  1. Is V4L2 for rk3288 encoder mainline or is there a patch set?
  2. Did some more digging and even though its an "old" product, its still produced for OEM customers using it for current products. The HDMI-IN is via a HDMI-to-CSI chip, Toshiba TC358749 HDMI IN -> MIPI CSI -> RK3288 This explains why its implemented as a webcam in android. The CSI variant already has a linux driver in mainline : https://github.com/torvalds/linux/blob/master/drivers/media/i2c/tc358743.c
  3. everything's easy.. AFTER you've done it
  4. ffmpeg with hw encoding 1080p/60 (some stutter) working on stock debian image don't have my board at the moment. process was: 1) get orange pi linux sdk and debian image 2) pull armbian latest 3) diff debian config, cherry pick HDMI, audo, encoders 4) diff kernel, cherry pick hdmi, audio, encoders 5) compile and flash if you don't want to tinker and 1080p30 is sufficient @ H.264: https://www.inforcecomputing.com/products/application-ready-platforms/qualcomm-snapdragon-600-inforce-6420t is $99 and you get helpful support
  5. Found an old (2015) Ugoos UT3+ / UT3 Plus with an rk3288 - the neat thing about this board is it has HDMI-IN ! Also has PIP Specs: I'm was eventually able to successfully screen capture @ 1920 x 1080 ~29 fps using the Android 5.1.1 firmware V3.0.7 for UT3+ https://mega.nz/#!cQpl0ICS!8EgHddI3_PXQsSe-TSrkHfxdHCmkbckNWBYuLhfuA7w The firmware crashes frequently and the painful part is the IR remote is required to start recording.. so I'll be porting gentoo / armbian to this device to turn this paper weight into a linux friendly screen capture device. It maybe also worthwhile to document the process and create an armbian porting guide. Aside, for those interested, its worth to mention the LKV373A HDMI / ethernet sender is a potential $30 HDMI screen capture alternate.

    Wayland on ARM SBCs

    Anyone seen any Wayland demos / guides for ARM SBCs ?
  7. Yes, I've used older RK3288 STB with HDMI-IN. In the end, went with a server motherboard with IPMI. It may be possible to use the serial console and an arduino or pi
  8. Add Raspberry Pi 4 with USB 3.0 adapter! RTL8153 works OOB on linux Modem <-> SBC <-> Switch <-> Devices. 900+ with NAT on multiple SBCs.
  9. Haven't decided on a final config becuase theres more testing to be done. Easiest would be Atomic Pi (x86), your fav minimal distro and a USB 3.0 to Gigabit Adapter, about $50 shipped in the US (not including power supply) Cant recommend any MIPS / ARM boards because it requires backporting netflow to your kernel and/or SIMD optimization. If you can do that, you can find the boards from the specs listed above and take into account the state of firmware/software to make an informed purchase.
  10. Success! Using a minimal distro and an SBC with min specs: + dual core @ 1.8 Ghz + DDR4 I was able to get 850+ Mbps firewall with QoS! Tested multiple methods: - integrated NIC + USB 3.0 Gigabit adapter - integrated NIC + PCI-e NIC - dual PCI-e NICs. For under $50 and under 15W Used this guide https://blog.tjll.net/building-my-perfect-router/ as a starting point. Used unbound for local dns reslover and a few other changes to traffic shaping and metrics; using prometheus and grafana There's still room for improvement, get power under 10W and maybe closer to 5W-8W. Lower cost if there was a board with integrated dual gigabit NICs !!
  11. I'm well aware. To be clear, I DO NOT expect ANYTHING from the community. If someone shares an interest and shares info/knowledge/code GREAT, happy to work together Just documenting my thought process here as it may be helpful to others and shed some insight into SBCs. Its important that we improve the visibility of products and manufacturers that listen to feedback, continually improve their products and work with the community, not expect any support to be handled by the community. HINT: If a board manufacturer lists forum/community under support - run! Run as fast as you can, as far away from them as you can.
