worth mentioning anyway, as ideas kept to oneself are useless ideas somehow noone else has replied so far, including ones i consider more competent on subject to me, ti am* soc seems like solid option. unsure if one wants to use c.o.t.s. board for industrial use, though? i mean as opposed to designing own pcb when others finally arrive, they might want to correct me, but next platform to consider (fbsd-support-wise) could be imx6 then there are allwinner socs which seem to be like more oriented towards consumer mobile devices and rpi-class (media players?) but nothing stops one from "abusing" readily available hw, if you ruggedize it and take appropriate precautions :) i hope you also found https://wiki.freebsd.org/arm and maybe other resources too (like related irc channels and forums) On Saturday, May 30, 2020, Dr. Rolf Jansen <freebsd@cyclaero.com> wrote: > Thank you for replying. The system and network management for our project happens to be ready. The interface board for the unit controllers with signal conditioning and the ADCs/DACs/DIOs over I=C2=B2C is in the prototyp= ing phase, and the only question left is now, with which SBC hardware we want to deploy everything. > Best regards > Rolf > > Am 30.05.2020 um 04:07 schrieb Sulev-Madis Silber <madis555@hot.ee>: > this might be not answer you're looking for, as it doesn't suggest new hw, but, maybe you're interested looking into my hobby project for new / fresh ideas, some of it can be seen at http://ketas.si.pri.ee/bbb/ sure, i kind of temporarly lost willpower or didn't have money to continue with that so it's outdated, but i hope at least some of it help, as it does somewhat similar thing (control server, watchdogged embedded clients doing i/o, encrypted connections, dual-partition emmc safe upgrades, cli, webui) > > > On Saturday, May 30, 2020, Dr. Rolf Jansen <freebsd@cyclaero.com> wrote: >> We are starting a new project of industrial device controllers. We want to utilize ARM-SBCs as unit controllers (and here a unit is one industrial device), and we need to attach at least 24 ADCs, 8 DACs and 16 DIOs to each unit controller (UC). Many unit controllers (eventually tenths to hundreds) would then communicate by a custom protocol over ethernet with a command and control server. The UCs and the C&C server would be operated by FreeBSD. Direct interoperability of the UCs with 3rd party IT systems is not a concern, integration needs to be done via the C&C server. >> >> Since the sample/update rate requirements are quite low, we are going the I=C2=B2C path, and initial testing has been done using the BeagleBone B= lack. It got 2 separate I=C2=B2C 400 kbit/s busses which helps already, avoiding = I=C2=B2C address conflicts. Yet, the 8 port I=C2=B2C switch TCA9548A is working very well, and we are now sure to be able to attach enough ADCs, DACs and DIOs to each unit controller. >> >> Although the initial viability tests were done with a BeagleBone Black running FreeBSD 13-CURRENT, we could start with another more modern SBC. >> >> First Question: >> >> What modern SBC with more than 1 I=C2=B2C bus and which can run FreeBSD = 13++ would you suggest? >> >> >> Now recently, I found the BeagleBone AI site https://beagleboard.org/ai/ <https://beagleboard.org/ai/>. This one got also 2 I=C2=B2C busses, and physically, with respect to a housing, it could be a 1:1 replacement for a BBB. It seems, this one is still too new for FreeBSD. I am very fond of the BB concept - for me it is much more appealing for industrial embedded applications than for example any RPI. However, the BBB came to age, and I would start a new project with it only, if there would be a reasonable chance for an upgrade path. >> >> Two more Questions: >> >> Is it reasonable to assume that FreeBSD would run on a BBAI in the future, let=E2=80=99s say in 2 to 3 years? >> >> Perhaps I could help porting FreeBSD to a BBAI.
