Running Ubuntu 16.04 on MeLE PCG03 Apo Mini PC

I completed my review of MeLE PCG03 Apo mini PC with Windows 10 about two weeks ago, and at the time when I tried Ubuntu, all I got was a black screen. MeLE said they would release an Ubuntu image for the board soon, so I did not investigate further. The company has now released Ubuntu 16.04 Desktop ISO via a link on Twitter together with (partial) instructions, and the company told me another company had worked on the image. I sent the link to Linuxium, as in the past MeLE or that other company used his work without asking. I turns out the ISO was identical to Ubuntu 16.04 Desktop ISO released in April last year.

linuxium@LINUXIUMONE:~/Downloads$ cmp -l ubuntu-16.04-desktop-amd64.iso.mele ubuntu-16.04-desktop-amd64.iso.canonical
linuxium@LINUXIUMONE:~/Downloads$

1 2	linuxium@LINUXIUMONE:~/Downloads$ cmp -l ubuntu-16.04-desktop-amd64.iso.mele ubuntu-16.04-desktop-amd64.iso.canonical linuxium@LINUXIUMONE:~/Downloads$

Anyway, I still got the black screen issue using that image, and that’s because I first failed to find the option in the BIOS to change boot to Linux. When the mini […]

Meizu Pro 7 is a Dual Camera Dual Display Android Smartphone

Smartphones with dual rear cameras are becoming more common, and we’ve see some smartphones in the past with an extra rear display such as Yotaphone 2. Meizu Pro 7 and Pro 7 Plus smartphones combines both features, but instead of using an E-Ink or other e-Paper display for the secondary display, Meizu used an 1.9″ AMOLED display that automatically turns on when you flip the phone, and can be used to check the time or notifications while the main display is still off. Meizu Pro 7 / Pro 7 Plus partial specifications: SoC – Mediatek Helio X30 deca-core processor with 2x cortex A73 cores @ up to 2.6 GHz, 4x cortex A53 cores @ up to 2.2 GHz, and 4x cortex A35 cores @ up to 2.0 GHz, as well as Imagination PowerVR 7XT GPU System Memory Pro 7 – 4GB LPDDR4x Pro 7 Plus – 6GB LPDDR4x Storage Pro […]

Hologram LTE Software-Defined Global Network for Cellular IoT Projects Starts at $0.40 per Month per Device

Cellular connectivity can be rather expensive, and in the IoT realms, new LTE standards are still evolving and you may want to manage your own mini cellular network, so ideally we would need a provider that offers both low cost and flexibility. Hologram LTE network does both as it’s a software-defined network, and pricing starts at $5 for the SIM card and $0.40 per month per device. The company also just announced that their network was available for global deployment with the service available in more than 170 countries via partnerships through over 200 cellular carriers. The SIM card supports automatic roaming and carrier switching, and spacebridge inbound tunnel access allows for secure remote programming and device management. The SIM card specifications are as follows: 2G/GPRS, 3G HSPDA, 4G LTE Read/Write Cycles: Min. 500,000 Operating Temperature: -25°C ~ 85°C Data Retention: Min. 25 years at 25°C Triple-cut for Mini, Micro, […]

Intel Curie Module, Arduino 101 Board Are Being Discontinued (Too)

Intel seems to have completely given up on its efforts to bring products specific to the Internet of Things. After discontinuing Intel Edison, Galileo and Joule boards & modules last month, forcing companies to look for alternatives, the company has now issued product discontinuance / end-of-life notices for Intel Curie Module and Arduino 101 board, itself based on the Curie module. The two product change notification notice can be found below for: Select Intel Curie Module Products – PDF Select Intel Arduino 101 Products – PDF The use of the word “Select” would normally mean some versions of the module and board won’t be affected, but I fail to see which ones here, as AFAIK there’s only one Arduino 101 board, and two variants of Curie modules, all three to be discontinued. Arduino 101 will be phased out faster with the following milestones: July 17, 2017 – Product Discontinuance Program […]

HiMedia Q30 TV Box Review – Part 2: Android 7.0 Nougat Firmware

HiMedia Q30 is an Android Nougat TV box powered by Hisilicon Hi3798MV200 processor, a cost-down version of Hi3798C V200 processor with the same CPU, a lower-end Mali-450MP GPU, about the same media capabilities, and less I/Os. I’ve taken pictures of the device and board if the first part of the review entitled “HiMedia Q30 (Hisilicon Hi3798MV200) Android TV Box Review – Part 1: Unboxing and Teardown“, so today, I’ll report about my experience with the device while running Android 7.0. First Boot, Setup, and First Impressions I’ve connected a USB 3.0 hard drive to the single USB 3.0 port, and filled the two other USB 2.0 ports with a USB keyboard, and a USB hub with two RF dongles for an air mouse and a gamepad. I added Ethernet, HDMI, and power cable to start the device. A typical boot takes around 25 seconds to the Android launcher below. That’s […]

Cubieboard7 Board Powered by Actions Semi S700 Processor Becomes a Full-Featured Devkit with DVK522 Expansion Board

Cubieboard6 was announced earlier this year with the same form factor as Cubieboard2 – which was popular a few years ago – by replacing Allwinner A20 with Actions Semi S500 quad core ARM Cortex A9 processor. CubieTech is about to launch Cubieboard7 based on the same design, except for the processor upgrade to the pin-to-pin compatible Actions Semi S700 quad core ARM Cortex A53 processor. I’ve also found out Cubieboard2/6/7 can be connected to DVK522 expansion board to provide easier access more I/Os like LVDS, RGB LCD, VGA, and so on. Let’s start with the Cubieboard7 (CB7) preliminary specifications: SoC – Actions Semi S700 quad core ARM Cortex-A53 processor with Mali-450MP4 GPU System Memory – 2GB LPDDR3 Storage 8GB eMMC flash SATA 3.0 port for 2.5″ HDD/SSD implemented via USB 3.0 switch and JMicron JMS578 USB 3.0 to SATA controller. micro SD card slot up to 32GB Video Output – […]
