My application is in aviation and I am very excited about this SBC. Here is what I like:
My App is like Google maps for pilots - used in cockpits - so thin profile and light weight is very important.
It runs on just regular 3Amp circuit - no heavy UPS required. Use any battery bank.
It has two wifi on boards – so one can be used to download things and one to serve as dedicated hotspot – very useful.
Its sufficiently fast - scored 110 on Jetstream 2.1 but Geekbench crashes.
UFS storage - fast and no issues with being corrupted by power loss so far.
Has four USB - I need them all.
Dimensions are perfect - just over 70mm wide.
Issues:
Odd mounting hole location. Only two holes line up with HD8 display or any other RPI form compatible display Not compatible with Radxa HD8 dispay: Cable that comes with HD8 does not reach the MIPI port on the SBC Poor OS Support so far I got Ubuntu working but had many issues which I will list separately
Overall very promising. I hope we get Radxa OS or Debian 12 derived system to fully exploit this board Look forward to hearing from others
First I am seeing this PCI error when a plug in a particular USB module (a SDR Radio) and run a specific software (Stratux). USB module works fine until I run stratux. SO ts a combination of USB dongle, software and OS/hardware.
How do I go about fixing this?

2nd issue is that if you upgrade all packages you end up a broken GTK/GNome and all tools/widget stop working. Again I think we are using an old OS with old kernel - thats the issues.
Error is below and there is no fix/workaround for this
$ gnone-control-center

I installed the downloaded version from your site. b7 - build 7 I guess.
This week I was able to do dist upgrade ro Ubuntu 24.04 and I my GNOME and everything else kept working.
My only outstanding issue from what I have posted here is that Geekbench 6.2.2 does not finish (quits near the end). But most importantly when I use one piece of software that reads USB dongle (a software define radio module) entire system freezes. This does not happen on any other board so I suspect something is off with your USB hardware or you will need a fix in Linux Kernel for whatever you are using or I need to find what is in this Radio tuner software that is causing this.
Other than I am very happy with this board - there is nothing else like this. It has at least 30% less power consumption than Raspberry PI - this makes a huge difference for my project. Not to speak of so many ports and possibilities in a 9mm thin package - unbelievable! Please keep up the good work!
Any idea what do about USB 3.0 port issues? I get these errors when connecting any USB device to USB3.0 ports (and only after I have installed a particular Radio tuner). When I connect the same USB devices to a hub attached to USB 3.0 OTG port - they work fine.
No I am not using Ubuntu 24 at this time, I tried once to see if my USB PCIe errors would go away but it did not . So I am at b7. Yes there is a b7 Pl. see your download page: https://dl.radxa.com/nio12l/images/ubuntu/
Since I was getting frustrated with your Ubuntu support I tried Android - which had a more recent update (Sept 12) and I was pleasantly surprised:
Geekbench passed with respectable score (Single Core: 955, Multi: 2300)
Power consumption is 20% less than Linux/Ubuntu - with all USB slots in Use I drawe 12-13 watts which is within limit of 15Watts UPS I am using)
But even here there are many challenges:
Wifi not available - you have two Wifi Chips yet Wifi does not work. Only Ethernet works.
General questions (about both Ubuntu/Android):
Is there is. possibility of external power button? I see there is 2-PIN a header next to power button - I soldered two pins and connected to a Momentary switch - but it did nothing (in either Android or Ubuntu). Do I have to write some wrapper for this?
Where is documentation on how to use GPIO pins (in either Ubuntu or Android)?
While I like the promise of this board - you really have to improve documentation and software.
I figured why I was getting PCIe USB errors - too many crazy unnecessary udev rules in a third party software I was using. So I am back to Ubuntu where all my software now works - because USB works hang free.
regarding header for power off/on button - I am not able to figure out what those two header/pins by power button are for and what GPIO they correspond to.
But there is post on how to make system boot automatically when plugging in USB-C power. So I am using that (connect download USB-C to screen). Until i figure how to get a power on/off header - I connected Pin 14 (GND) and PIN 16 (GPIO61 - DMIC1_SLK) to a momentary switch and I am able to use command like
I sure hope Radxa will provide more information for GPIO programming - for example how do I convert Rx/Tx pins into a serial line? etc.
Detail of eternal power switch header would be useful. External power button switch is a must for us.
It would be helpful to get Ubuntu 24 support - fo newer kernel and newer software
Unclear how to scale building your own system around this board - how to flash at scale, how to control disk partitions - have your own partition scheme etc.
