Nanopi M4V2 hangs (Solved)

[Lennyz1988]

Hi,

 

My Nanopi M4V2 often gets unresponsive. I cannot reach the nginx server when that happens. SSH also stops working.  The red led is on, and the green led stops blinking when it happens.

 

Any tips on what I can try?

 

Running:

Armbian buster with Linux 5.4.49-rockchip64 with heatsink from EMMC.

The legacy images are a lot more stable. I also often have crashes with mainline, and haven't figured out a reason why. Seems like multiple issue's to my guess.

I don't own a NanoPi M4, but based on my reading of the different forums could the information (CPU governor and frequencies) in this thread help?

Thank you for the hint. I lowered the CPU to 1.8 ghz maximum. I'll try if it makes any difference.

Also thank you for the tip. I'll try the legacy kernel if lowering the CPU speed doesn't make any difference. Am I going to miss certain function if I would switch to the legacy kernel?

There's no panfrost on legacy. But then again there's JMCC's media script for Bionic legacy.
I used to use the M4 at 2Ghz without any crashes on legacy kernel. I don't think that's the issue.
I've also tried lowering clock speeds but still had crashes with mainline. I was testing panfrost what makes things a bit more complicated.

sudo nano /etc/default/cpufrequtils 

ENABLE=true
MIN_SPEED=600000
MAX_SPEED=2016000
# performance i firefox preferences i 6 
# MAX_SPEED=1800000
#GOVERNOR=ondemand
GOVERNOR=performance

and firefox, Preferences, General, Performance, Use hardware acceleration when available, Content process limit 6

Just want to let you guys know that my Nanopi M4V2 runs smooth, cold and hangfree with the latest version. I accidently installed a mainline kernel instead of legacy, but haven't been having any problems since. I can't seem to download this version from the website (there latest is 5.10.12), but you can install this kernel with armbian-config.

 

Armbian 21.02.2 Buster with Linux 5.10.16-rockchip64

 

Great work guys!
