Again, thanks for your fast response!

Now I know what I should look for.

Yes, exactly. These are the spacers, the page also has better dimensions. The BOX-AGONLIGHT2-BLACK kit should include 4 of those. But maybe first check for similar spacer in a general hardware shop around you to save on the shipping.

Thank you for the fast response!

Then, I should understand that will work the hexagonal spacers which can be ordered from the link bellow?

https://www.olimex.com/Products/Components/Fasteners/HEX-SPACER-M3X6/

With the case arrived 8 screws, which I think they are all needed.

Sorry for this, it is rare for the guys in the packing to miss components during packing.

These are metallic M3x6mm female-female hexagonal stand-offs. Refer to the picture on how they look:



The screws that are used for them are DIN7985 M3x4mm

AgonLight / What kind of hexagonal spacers...
Last post by Adrian.VT - October 28, 2024, 10:26:25 AM
I have ordered an AgonLight2 board and its case, but unfortunately the case arrived without the 4 hexagonal spacers which I suppose that should be shipped along, then I am unable to mount the board in its case.

I am quite disappointed that the case arrived without all accessories, BUT I did not made this post just to lament - I opened it to try to find a way to get these missing hexagonal spacers.

So, my question is what kind of hexagonal spacers are used in this case, and if I can order them separately.

Eventually, just their exact dimensions can be useful for me.

A20 / Re: Ethernet problem A20-OLinu...
Last post by LubOlimex - October 28, 2024, 08:19:38 AM
Each board gets a network throughput test after manufacturing, each board is required to have at least 300Mbit/s throughput.

Are you testing with Olimage Linux? If not, please test with Olimage and report back. Refer to this document:

A20 / Ethernet problem A20-OLinuXino...
Last post by valt - October 26, 2024, 06:57:19 PM
Hello everyone,

I've owned an Olimex A20 Lime2 Rev.K for a few months and a problem related to the ethernet remains unresolved despite my numerous searches on the Internet and various forums. My box is connected directly via an ethernet cable to my ISP's box. Trying to use this famous ethernet cable from my personal PC, a speed test gives me a downstream speed of around ~900 Mbps. However, when I connect this cable to my olimex, the speed suddenly becomes very low, trying an iperf on a public server with a speed of 100 Gbit/s I get about 30 Mbps:
root@olimex:~# iperf3 -c ping.online.net

However, if I look at my network card, I'm supposed to be able to receive at least 1000 Mbp/s :

Do you know of a similar problem with anyone else? Do you have any advice on how to fix it?

STMP1 / Re: Hardware acceleration, GPU
Last post by jalih - October 25, 2024, 11:33:34 AM
Okay, kms/drm and hardware acceleration works nicely!

It's a really nice hardware for home automation central control. I should soon have my software (sorry about the background noise in video) written in 8th programming language up and running.

New Product Ideas / Re: Arm SystemReady Compliance
Last post by LubOlimex - October 25, 2024, 11:04:37 AM
We have no such plans at the moment. No. But we might consider it in future.

All sources for our Linux images are published at GitHub and available for anyone to see (you don't even need a purchase to study our Olimage images). Nothing shady or hidden. Differences with original source are easy to spot since we have only two developers that commit in these repos. I recommend you to check this document on Olimage images:

New Product Ideas / Arm SystemReady Compliance
Last post by f.k. - October 25, 2024, 10:06:35 AM
Hello,

we like the olimex hardware but we don't like that there are custom linux images for the various boards with custom kernels, etc. we would prefere to be able to use standard unmodified mainline linux kernels (e.g. debian distribution) to make sure there are quick fixes for security issues, etc. available.

For ARM servers the Arm SystemReady standard (https://www.arm.com/architecture/system-architectures/systemready-certification-program) is very popular to standardize the boot process/interface. It's also available for general embedded devices.

Are there any plans to make some boards compliant to the Arm SystemReady standard?
