Hi, I´m using the last armbian image () and I see that the system is using Memory usage:  9 % of 844MB , when the device has 2gb of ram. How can I make the system use the full memory for the nanopik2 ?

 

Thanks in advance.

If you can compile it yourself I have that fixed in the build system, it was a u-boot issue. 

 

[edit to clarify the brief answer]

This board was moved from a "wip" (work-in-progress) to a "csc" designation, meaning community support only, it is not a future target for Armbian.  This is due to a combination of factors including manpower and general community interest.

That´s a pity. 

Anyway... I´m having another issue. I installed transmissionbt and I have a 1tb WD connected to download torrents (ext4). I was using with libreelec without any kind of issues, but when I change to this distro, and the download speed go over 1mb the system crash and I need to reboot manually disconnecting the power.  As I say before, I was downloading at 20mb with libre elec without issues, but now, I can´t. 

 

Any advice?

Thanks

The support for this was never more than experimental, so I wouldn't be surprised to find more bugs.  The only reason it got as much support as it has is because it is based on the same family SoC as the Odroid C2 and Le Potato.

 

Can you give me the name of the image file you used?  That sounds related to the memory mapping bug that should have been fixed https://github.com/armbian/build/blob/master/patch/kernel/meson64-next/1020_GXBB_memory_allocation_meson_GX.patch

 

This should be the newest download, and should be clean/as up to date as possible: https://dl.armbian.com/nanopik2/Ubuntu_xenial_next_desktop.7z

 

That's a 4.14.15 from January with all known bugfixes.

I am interested in the K2 board but I need AES support for my use case. Could you please run the following command and post the result?

"openssl speed -elapsed -evp aes-256-cbc"

@nanopik2:~$ openssl speed -elapsed -evp aes-256-cbc

With Hardkernel's bootloader blobs it should be possible to let the S905 run with 1.7GHz and then numbers slightly improve. But the results were already known before since SoCs matter and not boards (see ODROID-C2 numbers, as expected: same S905, same performance at same clockspeed with same memory configuration -- yeah, the latter is where boards might make a small difference :) )