  12. 2018-11-4 update Looks like Amlogic S905x2 SoC boxes are being released. quad Core A53 + 4GB + 32GB ROM + gigabit + usb3.0 ~ $57 + $10 USB 3.0 gigabit RTL8153 adapter = $67 Amlogic has decent BSP support and arguably better color reproduction, good for TV boxes, not relevant for network appliances Almost there, with armbian or arch support and $17 discount this COULD work.. don't get your hopes up
  13. Summary of potential boards: NXP FRDM-LS1012A 1x 800 Mhz 512MB 2x NIC - = $50 GlobalScale ESPRESSObin 2x 1.3Ghz 1 GB 1x WAN, 2x LAN - = $49 Linksys WRT1200AC (refurb) 2x 1.2 Ghz 512MB 1x WAN, 5X LAN 2x2 802.11ac = $40
  14. there have been VLAN CVE, rather encounter a security issue down the road - eliminate the problem with separate NICs. simple is always best Mainline kernel has support. You may lose some HW features but patching is not too hard, fortunately I only need firewall and QoS so that shouldnt be an issue. yup it was the the last board I ever helped kickstart. Now I wait to see if a board survives to mass production - like the Pi. I did back Parallella and was pleasantly surprised but that speaks to the caliber of the people working on the project. The founder is now a DARPA AI/compute project lead. I am pretty excited about the Ryzen V1000 boards coming out. if you look at the "companies" releasing the boards, you'll see its the same people under a different "brand" name. If you have lots of money to burn and want to encourage more bad boards, sure buy them all. I'll wait and see what survives. The smaller companies have to make a profit to survive unless they have tons of investment or are part of a much larger company. I mean look at Asus Tinkerboard, it still has issues and it used a few year old SoC and was made by a Tier 1 x86 motherboard manufacturer. Yes, have given up on any type of router boards - looking at the block diagrams and datasheets will reveal numerous issues.. Old x86 server I have around, it E3 Xeon uses ~25W since its server hardware. You can get older Xeons on ebay for very cheap.. But thats still 5x more vs a typically router ~5W. I forgot I also got a Linksys AC1200 refurb for $USD 40 which has an A385 . Was testing LEDE and ZFS on it. Will be putting debian on it now and will likely meet my needs. Yes, that's why industrial boards are expensive in addition to better spec-ed components. But I'm not looking for an industrial board - just one that has proper hardware at least, the software I can be fix. However, the NXP board I mentioned has an EXCELLENT BSP and hardware and support and its $50.. perhaps its subsidized as NXP to sell more chips since NXP is usually pretty expensive SoC-wise. I'd like to see any other manufacturer come out with something of comparable quality. Thank you for sharing. Most people don't know the difficult to bring a physical product, much less consumer electronics to market. Fortunately, one of my advisors helps manage supply chain for a certain fruit company. Their advice and experience was invaluable. After being burdened by one investor, I have learned to CAREFULLY read the legal and informal obligations of any contract/partnership and look for potential pitfalls, lest I be shackled again. One SoC vendor wanted free reign over our IP as they could be "independently" developing similar products and they had already released a similar product with a competitor. I declined. It sucked having to search for a new SoC vendor but it worked and we sold a good product. A year later we started talking again for a new project and they are more flexible having seen our success. Its unfortunate you couldn't manufacture in China, because then you could also do the regulatory testing/certifications in the area (HK, Taiwain or Shenzhen). The same testing/certification facilities used by Tier 1 motherboards manufacturers will provide testing services including the one you mentioned for USD $5K - $15K depending on what all you need. RF products will cost more. Glad to hear that you had an exit. Congrats Yes, out of all the community boards the EspressoBIN seems OK. The Marvell chips are fairly robust and the capabilities/performance aligns with the datasheet specs. However, after discussing the boards with GlobalScale I got an errie feeling similar to working with other SoC manufactures so I backed out and wanted to wait until launch. It was delayed over half a year and the end result is what you have now. They did release some Google Compute related boards so perhaps they are more focused on that but I got the sense they didn't really care about the community version board. I mean everyone wants Raspberry Pi level success and they seem to think the form factor is what does it, when its the fact they to long term support and committed part of their team to continue improving the BSP. "More wood behind fewer arrows". Rock64 says the same thing but shows different results. Releasing multiple boards with different SoCs with a small team will spread any small company too thin. Current SBC methodology is fire and forget and see what sticks. That generally works with software products but definitely not with hardware. Hence the bucket of EoL ARM devices that I and many others have sitting in the corner collecting dust. Hence why I refuse to support anymore campaigns without showing substantial thought into the product. Things do seem to be getting better as a couple mfgs are joining mainline kernel development and submitting patches and supporting projects like armbian. Just wish it didnt take companies 5 years to realize this.. The first "SBC" MK802 with Allwinner A10 was what changed the game back in 2012 and kicked off this SBC revolution and helped create a space which eventually gave us the Pi though the story with the Pi is it was built to get kids back into computers. Anyway I'm confident things will get better one way or another!
  15. Any updates on this? There has been significant progress on zfsonlinux recently, 0.7.11 resolves a few major issues and greatly improves performance on x86-64, I have a feeling it may be ready for "production" testing on ARM -- need to find a suitable board first! edit: Have you tried the Marvell ARMADA A8040 series from SolidRun? Supposedly good networking and storage controllers.
