content: I'm liking the OrangePi as an upgrade from the RPi for my signal processing 'host pc' on a project I'm working on. However, what would be nice is to transfer the design and incorporate it onto my PCB itself - even if the cost is (obviously) going to be higher. The only thing that is keeping me from doing so, is the fact that the AllWinner H3s don't seem to be something that is 'normally obtainable.'I'm wondering: does anyone makes a similar kind of OSHW platform that is ARM based (1GHz+) with a processor that can be purchased from Mouser/Digikey?(Forum search didn't come up with any good results)

content: Did you look at Olimex Allwinner A20. They have full boards and SOMs. I have dozens of them installed in industrial applications. Cannot recommend highly enough. I'm doing signal analysis with SciPy / numPy and I'm mis-using the on board audio codec as an ADC.

I've actually thought about trying to be a US side supplier of OrangePis just for convenience, but if I migrate the SoC to be on my board directly, its important for the would-be maker to be able to source parts.

What I am in need of is as much computational power as possible, which has me looking at the 1GHz+ space. This is why the TI offering looks to be the optimum outcome. $22/ea in 1pc and clocks at 1GHz.

Take look at the whole range, The i.MX6S goes up to 1.2GHz and i.MX6DL goes up to 1GHzAlso there should be OSHW boards available with those parts. IMO wandboard is one of them.

content: i.MX6S has 624 balls and it's available only in that package, unless you need exactly that processor or need all it's features then go for something in a smaller package.i would suggest to go for the Sitara cpus from TI as others suggested above. If you don't need the industrial stuff like profinet,EtherCAT, EtherNet/IP (it has nothing to do with the regular 10/100/1000 ethernet which is present in all siatara 335x chips) then you can go for the lower ones - eg. you can have an AM3352 without 3D accelerator (ideal for headless systems) and without industrial interfaces under 15Eur (14.50eur in single piece @farnell) AM3354 with 3D and without industrial ifaces is approx 19Eur. and those Sitaras are coming in a friendly 324ball 0.8mm pitch backage.btw.. i'm on a similar boat . need a small , relatively cheap and readily available linux system, raspberry Pi zero is unobtanium in quantities bigger than one single piece. and all other single board machines are either too big or too expensive and all of them have too much HW i don't need. so currently i'm working on a design using the AM3352.

content: I have designed an allwinner board and I can share some details:-Chips can only be obtained via allwinner approved design houses; You can design your own boards but the design house has to be involved in the manufacturing or else they are not allowed to provide chips-Documentation is all in Chinese-They do some really funky things in their (application) designs-(simple) android adjustments are super expensive-You can't imagine how difficult it is to get rooted android from them-AWT provides the design houses a example schematic; like >90% of all available allwinner tablets / boards are this schematic with almost no change to it-AWT provides (orcad) sch and pcb files for DDR3 routing ; their length matching is out of spec according to their own DDR3 guideline document-For each AWT chip there is a specific design guide (all the design / datasheet files for the A64 core you can just find on google; normal path is NDA and payment)

content: I think there might have been a slight derailment. There is no interest in the _modules_ or SBCs themselves. It's just the reference design I'm after, that uses an off-the-shelf ARM that I can get, which I am after. The idea is to transfer the schematics of the relevant parts to my radio design, and skip the unneeded business of dealing with a module. I would be running ARMBian, so the Android stuff is a nonissue for me.Cheers!

content: Quote from: blueskull on December 02, 2016, 05:31:54 amWell, this is only fair if you are only interested in raw computing power. In a case like this, you most probably don't need (or want to) design a new board from the chip itself.On the other hand, the BB chip has some very nice features for embedded developments: both in hardware (such as the PRU and ADCs), and in documentation and support. And it is a very capable CPU, able to even implement SDR with GnuRadio (I did this myself). Most applications do not require much computing power beyond what the BB offers.

content: Quote from: blueskull on December 05, 2016, 12:03:49 pmI just wish they were priced better. The OSD3358 alone is the same price as a complete BB Green, but you still need flash etc.Seen an eMMC not in a fine pitch BGA lately? (Everything available I can find is 0.5mm pitch.)The 100LBGA at 1mm pitch which is pretty easy...All this could still be ok for small volume applications with reasonable margin, but that generally means some sort of industrial market at least in Oz... But then they're not available in industrial temp grade.

content: Quote from: Spikee on December 03, 2016, 01:19:00 amThe frightening thing is that both TI and the-company-formerly-known-as-Freescale are getting out of the ARM applications-processor market. TI is just leaving it (AFAIK no plans for ARMv8 chips), and Freescale is leaving by virtue of being bought out by NXP, then Qualcomm, which probably spells the death of future iMX development. I hope I am wrong but it does appear that the remaining players will all have similar policies toward the "little guy"--no data without NDA, no parts in small quantities, etc. Allwinner could start looking better in this scenario. When no company will document and publish as we used to take for granted, the next best choice may be a company which is bad at keeping secrets.

There are also a gazillion cool projects for which the BeagleBone Black and similar boards are well suited, even if outdated in terms of the CPU. Also, the PRU (Programmable Realtime Unit) on those processors is so insanely useful it's a real shame that TI is getting out of the biz. But anyway, the Beagle_____ ecosystem won't be going away anytime soon.

Until ARM-GCC was a thing, the whole family was priced out of the market for anyone smaller than 'large enterprise' in terms of compilers. Really, the whole sense of ARM comes off as "go away."Can anyone provide more of a source on TI getting out of the ARM processors? Best I can find is an article from 4 years ago regarding their OMAP processors.

It does not make sense to make very complicated chips and then sell some millions of it with less than 1 dollar profit on it, if you can sell that many opamps with more profit. As far as I understand, ARM for industrial is here to stay.

It's more of an appliance than a PC, I mainly needed the horsepower to crunch 8192pt FFTs, do some decoding, and post results to a website. This project frees a radio and PC, as it consolidates things into a single stand-alone unit.
