I ordered the 2 GB Pine64 64 bit ARM board. It’s extremely constrained compared to the normal 64 bit ARM boards I use, but it’s good that there’s one which may be supported by upstream Linux in the near future.
Total cost for the board + the wifi accessory + postage to the UK is $50.98 (£42.36).
Let’s see how it goes …
They also have this strange SO-DIMM form-factor co-processor. I’m not sure what to make of it.
Gigabyte just announced a bunch of full ARM servers, with between 32 and 96 cores. They are based around the Cavium ThunderX processors that we’ve had at Red Hat for a while so they should run RHEL either out of the box or very soon after release.
The data sheet is here but in brief, quad core AMD Seattle with 8 GB of RAM (expandable to 64 GB). Approximately equivalent to the still missing AMD Cello developer board.
For everyone who has ever used what I call junk ARM dev boards, and hasn’t been able to work out what combination of out-of-tree u-boot/kernel patches they should be using, or how to enable the serial port, Jon is trying to make the situation better on 64 bit ARM server hardware. Needless to say, I very much approve. Here is his talk:
I finally got UEFI flashed onto the Gigabyte board so now it is SBSA/SBBR compliant [edit: see note at end] and will just work with RHEL. Instructions here: https://lists.centos.org/pipermail/arm-dev/2016-March/001743.html
Here are the boot messages from TianoCore:
TianoCore 1.20.03 UEFI 2.4.0 Jan 26 2016 18:09:04
CPU: APM ARM 64-bit Potenza Rev B0 2400MHz PCP 2400MHz
32 KB ICACHE, 32 KB DCACHE
SOC 2000MHz IOBAXI 400MHz AXI 250MHz AHB 200MHz GFC 125MHz

The default boot selection will start in 1 second
Note: A few people have pointed out that the Gigabyte isn’t SBSA compliant because it lacks the right serial port, RTC and WDT. However it still boots RHELSA fine if you add
IPMI works out of the box. I’m using FreeIPMI to test this (not ipmitool) since FreeIPMI is a lot easier to use.
You need to know that:
- The default user name is
admin and the default password is
- You have to use the dedicated management interface, marked “f” in the software reference guide (the ethernet port above the two USB sockets).
Here are the sensors:

Firstly Jon Masters demonstrates running RHEL 7.2 with a (very very nearly) unmodified upstream kernel on SBSA/SBBR standards supporting hardware:
Secondly the LeMaker Cello is available for preorder from http://www.lenovator.com/product/103.html with delivery next month.
