019 on a high with FriendlyELEC NanoPi M4V2 single board computer, and its metal case kit. The board features a Rockchip RK3399 processor with 4GB LPDDR4 RAM, and the metal case kit allows the addition of an NVMe M.2 SSD as well. I tested the mini PC with FriendlyCore Desktop based on Ubuntu 18.04, since at the time, Armbian was still not working with the updated board equipped with LPDDR4 memory, and Android requires an eMMC flash module which was not part of the kits I received. NanoPi M4V2 performed fairly well in the case, but the fan is quite noisy, and somehow the RAM bandwidth was almost half of the one in the earlier NanoPi M4 board with DDR3 memory, which is the opposite one would expect. Probably related to some software tweaks as explained in the comments section of the review. I received two […]

HLK-7688A OpenWrt Development Board Comes with an Audio Jack

We first tested MediaTek MT7688 MIPS processor in Mediatek Labs’ LinkIt Smart 7688 / 7688 Duo hardware development kits running OpenWrt in 2015 with the boards having a focus on IoT applications. A year later, Widora NEO board launched with an audio jack for connected audio applications, but AFAIK it’s not available anymore. There’s now another OpenWrt audio board based on the processor with HLK-7688A board featuring Hi-Link HLK-7688A module which we previously found in MatchBox LoRaWAN gateway. HLK-7688A board specifications: Wireless Module – HLK-7688A based on MediaTek MT7688 MIPS24KEc processor @ 580 MHz, and equipped with 128MB RAM, 32MB flash Storage – MicroSD card slot Connectivity 802.11 b/g/n WiFi 4 up to 150 Mbps with u.FL antenna connector 10/100M Ethernet Audio – 3.5mm audio jack; 4-pin speaker header, WM8960 audio codec USB – 2x Micro USB ports one USB 2.0 port and one for debugging & power Expansion – […]

Fix for Raspberry Pi 4 4GB model’s USB Ports not Working on Ubuntu 19.10

Ubuntu 19.10 server was recently released with official support for Raspberry Pi 4 SBC. Shortly after I read stories about the USB ports not working on the board, but it took another interesting turn as Canonical now explains the bug only affects RPI 4 with 4GB RAM, and USB works just fine on boards with just 1/2GB RAM. The issue has been identified and it’s been found to be a kernel bug with a solution in the works that being tested. In the meantime, you can access to your Raspberry Pi 4 4GB USB ports by limiting the memory to 3GB in /boot/firmware/usercfg.txt as follows:

total_mem=3072

1	total_mem=3072

Alternatively here’s the link to an updated kernel provided by Hui Wang with you want to test it out: I built a testing kernel, not only includes the fix for USB host, but also includes all new patches from https://github.com/raspberrypi/linux.git rpi-5.3.y branch (about 107 […]

Digilent Offers 2 Zynq-Based Linux Development Boards Supporting SYZYGY Expansion

Digilent Announces SYZYGY high-speed SBCs Digilent has announced two new SBCs that are ultra-high-speed and built to be more modular than its other boards. The company, which has a great deal of experience in Pmod lower speed FPGA standards has now entered the open-source, SYZYGY high-speed standards with its Eclypse Z7 and the Genesys ZU development SBCs. Background on the Digilent Zybo FPGA SoC SBC We reported on the Zybo development board FPGA SoC from Digilent and that seems to have lead to the latest format for the Eclypse Z7. Zmod There is also a release planned for the new Zmod modules, built to work with both the Eclypse Z7 and the Genesys ZU as SYZYGY compliant expansion modules. Opal Kelly and Zmod expansion The Zmods are Opal Kelly module standard, called SYZYGY, first seen in the Opal Kelly SYZYGY Brain-1 SBC. The standard was developed to jump the gap […]
