Cubieboard4 (CC-A80) Unboxing and Getting Started Guide

A few samples of Cubieboard4 board may have been available in China in October 2014, but Cubietech only officially launched their Allwinner A80 development board about ten days ago, and you can buy it for $125 + shipping on sites like R0ck.me, Eleduino, Seeed Studio, and many other distributors. The company decided to send a sample for evaluation, and today I’ll start with a post showing some pictures of the kit, and explaining how to get started with assembly and first boot. Cubieboard 4 Pictures I received the board within two days after the company told me they would send a sample, as they used DHL. I also had to pay a bit of import tax and DHL’s handling fee. There should be CC-A80 box with the board and accessories, a white box for the power supply, and a power cord. There’s quite a few items to play with… The […]

When the new Radxa Rock Lite was announced for $59 in September 2014, it was one of the most inexpensive quad core ARM Linux development board available on the market. But ODROID-C1 board in December 2014, and especially Raspberry Pi 2 board in February 2015 changed all that, as these two quad core boards sell for $35 before shipping and taxes.

Sigrok and Pulseview in Ubuntu 14.04 with UNI-T UT61E Digital Multimeter

A couple of months ago, I received a new digital multimeter UNI-T UT61E that can send data to a computer via a serial cable, and allows you draw some nice charts. I’ve already done that in Windows 7 with the provided tools, and reported on the power consumption of some Chinese Android TV boxes. However, since I use Ubuntu 14.04 as my main operating system, Linux based tools would be more convenient, and open source sigrok-cli command line client and its graphical interface pulseview are supposed to support UT61E DMM, so I had to give it a try. A Quick Look at UNI-T UT61 Digital Multimeter Before going into Sigrok, I’ll quickly show what the multimeter received from DealExtreme . It took longer than expected to ship because of of included 9V battery, and at the first shipping attempt it was returned to DX, but after 8 weeks or so, […]

How to Build a Single Kernel Module (Driver) in Ubuntu

When I bought UNI-T UT61E digital multimeter, I planned to to use the open source tool Sigrok to capture voltage, current or resistance data with my Ubuntu 14.04 machine. Unfortunately, it was just not working for me and I kept getting some “Invalid function byte” error messages, so I asked on Sigrok mailing list, and since it worked for others, I was in big troubles. It turned out the RS-232 to USB dongle I used:

idVendor           0x1a86 QinHeng Electronics
idProduct          0x7523 HL-340 USB-Serial adapter

1 2	idVendor 0x1a86 QinHeng Electronics idProduct 0x7523 HL-340 USB-Serial adapter

was most likely to culprit, so I decided to buy another random USB to serial dongle on eBay, and after a few weeks I received it only to find out it had the exact same VID:PID, so I was out of luck. Finally, I gave up on Sigrok on Linux, and tested the power consumption of some Rockchip RK3288 & Amlogic S802 devices in a Windows 7 virtual machine running in my Ubuntu 14.04 […]
