UEFI at Linaro Connect Vancouver 2018

Posted by Charbax – October 6, 2018

Unified Extensible Firmware Interface (UEFI) is a specification for a software program that connects a computer's firmware to its operating system (OS). UEFI is expected to eventually replace BIOS. Like BIOS, UEFI is installed at the time of manufacturing and is the first program that runs when a computer is turned on.

Google IoT Demo for Zephyr RTOS With TF-M Secured on Musca

Posted by Charbax – October 6, 2018

In this demo, the Trusted Firmware M is providing the SPE and JWT sign, Zephyr is providing the NSPE and The Google IoT application is running on Zephyr using secure services from Trusted Firmware M.

- Platform Security Architecture (PSA) is an IoI security framework being developed by Arm.
- Trusted Firmware M (TF-M) is an open source project to provide PSA compliant secure firmware for M profile devices.
- Zephyr is a Linux Foundation Collaboration Project to provide a small, scalable RTOS for connected, resource constrained device.
- Arm Musca-A1 subsystem based on Armv8-M which allows partitioning the SW execution in Secure and Non Secure domain.

Testing Arm with Arm with LAVA and 96Boards

Posted by Charbax – October 6, 2018

This is a mini LAVA lab running on a Dragonboard 410c to test any other 96Boards, this is a way to use Arm to test Arm boards in a simple affordable reproducible way.

OpenCV Color Segmentation and Tracking on DragonBoard 820c

Posted by Charbax – October 5, 2018

This demo is based and tested on the DragonBoard 820c, but should be able to work on varying platforms. In summary, it counts objects by color passing in the same direction through the camera field of view. It can count multiple objects simultaneously. The OpenCV functionality leveraged by this demo includes the following:

- Object segmentation using color
- Valid object identification by size
- Frame stitching to track and count multiple simultaneous moving objects by color
- Provides hooks to monitor performance when algorithm changes to - - OpenCV library calls are made for identification tuning
- Provides hooks to export results to the cloud

Dixie Dixon uses Nikon Z7 at Photokina 2018

Posted by Charbax – October 3, 2018

Dixie Dixon is a Pro Fashion Photographer, Nikon Ambassador, in this Interview she talks about using the new Nikon Z7 Full Frame Mirrorless camera during her Pro Fashion Photography shoot as part of the official Nikon Z7 launch campaign, adapting her favorite lenses including the Nikon 105mm f1.4, using the autofocus, using IBIS, using it for video. In this video I edit in some parts of her official Nikon Z7 video which shows "Behind the scenes" during her Nikon Z7 photo shoot. I also edit in some of the photos that she shot on there.

Sample filmed with Canon EOS R with 24-105mm f4 lens, testing Dual Pixel AF

Posted by Charbax – October 3, 2018

Sample video interview at the Canon Photokina 2018 booth filmed with the 24-105mm f4 on the Canon EOS R camera, since I filmed this in 4K30 it crops in by 1.8x. We also talk about the upcoming 28-70mm f2. This 24-105mm has in-lens stabilization which I thus am testing out in this video, the camera body has no IBIS though so the stabilization here is based on the lens only. EF-S lenses such as the 400euro 10-18mm for the 80D might be a good way to video-blog in 4K even with the 1.8x crop with the equivalence of an 18-32mm.

Canon EOS R at Photokina 2018

Posted by Charbax – October 3, 2018

Canon releases their new Full Frame Mirrorless camera system, the Canon EOS R comes with a new R Mount, with new lenses but it can also adapt all previous Canon lenses using their adapter. They have a very fast and precise Dual Pixel AF for very accurate video autofocus performance. It only has a single SD card slot, 4K video has an 1.8x crop. It does have IBIS neither but the lens based stabilization such as in the 24-70mm f4 kit lens is quite good. The positioning is about in the middle between a 6Dmark2 and a 5Dmark4. The new Dual Pixel CMOS AF sensor provides high autofocus performance and low light ability. The new mount also provides very high bandwidth allowing for new features in the lens for better performance. Canon emphasises that the EOS R system is designed to be future proof, this camera is the start for this new mount, possibly this could mean they might soon also provide more video centric camera without the 1.8x crop in 4K shooting, I'd hope with video features like in the new XF705 Pro Camcorder such as 110/160mbitps H265 HEVC for 4K60 HDR HLG 10bit 4:2:2 recording internal to dual SD card slots too.

Canon XF705, 4K60 10bit 4:2:2 HLG H265 HEVC Pro Camcorder

Posted by Charbax – October 3, 2018

First Pro level camera with H265 HEVC compression format, saving higher quality to a 110 or 160mbit/s to dual SD cards, 1" sensor recording HLG and PQ, it can record HDR (internal) and SDR (external) streams at the same time. Follow-up on the very popular XF305, it has 12G SDI connector, HDMI, 16Mbit/s IP streaming (even with 4K60 HDR). Dual XLR one at the front and one at the back. Slightly smaller and lighter than the XF305. The display can be swung onto one side or onto the other. It has Dual Pixel CMOS Autofocus which can also be used in manual focus mode with focus assist to help confirm proper focus in manual focus mode. Price is going to be around €7000 plus tax. Avid and other video editing apps will provide H265 HEVC support on launch. It also supports Canon Log3 for post production color grading. There is also H264 XF-AVC in 8bit 4:2:0.
