Mint 19.3 Linuxcnc Odroid H2+
Latency test does not exercise storage does it?
PS. I had to check but NVME is actually the M.2 interface.

Also it would be interesting to see what the differences are between the 3 storage options, SATA, eMMC and NVME.
Generally m.2 is considered the fastest.
If you read the docs regarding latency test, I'm not implying you haven't, it is mentioned to move files around, move windows and generally just "abuse" the computer.

What kind of storage are you using ?
I've added the following:
- Memory: i took the lowest timing modules on the approved memory( wiki.odroid.com/odroid-h2/hardware/ram#confirmed_ram_modules ) list i could find locally: Kingston (HyperX), 2x 16G (HX424S14IBK2/32 ) which is most likely way overkill size-wise, but whatever
- Storage: i had and "old" NVMe on the shelf: Samsung 960pro 1Tb
- Added wired network and installed the provided image on the NVMe, all tests were proformed while booting of the NVMe...
I had quite terrible results(like >4000us'ish max) untill i disabled EVERYTHING in the BIOS... as described in the various posts in this thread... + i disabled all powermanagement+screensaver in Mint aswell...then the results were stable... i forgot about the test running and came back after around 10.000sec and the results were identical to the one posted above... i did start 5 gears, but nothing "crazy" to shake it(i saw someone mention youtube etc)...

This was after an hour of running. I ran this after the above had run for 2:11.

I will post all of my bios setting later.
I also found it odd that when I ran the script to test latency I got far worse results. I am going to try that one more time without changing anything.
Edit to add BIOS setting used in test.

Nor will I be providing any further support.
For reasons that I do not and will not go into nor wish to discuss either privately or publicly.
The best bet would to be install Mint 20 & follow Tommy's instructions for installing Linuxcnc on Mint 20. The thread is under the "Installing Linuxcnc" section. Apart from the required NIC drivers there is nothing special about the Odroid, it is just a small form factor x86_64 PC platform. The Odroid wiki has information regarding NIC drivers. The official Odroid forum is another option for support regarding general installation of Operating systems.
This is all I have to say on the subject.

In that case it would be nice if you did a post on how to change the update packages to point to the correct place etc.
Thankyou.

I'm not married to mint, I had just seen that you had compiled the ISO that was all ready to go for this guy. I'm sure I'll be able to figure it out using Tommy's instructions.
