actually I have 960MHz configured in cpufrequtils. Is it safe/stable to use 1000 MHz, or will that value already lead the ct to crash?

960mhz vs 1000mhz is almost same, i dont think you will notice difference.

Hey folks,

I'm experiencing the same problem running CTDebian2.4 with 3.4.98-sun7i+. It looks like downloads from cubie breaks earlier and more often than uploads to it.

I already tried different switches/routers, cables, PSUs, other kernels and distributions, underclocking etc. - but nothing make any difference :(

Of course I did multiple times. Is the problem finally solved? Did I overlooked something?

He?  ::)

I also tried different .fex-files.

My current workaround solution is to use a 100mbit USB NIC. It works like charm but is not as fast as the Gbit NIC.

I had the exact same problem. Tried different images, u-boot, kernels... One image did work though - lubuntu nand.

Observing it's script.bin, I did read that max_freq was set to 1008000000 in this distro, while it's usually set to 912000000.

Code: [Select]
< max_freq = 1008000000
---
> max_freq = 912000000

I did the change (bin2fex script.bin > script.fex / edit script.fex, change the value, save / fex2bin script.fex > script.bin) and right now the network is working like a charm.

Worth a try!

I spend several days trying all solutions until I found this one.

Hope it helps!

Well, maybe different people can have a different problem and the cpufreq trick didn't work for 'em?

Cheers

Sloop means that the other people have solved this problem ages ago and you are now re-discovering exactly the same solution :)

I did guess so too, but I didn't found this solution on this thread (cpufreq & voltage only).

Did just want to share in case it helped as this seems to be a recuring problem many people have. Good luck everyone!

(Edit: doesn't work for me in all cases though - even a 'perfect' (as defined in this thread) .bin script + correct cpufrequtils can let me have network issues with some distributions)
