How to Reduce SD Card Firmware Images Download Size

So I’ve just received a Roseapple Pi board, and I finally managed to download Debian and Android images from Roseapple pi download page. It took me nearly 24 hours to be successful, as the Debian 8.1 image is nearly 2GB large and neither download links from Google Drive nor Baidu were reliable, so I had to try a few times, and after several failed attempt it work (morning is usually better). One way is to use better servers like Mega, at least in my experience, but another way to reduce download time and possibly bandwidth costs is to provide a smaller image, in this case not a minimal image, but an image with the same exact files and functionalities, but optimized for compression. I followed three main steps to reduce the firmware size from 2GB to 1.5GB in a computer running Ubuntu 14.04, but other Linux operating systems should also […]

Roseapple Pi Board Powered by Actions Semi S500 Comes with 2GB RAM

[Update: I’ve finally received an answer: Lemon Pi and RoseapplePi makers are different companies, but they just happen to both use the same Actions Semi S500 reference design, and RoseapplePi is manufactured in Taiwan. The picture above is V1.0 board, but V1.1 will have some modifications] Lemon Pi development board was launched this May via a Indiegogo campaign. The board, based Actions Semi S500 quad core Cortex A9 processor, got fully funded by over 200 backers, but at the time of launch, some people questioned the used of the word “Lemon” in a product name, as it has several pejorative meanings, including “something that is useless or crappy”. I was contacted about a new Roseapple Pi board yesterday, and upon checking out the details, it looks exactly like the Lemon Pi, except it got upgraded to 2GB RAM, just like in Indiegogo… The board name on the PCB also reads […]

Using USB123 USBee AX Pro $5 USB Logic Analyzer with PulseView in Linux

USB123_USBee_AX_Pro

I recently wrote about an ultra low cost USB logic analyzer called USB123 USBee AX Pro, which I bought for $9.58 on DX, but I was later informed it also goes for $5.44 on Aliexpress including free shipping to most countries, and a few dollars extra for shipping to some other countries. Nevertheless, I’ve now received it, and instead of testing it with a closed source (and cracked) Windows software, I installed and ran PulseView open source graphical interface for sigrok, which I previously tested on UNI-T UT61E digital multimeter. The package includes USBee AX PRO mini logic analyzer, 10 dupont wires for 8 channels (digital only) and 2 ground pins, as well as a mini USB to USB cable for connection to a computer. The instructions to use the logic analyzer can be found on Sigrok Wiki. My computer runs Ubuntu 14.04, but Sigrok and PulseView can also be […]
