RockPro64 RK3399 Board Linux Review with Ubuntu 18.04 + LXDE

Let’s do one more RK3399 Linux review using Pine64 RockPro64 development board. After shortly checking out the hardware, I’ll test Ubuntu 18.04 “Bionic” LXDE on the board, test 3D graphics acceleration, video playback, USB storage and network performance among other things on the board. RockPro64 Board Unboxing The board came in a cardboard package, and the sticker made it clear I had received the 2GB LPDDR4 version. Even after FriendlyELEC NanoPi M4 announcement, Rockchip ROCKPro64 is still the cheapest RK3399 development board around, so it should come as no surprise that the board does not come with any accessories by default. Another way to keep the price low was not to include any built-in storage apart from SPI flash, so instead most people will either boot from micro SD card or an eMMC flash module both of which need to be purchase separately. Another cost-saving is the lack of built-in […]

Linux 4.18 Release – Main Changes, Arm and MIPS Architecture

Linus Torvalds has just announced the release of Linux 4.18: One week late(r) and here we are – 4.18 is out there. It was a very calm week, and arguably I could just have released on schedule last week, but we did have some minor updates. Mostly networking, but some vfs race fixes (mentioned in the rc8 announment as “pending”) and a couple of driver fixes (scsi, networking, i2c). Some other minor random things (arm crypto fix, parisc memory ordering fix). Shortlog appended for the (few) details. Some of these I was almost ready to just delay to until the next merge window, but they were marked for stable anyway, so it would just have caused more backporting. The vfs fixes are for old races that  are really hard to hit (which is obviously why they are old and weren’t noticed earlier). Some of them _have_ been seen in real […]

FriendlyELEC NanoPC-T4 Board Kit Unboxing and Assembly

FriendlyELEC introduced NanoPC-T4 RK3399 SBC (Single Board Computer) last May for $129. The board comes with a Rockchip RK3399 hexa-core processor, 4GB RAM, 16GB eMMC flash, dual-band WiFi module and an M.2 socket with NVME (PCIe) SSD support. The company has now sent me the device with accessories for review / evaluation. In this post, I’ll check out all items received, and show how to assemble all components. NanoPC-T4 Board Kit Unboxing Let’s getting started, and open the package… I received two identical kits with two NanoPC-T4 boards, acrylic enclosure with spacers, screws and nuts, 12V/2A power supply, heatsink, and an RC-100 IR remote control. In theory, I also expected two WiFi antennas per kit since that’s part fo the kit in their website, but I did not see any. The remote control is an optional item. [Update: Ooops. I found the antennas inside the package for NanoPC-T4 board.] I’ve […]

Firefly Team Mailbag – Rockchip Development Boards and Accessories

T-Chip Intelligent Technology Co. is a hardware and software technology services company, and a few years ago they setup the “Firefly Team” to provide development boards running Android and/or Linux distributions to the maker community. If I remember correctly the company started with Firefly-RK3288 development board powered, as its name implies, by Rockchip RK3288 processor. Since then they’ve launched several other Rockchip development boards and modules, which I’ve covered on this blog. The company decided to send me some of their recent boards and accessories, so let’s have a look at what I received in my “mailbag”. I’ve also taken a few photos for those who did not watch the video or prefer close up photos. ROC-RK3328-CC “Renegade” Development Board The first board is ROC-RK3328-CC “Renegade” board which was first launched via a crowdfunding campaign by Libre Computer.  Both companies have been collaborating on some boards, and Libre Computer makes […]

LoStik USB Dongle Adds LoRa Connectivity to any Computer or Linux Board (Crowdfunding)

We’ve covered plenty of hardware with LoRa radio from gateways, to Arduino shields, tracker boards, and mini PCIe cards, but after reading an article on Time4EE this morning, I realized we never wrote about any LoRa USB stick. LoStik – previoulsy LoRa Stick – is an open source hardware USB dongle based on Microchip RN2903 / RN2483 LoRa module, and offered on CrowdSupply for $39. LoStik specifications: USB – USB 2.0 port LoRa Connectivity Microchip RN2903 – 915 MHz for  US, Canada, South America and Australia Microchip RN2483 – 868 Mhz for Europe Receiver Sensitivity – down to -146 dBm TX Power – adjustable up to +18.5 dBm Range – up to 15 km coverage in suburban and up to 5 km coverage in urban areas Misc – 2x user LEDs Power Consumption – 140 ma typical TX, 20 ma idle (with power LED) Dimensions – 80 mm x 25 […]

ODROID-N1 Canceled due to RAM Supply Issues, ODROID-N2 Coming Later this Year

Rockchip RK3399 powered by ODROID-N1 board was unveiled earlier this year with two SATA interfaces, up to 4GB RAM, HDMI 2.0 4K UHD output, Gigabit Ethernet,  and more. The plan was to launch the board in May or June for around $100. Sadly, the board has been canceled for reasons we’ll explain below, but the silver lining is that a more powerful ODROID-N2 should become available by the end of the year. The reason for the cancellation is all explained in a forum post in ODROID forums: After announcing the N1 board in February, we started to prepare all the components for the mass production. But Samsung and Hynix suddenly informed us 1GB DDR3 chip was End-of-Life phase and we couldn’t place any order. It meant we could not make 4GB model since there must be four DRAM chips mounted on the board. We could make a 2GB model only […]

Emcraft Introduces NXP i.MX 8M SoM and $299 Starter Kit

I first discovered Emcraft Systems in 2011 through their work porting uCLinux to Arm Cortex M3/M4 microcontrollers, and since then the company has kept on working microcontroller software and hardware, but also moved to Arm Cortex A class solutions. Like most embedded systems companies, Emcraft engineers have also designed their own NXP i.MX 8M system-on-module, but while many have still not announced pricing, and/or show “in development” or “early product announcement” in their product page, Emcraft has started taking pre-order for their i.MX 8M SoM Starter Kit for $299, with shipping scheduled for May 21, 2018 or before. Let’s check out SOM-IMX8M specifications first: SoC – NXP i.MX8M Quad processor with 4x Cortex A53 cores, 1x Cortex-M4F core, and a Vivante GC7000Lite GPU System Memory – 512MB to 4GB DDR3L/LPDDR4 SDRAM Storage – 4 to 64GB eMMC flash Connectivity – Wireless module supporting 802.11 a/b/g/n/ac 2×2 MIMO WiFi, Bluetooth 4.2, […]
