For devices that are deployed for some purpose, to work without frequent manual intervention, the question is when would you charge the battery? Either you can keep the charger connected - which may possibly swell the battery soon, unless the device has some way to auto-stop charging at some upper threshold and auto-restart the charging only when the battery reaches a lower threshold. Or you may have to intervene manually to connect / disconnect the charger (like a mobile phone). -- Mayuresh

We create SD card images for you: armbsd.org. Just copy the proper image to the sd card and you should be ready to boot. Martin

NetBSD runs fine on A20. You can look at http://wiki.netbsd.org/ports/evbarm/allwinner/ for details on creating a bootable SD card > o can I hook up a serial concole via a standard RS232 cable? No, most SBC use a serial port with TTL levels (usually 0 and +3.3V), not RS232 levels. You need a USB-UART adapter like FTDI-based one, or this one: https://www.olimex.com/Products/Breadboarding/BB-CH340T/open-source-hardware > o after the initial install of NetBSD, can I have the computer boot > from a USB (preferably C-type, but standard type okay)?

Note that the A20 has a native SATA port (i.e. not behind a USB-SATA bridge), so if you need speed or capacity, adding a SATA 2.5" disk or SSD is a good option (I run one with a SSD too). > o is there a cookbook-kind of howto document on installing NetBSD on > ARM architecture SBCs?

Re: Which ARM SBC would work well with NetBSD?
I've been listening in, and I thank you all very much for your input. I have 0 experience with an SBC, but want to move to a low-power-consumption basic web and file server. Because of the battery options which would allow me to do without a UPS, I'm seriously considering the olimex a20-onlinuxino-lime2. Some questions from this newbie: o can I create a NetBSD bootable micro SD card, or does one have to use Debian or Android on these A-20 Olimex SBCs? o can I hook up a serial concole via a standard RS232 cable? o after the initial install of NetBSD, can I have the computer boot from a USB (preferably C-type, but standard type okay)? Or is it better to just get a board with the eMMC flash memory option and boot from that? o is there a cookbook-kind of howto document on installing NetBSD on ARM architecture SBCs?

I run a Quartz64 Model B in production (using netbsd-10). It is great, only downside is that the hardware forces you to choose between xhci (USB 3) and the on board SATA connector - and unfortunately the firmware used to boot NetBSD only supports xhci currently.

Please do share. I highly recommend the Pine64 devices. I have an A64-LTS, which has been rock-solid. The RockPro64 is the one with the highest performance. All of these are well-supported by NetBSD.

I'm very happy running a RockPro 64 on -current. It's not great on NetBSD 9, but you can just run a NetBSD 10 or -current kernel and it will just work great. Great performance, no blobs, rock solid and stable. I use it as my production server and have had 0 issues. -- Jonathan
