[Nanopi M4: HTop recognizes all cores as little cores]

A deeper inspection shows, that it has something to do with the file /home/[username]/.config/htop/htoprc.

The config parameter "right_meters" is set incorrectly.

 

For my XU4 the proper params are:

right_meters=Hostname Tasks LoadAverage Uptime CpuFreq(1) CpuFreq(2) CpuFreq(3) CpuFreq(4) CpuFreq(5) CpuFreq(6) CpuFreq(7) CpuFreq(8)

 

HTOP shows the wrong labels when the params are:

right_meters=Hostname Tasks LoadAverage Uptime CpuFreq CpuFreq CpuFreq CpuFreq CpuFreq CpuFreq CpuFreq CpuFreq

[Nanopi M4: HTop recognizes all cores as little cores]

Have the same issue with my XU4.

 

I have a workaround for this. Remove all files in /home/[username]/.config/htop and replace it with the files from /root/.config/htop. 

Then all cores are labeled with "big." and ".LITTLE" as usual. But as soon as you change the configuration (for example toggle "Tree" with F5), everything is broken again.

 

[Which image should I install on Odroid U3 Community (exynos4412)]

Try it. I like Arch. They have also images for other boards.

Yes, I use it as headless machine.

If you like Arch Linux, this could be a thing for you:

[NanoPi Neo image - no boot partition]

Ok... it's alive. Seems that I only had trouble with ipv6. 

 

Thank you very much for your efforts and the great explanations. Now I know a bit more about the boot process at ARM Cores. 

[NanoPi Neo image - no boot partition]

Thank you, for your reply. Of cause Linux is able to read ext4. But I thought, that the first level bootloader of the H3 can't do that. All other ditributions I know are using a seperate fat partition for the bootloader.

Or is the bootloader located in raw format in front of the ext4 partition? This would explain all the free sectors in front of the ext4 partition.

 

Yes, I used Etcher. SD card is fine. At the moment I use the Linux distribution of FriedlyArm which is working fine on the same SD card (with a fat partition).

 

I will try to get the output of the serial console, so we can see what the bootloader is telling us...

[NanoPi Neo image - no boot partition]

If I open the image file for NanoPi NEO, I don't see the FAT32 boot partition.
