    Have been exploring Dingleberry Pi 2
     
    QC/Atheros IPQ4019 - more relevant here for the ARM folks - IPQ4019 is a quad core Cortex-A7@800MHz
     
    Buys us GigE on WAN/LAN ports, along with ATH10K for dual-band 802.11 a/b/g/n/AC Wave2 along with USB3.0 for the USB user facing port.
     
    BOM cost is higher, as it manf. costs with more layers, and more power needs - and numbers there do not make sense for an affordable board for this community - $100 GOGS there...

    Quick update on DingleBerry Pi...
     
    Schematics - done - It's essentially a respin of the QC/Atheros reference design into a Pi board form factor.
    Layout/Gerbers - done - 4 layer board, single sided - nice to have a friend with an Orcad license from Cadence.
     
    Specifics
    MIPS24kc @ 650Mhz - big endian 802.11n - ATH9K driver - 2*2:2 for 300Mbps at 2.4GHz (wide channels) - PCB trace antennas Two 100Base-2 Ethernet - WAN dedicated port, LAN on switched port One USB-A for peripherals MicroUSB for Power/Console 32MB SPI-NOR flash - uboot and OS 128MB SPI-NAND flash - extending FS for application and user space 64MB DDR2 RAM SW - OpenWRT Master on the ATH79 target Bootloader - uboot with Pepe2K mods (web server fail-safe)  
    The 4351 does have PCIe, but I've decided not to implement
     
    Performance Targets:
    Reference board is good for 100Mbps WiFi and NAT LAN/WAN performance so fairly balanced there. Power - 5V5DC, 1000ma for PS - right now with everything active on reference design, we're around 850ma at max load.  
    BOM is reasonable, COGS says we're around $50USD to cover the NRE and breakeven with 1K boards with kits (box, cables, boards, ac adapter)
     
    I will not build/ship at a loss... So the next step before doing the engineering sample boards it to gauge the potential market interest.

    markbirss reacted to _Luc4sss in OrangePi Zero H2 Ram Upgrade   
    Hi,
    First of all i'm NOT a software developer and i have NO one skill on this kind of board's hardware...
    I've a good soldering skill, so just for fun i've bought a new RAM module for my OrangePi Zero Board...

    I've bought a K4B4G1646E-BYMA RAM module and then i've replace the onboard module...
    All of the work gone fine, the OrangePi Zero still boot and work perfectly, but i was hoping to upgrade the RAM on the board...
    After the boot, in the welcome screen the, the RAM amount is now 512MB (494MB) and before was 256MB...
    The RAM amount is now increased, but not like expected...

    I've choose the K4B4G1646E RAM module because, theoretically, it was a 4GB RAM module...

    What's was wrong? I cannot upgrade the memory in this way? Have i to edit something in the FEX file?


    Thanks in advance,
    Luca

    Ps. my OrangePi Zero come without an inductor, that's why you see an horrible inductor in my board

    Since the PCB itself doesn't route the extra address lines to the SoC, you can't expect to see bigger DDR size than the one provided by manufacturer.
    And you're lucky that it still boot, because the extra address lines left unplugged on the DDR are floating, therefore any ESR on those lines could change the current bank and memory could becomes corrupted...

    Actually, nothing is wrong. You got exactly what you should expect.  The K4B4G1646E-BYMA is a 4 gigabit ram module.
     
    BTW: impressive that you can resolder a BGA at home. Congrats.

    Today I did clone and compile kernel 4.14 from:
    https://github.com/Lichee-Pi/linux/tree/zero-4.14.y
    with their standard setttings (.config)
     
    The resulting zImage ( 4.14.14-licheepi-zero+ ) does also work with Ethernet / Audio-Codec and the Tripple-Status-LED
     
    I did put the 4.14.y zImage as zImage_Kernel_414.zip on my GoogleDrive (see above for the link)
     
    I do like the small 23MB footprint of this small Linux (would like to see such Linux on a Router which normally do use OpenWRT - many of them have 128MB RAM, but less Mhz)

    markbirss reacted to ChrisK in NanoPI NEO / AIR   
    It should be noted, however, that such thick SILPADS are quite bad when it comes to thermal resistance. While in some cases using such a thick pad and some metal may be better than nothing at all, it is better to avoid them and find a better solution. Using thermal pads or paste or glue is mainly to bridge air gaps due to imperfect surfaces. That stuff isn't really that thermally conductive at all, it just happens to be better than air. The general rule is that such layers should be as thins possible.
     
    Using a small 14x14x10mm heatsink, attached with thermal glue, is very likely to be far better than a 4mm SILPAD and a big piece of metal. Nice, suitable heatsinks for the H3 would be these: http://www.ebay.de/itm/172290970476. Add a very small dab of heat conductive glue, for example http://www.ebay.de/itm/181026615992, then put on the heatsink, align it and finally press it down _really_ good (most of the glue should squeeze out on the sides). Let it sit for a while until it's cured, done.

    What do we know now? Not much  -- most importantly that some details will change and 'board available soon'.
     
    We have a H6 Product Brief available and a few selected developers already had a look into user manual (NDA situation right now, so not possible to get any answers from them  )
     
    So all we know is really just:
    H6 is limited wrt DRAM (2GB DDR4/DDR3/DDR3L max), I know the DRAM manufacturer from the modules in my Beelink X2 but have forgotten the name The Ampak module might be an AP6356S providing dual-band/dual-antenna Wi-Fi + BT 4.1 Gigabit Ethernet (H6 is said to have a 2nd Fast Ethernet MAC/PHY but no idea how/whether exposed here -- maybe available on pin headers to be combined with an external MagJack like it's possible on ROCK64 or NanoPi Duo)  One HDMI is a v2.0a output for sure, the other can be another HDMI output (LCD to HDMI converter) or maybe also a HDMI to TS input (depends on the type of chip behind the left HDMI port) eMMC on board One of the USB receptacles is blue (USB3 SuperSpeed), the other is USB2 and I would believe the remaining USB2 port is available on pins 36/38 of the mPCIe connector allowing to attach 'miniPCIe WWAN modems' (to be combined with the SIM card slot -- AFAIK these modems use USB at a 3.3V logic level) the mPCIe slot also exposes H6's single PCIe 2.x lane there's AV, optical audio out and an IR receiver (positioned IMO somewhat strangely since if rotated 90° on the PCB side next to its actual location OPi 3 Plus combined with a little enclosure would already make up for a complete TV box)

    Be aware that OPi Zero NAS expansion board has 2 USB connectors, but only the one at the center is a real USB host.
    The other USB connectors at left near the barrel power DC is a USB Input to allow connecting the USB Hub to Non-Zero boards with a Male-Male cable.
    Plugging anything in this USB Input on a OPiZero is somehow shorting the whole hub which is already connected thru the pins header.
