x86 system-on-module features 1GHz DM&P Vortex86DX3 processor

DM&P Vortex86DX3 is an x86 embedded processor launched in 2015 that we’ve previously found in single board computers and mini PCs, but I’ve just noticed ICOP was offering the SOM304D3 system-on-module based on the single and dual-core versions of the Vortex86DX3 SoC. The SOM304D3 is available with 1 or 2GB DDR3 RAM, works in a wide temperature range (up to -40°C to +85°C), and is designed for space-constrained industrial applications, especially those requiring legacy interfaces like ISA, IDE, and/or a parallel port (aka printer port). SOM304D3 specifications: SoC – DM&P Vortex86DX3 single or dual-core x86 processor @ 1 GHz, 2D GPU System Memory – 1GB or 2GB DDR3 Storage – Optional 4GB eMMC flash; SPI flash for AMI BIOS 4x 76-pin board-to-board connectors: Storage – SATA 1.0, IDE, SD Display VGA up to 1920 x 1080 @ 60Hz TFT LCD up to 1024 x 768 @ 60Hz Audio – 1x […]

Raspberry Pi CM4 compatible module coming soon with Amlogic A311D CPU

Despite assurances by Eben Upton that there’s no supply shortage of Raspberry Pi CM4 modules for commercial and industrial customers, installations or projects requiring just a few modules may be out of luck. So alternatives are needed, and after seeing Rockchip RK3566-based SoMs compatible with Pi CM4, namely the Pine64 SoPine and Radxa CM3, Banana Pi is working on a Raspberry Pi CM4 compatible module powered by Amlogic A311D hexa-core Arm Cortex-A73/A53 processor. Banana Pi BPI-CM4 specifications: SoC – Amlogic A311D hexa-core processor with 4x Arm Cortex-A73 @ 2.0 GHz and 2x Arm Cortex-A53 @, Arm Mali-G52 MP4 (6EE) GPU, 5 TOPS NPU System Memory – 2GB/4GB LPDDR4 RAM Storage – 16GB eMMC flash (up to 128GB) Networking – Gigabit Ethernet PHY on-module, optional WiFi 5/6 module with on-board PCB antenna and external antenna 2x 100-pin high-density board-to-board connector (mostly) compatible with Raspberry Pi CM4 with 1x HDMI, 1x MIPI […]

DongShanPi One – A SigmaStar SSD202D system-on-module with a mini PCIe edge connector for GPIO, Ethernet…

DongShanPi One system-on-module features SigmaStar SSD202D Arm Cortex-A7 processor with 128MB on-chip RAM, a 128MB NAND SPI flash and a microSD card slot, an LCD interface, two USB Type-C ports, and a mini PCIe edge connector that exposes interfaces like Ethernet, USB, and GPIOs when connected to a baseboard. I noticed the module in Linux 5.18 changelog yesterday together with the Miyoo game console, with support being added by dgp (Daniel Palmer), a frequent commenter on CNX Software, who also happen to maintain the linux-chenxing community. The DongShanPi One is optionally offered with a baseboard equipped with an RJ45 port, four USB ports, an IR receiver, and plenty of GPIO headers for expansion.

Linux 5.18 release – Main changes, Arm, RISC-V, and MIPS architectures

Linux 5.18 is out! Linus Torvalds has just announced the release on lkml: No unexpected nasty surprises this last week, so here we go with the 5.18 release right on schedule. That obviously means that the merge window for 5.19 will open tomorrow, and I already have a few pull requests pending. Thank you everybody. I’d still like people to run boring old plain 5.18 just to check, before we start with the excitement of all the new features for the merge window. The full shortlog for the last week is below, and nothing really odd stands out. The diffstat looks a bit funny – unusually we have parsic architecture patches being a big part of it due to some last-minute cache flushing fixes, but that is probably more indicative of everything else being pretty small. So outside of the parisc fixes, there’s random driver updates (mellanox mlx5 stands out, […]

Linux hardware video encoding on Amlogic A311D2 processor

amlogic a311d2 h265 hardware video encoding sample

I’ve spent a bit more time with Ubuntu 22.04 on Khadas VIM4 Amogic A311D2 SBC, and while the performance is generally good features like 3D graphics acceleration and hardware video decoding are missing. But I was pleased to see a Linux hardware video encoding section in the Wiki, as it’s not something we often see supported early on. So I’ve given it a try… First, we need to make a video in NV12 pixel format that’s commonly outputted from cameras. I downloaded a 45-second 1080p H.264 sample video from Linaro, and converted it with ffmpeg:

ffmpeg -i big_buck_bunny_1080p_H264_AAC_25fps_7200K.MP4 -pix_fmt nv12 big_buck_bunny_1080p_H264_AAC_25fps_7200K-nv12.yuv

1	ffmpeg -i big_buck_bunny_1080p_H264_AAC_25fps_7200K.MP4 -pix_fmt nv12 big_buck_bunny_1080p_H264_AAC_25fps_7200K-nv12.yuv

I did this on my laptop. As a raw video, it’s pretty big with 3.3GB of storage used for a 45-second video:

ls -lh
total 3.3G
-rw-rw-r-- 1 jaufranc jaufranc  40M Aug  5  2011 big_buck_bunny_1080p_H264_AAC_25fps_7200K.MP4

ls -lh

total 3.3G

Now let’s try to encode the video to H.264 on Khadas VIM4 board using aml_enc_test hardware video encoding sample:
