Received Your Orange Pi One Board? You’ll Need to Tweak Your FEX File / script.bin

[Update: I’ve been informed that for some unknown reasons the voltage regulator outputs 1.3 and 1.5V instead of 1.1 and 1.3V on Orange Pi One with the settings and FEX file below, which could lead to overheating, and possibly damage the board under heavy load. A workaround is available here] [Update2: And the temperatures reported by the kernel are wrong (too low), so it’s better not to use the higher voltage at all. More details and tests @ http://forum.armbian.com/index.php/topic/617-wip-support-for-the-upcoming-orange-pi-one/page-4#entry5261] Orange Pi One is arguably the cheapest ARM Linux development board with networking available today for $9.99 plus shipping. It is very similar to Orange Pi PC with an Allwinner H3 quad core Cortex A7 processor, Ethernet, and HDMI, but has less memory as it comes with 512MB RAM instead of 1GB, and comes with a few less features too. The bad news is that Shenzhen Xunlong did not release any […]

How to Check CPU Throttling in Windows 10 or Windows 11

HWiNFO64_CPU_Throttling

Recent processors all have the ability to adjust the operating frequency to either decrease power consumption or make sure the processor does not overheat. That’s why for example Intel processors have a maximum junction temperature (Tj max) so that if this temperature is reached the processor can slow down (throttle) to cool things off and avoid damaging itself. That also explains why computers with the same processor, storage, and memory may have greatly different performance under load depending on their thermal design. I’m currently testing a fanless mini PC with an Intel Celeron N3150 Braswell processor, and yesterday I noticed the frequency would be stuck at 0.22 GHZ (yes, that’s 220 MHz) at all times, even when starting the web browser and loading long web pages. It was very slow, and I had a few “windows not responding” in the process. I checked the metal box temperature with an IR […]

Getting Started with NavSpark mini GPS Module

NavSpark_mini_BreadBoard

I noticed NavSpark mini GPS module a couple of weeks ago, and since it was free, not including $10 for shipping, I went ahead and ordered. Since the freebie got popular, SkyTraq took some time to ship it, and when they did they provide a “not trackable” tracking number, which I’m not sure what that means as I could track the parcel from Taiwan to Thailand using 17track website without issues. The packages included NavSpark mini and a USB to TTL module as described, so I insert both and connect VCC, GND, and UART as shown on the pictures on the product page. I also connected the GPS antenna from LinkIt ONE development kit to the uFL connector on NavSpark mini, as well as a micro USB to USB cable to my computer. If you don’t have such antenna, you’ll need to add the $9 GPS/GLONASS antenna on NavSpark website […]

Faster H.265/HEVC Video Encoding with Nvidia GTX960 GPU and ffmpeg

H.265 promises the same video quality as H.264 when using half the bitrate, so you may have thought about converting your H.264 videos to H.265/HEVC in order to reduce the space used by your videos. However, if you’ve ever tried to transcoding videos with tools such as HandBrake, you’ll know the process can be painfully slow, and a single movie may take several hours even with a machine with a power processor. However, there’s a better and fster solution thanks to hardware accelerated encoding available in some Intel and Nvidia graphics cards. For this purpose, GearBest sent me Maxsun MS-GTX960 graphics card, a second generation Maxwell GPU, that supports H.265 accelerated video encoding and promised up to 500 fps video encoding. So I’ve put the graphics card to the test in a computer running Ubuntu 14.04, and reports some of my findings here. Similar instructions can also be followed in […]

How to Resize Android’s Internal Storage Partition in Rockchip Devices

I installed Light Biz OS firmware on GeekBox yesterday, but I’ve quickly realized many applications such as Gimp Inkscape would not install due to the small 1.94GB “internal partition”, so I asked how to increase the partition size in GeekBox forums last evening, and got an answer overnight from “dewet”. The good news is that it worked so I’ll share the steps I followed in a computer running Ubuntu 14.04. It might also be possible to perform the same tasks within a Windows machine with Rorkchip’s Factory tools First let’s download the utils with relevant scripts and binaries:

Now copy your device or board’s firmware file “update.img” to the working directory, and unpack it:

The output should look like:

The files will be in the “output” directory. For our purpose “parameter” file, and especially the last line (CMDLINE) where we will want to adjust the userdata partition […]

How to Upgrade Rockchip Firmware in Linux for RK3288, RK3328, RK3368, RK3399, etc..

I’ve been looking for ways to upgrade firmware on Rockchip RK3368 based GeekBox in a computer running Ubuntu 14.04, but while they’ve provided firmware update instructions for Windows, which remains basically the same as upgrading firmware on Rockchip RK3288, there’s no such information for Linux. However, I could remember than Radxa Rock supported upgrade_tool utility, but since the tool linked on Radxa website might be outdated, I instead searched for some RKtools repository on Geekboxzone Github account, and I was lucky enough to find one. Here’s what I did to flash Light Biz OS to GeekBox with my Linux computer: Get the tools, and make sure upgrade_tool is there.

Download and extract the firmware, e.g. Cross_Lollipop_BizOS_V151208.7z:

Now connect a USB cable to the USB OTG port of your device or board. In case of GeekBox that’s the micro USB port. Now as the board is powered on, keep […]

GeekBox TV Box Unboxing and Development Kit Assembly Guide

GeekBox is both an Android TV box based on Rockchip RK3368 octa-core processor, and a Linux development kit thanks to the CPU module inside the device, a baseboard and various accessories. The company has sent me a review sample, as well as the accessories currently available. So today, I’ll have a look at the box, and show how to connect everything together. GeekBox TV Box Unboxing I’ve received two carton boxes via DHL, one with GeekBox itself, and the other with some accessories. You could use GeeBox has a TV box, and forget about its development attributes, as the device comes with the usual accessories include a case, an HDMI cable, an infrared remote control, and a 5V/2A power supply. I was really surprised by how small it was compared to other 64-bit ARM TV boxes recently launched on the market, and looks very much like a small router with […]

How to Upgrade SMA-Q Smartwatch Firmware

I’ve started testing SMA-Q smartwatch, and so far I’ve had lots of issues with Bluetooth connectivity. The watch can rarely pair with my Android smartphone, and I was unable to enable features like Anti-lost and Sedendary alerts as the app would always report there was no connection. The company has sent me instructions to upgrade the firmware, and it seems to have improved things a little. So first you need to install SMA Services app by scanning the QR code on the user’s manual, or download the apk by following this link. Once this is done you can register, or skip registration. Now go to Setting, and select Connect watch. You should see a circle as on the left side above reading Searching watch, then Bluetooth Connecting, before seeing a message the connection was successful. You’ll probably them want to tap on Upgrade app, before tapping on Firmware upgrade (local […]
