#32030 — Openwrt on custom hardware

Do you know of some open hardware that runs officialy openwrt?

I'll try to explain my needs. I have to develop a board that runs Linux 
embedded for a VoIP application.
I need two Ethernet ports, LAN with active POE (where to connect a VoIP 
phone) and WAN (maybe with passive POE, where to connect a router).

So, the IP traffic could be routed to the external router connected to 
WAN or, internally, to a 4G modem.

So Linux should have three network interfaces: lan, wan and mobile.

It's a platform that seem very similar to a standard 4G router for SOHO 
application, but I need to customize software and hardware (I need to 
control some GPIO and UARTs).

Regarding the software, I could start from openwrt. However I don't know 
how to start with hardware. I saw some cheap platforms that run openwrt 
with schematics, but they usually use esoteric components, such as 
AllWinner or Broadcam CPUs.

The best would be to use a well supported Linux SOM that could simplify 
to custom electronics.

Any suggestions?

What about Raspberry Pi? Many models are supported, including Zero and
compute modules (easier to integrate into other designs):

You might like to try these people. Have been using a 3 port box of
theirs, nanopi, running a variant of openwrt, for a while now. Just
worked out of the box.

Not expensive and arrived within a few days. Usual disclaimer etc...

Yeah, I found these folks too in my researches. I will try their 
products a try. Maybe they could be available to re-design one of their 
product with some custom hardware I need.

Thanks for suggestion, as usual Raspberry is helpful for hobbyst and 
prototype, but I'm worried about serious productions where you need a 
product that can be purchased for several years.

In the past (around 3 years ago) I designed a product around CM1 that 
now is not available anymore.

As far as I know, CM3 should be backward compatible with CM1, or at least
very easily adaptable.

However, this is quite usual for these kind of modules, it doesn't matter
who makes them. I still remember some very disappointing experiences I've
had many years ago with some Bluetooth modules made by so-called
"respectable" manufacturers, and disappeared from Earth from one day to
another. Unless you use some very standard form factors such as PC-104 or
VPX (usually bigger and more expensive), you will face phase out.

At least the Raspberry foundation gives you an obsolescence statement for
their compute modules, for example they say that CM3+ will remain in
production until at least January 2028:

https://www.raspberrypi.com/products/compute-module-3-plus/

Besides, I believed that it was possible to buy the "bare" CPUs (in this
case the Broadcom BCM2837B0) to build your own boards, but apparently this
is not the case. These CPU do not even pop out if you search for them in
the Broadcom site! You can find some very sparse information online, but
basically it is all locked in between Broadcom and the Raspberry
foundation. Bummer.

pcengines.ch may have what you need.

They end-of-lifed their APU boards since AMD EOLed the old SoC they were
using. They seem to be going out of business, at least the low power x86
board business, so it's pretty much last time buys only now.

Shame. I finally got off my lazy ass during the pandemic and built a
home router exactly the way I like it, with an APU board.

That's the case with any component/assembly that is sourced outside of
your control; the more complex the assembly, the more dependencies you
incur.  *If* your supplier is willing to take on the task of ensuring
a "compatible" offering is continually available, then you're golden.
If not, you're at as much risk as they are.

If you want long term availability, SOMEONE has to pay for it (the days
of second, third, fourth, etc. sources are long past).  You can possibly
do a large "end-of-life buy" with scheduled delivery -- if your supplier
likes your credit and is happy with an unsecured commitment.

Or, you design YOUR device to be decoupled from the hardware as much as
possible.

[I don't bind a design to specific hardware until the design is complete
and running on some "development hardware".  Otherwise, there is a risk
that the available hardware will change (or morph to unobtainium) before
the design is finished and you play wack-a-mole for catch up.]

Pascal is pretty reasonable; I'm sure if you need a small quantity
he will try to oblige you.  Or, help you move to some other (possibly
competing) product.

Are any of these platforms any good to you?

There's a SBC page:
https://openwrt.org/toh/views/toh_single-board-computers
and some of those are SOMs.

Also searching 'openwrt som' turns up some products.

These are usually directly accessible on any platform with solid OpenWRT 
support - regardless of how esoteric the components are.

For the cheapest SOM's, look for Raspberry Pi compute modules.  If you 
want something very solid with good long-term support, industrial 
reliability and continued production for a decade or more, folks like 
Toradex are a good option - but they cost significantly more.

An alternative might be to view the Linux board more flexibly, and have 
your base board connected by USB.  Put a USB hub chip on it along with a 
couple of USB-Ethernet adaptors (combined devices exist, I believe), a 
USB 4G modem, and an FTDI 4232H or other FTDI chip (for UARTs and 
GPIOs).  Then you can use any board running Linux - all the hardware you 
need is on your board, and it is all controlled the same way from the 
Linux system.  USB2 based Ethernet is easily an order of magnitude 
faster than you need for VOIP, and none of this needs drivers or OS 
support outside of the standard kernel for the last decade or more.

Just got this in my inbox today - sorry, no english page:

https://www.openpr.de/news/1252910/TQ-praesentiert-neuen-Single-Board-Computer.html
https://www.youtube.com/watch?v=hr3-W0k_EhA

Manufacturer page:

https://www.tq-group.com/en/products/tq-embedded/arm-architecture/mba8mp-ras314/

They claim armbian support - that should work OK as a starting point, unless
you are fixed on OpenWRT.


Depending on volume, you might take one of their SOMs and put it on a custom
base board that adds power-over-ethernet and other add-ons as required.
