hatahata 
Hi all .

root@NanoPi3:/home/fa# touch /SWAP

root@NanoPi3:/home/fa# dd if=/dev/zero of=/SWAP bs=1M count=128
128+0 records in
128+0 records out
134217728 bytes (134 MB) copied, 23.1655 s, 5.8 MB/s

root@NanoPi3:/home/fa# mkswap /SWAP
Setting up swapspace version 1, size = 131068 KiB
no label, UUID=15a0107d-f2a1-4ecd-ad91-8a76e7e92e4c

root@NanoPi3:/home/fa# swapon /SWAP
swapon: /SWAP: swapon failed: Function not implemented


how to conquer ' swapon failed: Function not implemented ' ?

from http://forum.odroid.com/viewtopic.php?f=22&t=871

Beat me to it.

Have a look for sway on this forum:

http://billforums.station51.net/

davef 
sway = swap

hatahata 
thanks for advice .

but i cannot find sway in http://billforums.station51.net/.


---------
i follow
http://wiki.friendlyarm.com/wiki/index.php/NanoPi_M3#Compile_Linux_Kernel.

and 

after make menuconfig,

fa@NanoPi3:~/Kernel/linux-3.4.y$ diff .config .config-ori
53c53
< CONFIG_SWAP=y
---
> # CONFIG_SWAP is not set
96d95
< # CONFIG_CGROUP_MEM_RES_CTLR_SWAP is not set


by
wget -c
http://www.dragonwake.com/download/arm9-download/linux-toolchain/arm-lin...

but i cannot prepare to use arm-linux-gcc .

how to prepare arm-linux-gcc ?

davef 
You need to download the toolchain on the FriendlyArm wiki for their
product.

hatahata 
where can i get toolchain ?

hatahata 
acoording your advice ,
i found https://github.com/friendlyarm/prebuilts/tree/master/gcc .

and
follow 
http://wiki.friendlyarm.com/wiki/index.php/How_to_build_the_Compiling_En...

but


fa@NanoPi3:~$ echo $PATH
/opt/FriendlyARM/toolschain/4.4.3/bin:/usr/local/bin:/usr/bin:/bin:/usr/local/ga
mes:/usr/games:

but
fa@NanoPi3:~$ arm-linux-gcc -v
/opt/FriendlyARM/toolschain/4.4.3/bin/.arm-none-linux-gnueabi-gcc: 1:
/opt/FriendlyARM/toolschain/4.4.3/bin/.arm-none-linux-gnueabi-gcc: Syntax
error: "(" unexpected

how to cope with this ?

---
regards

hatahata 
i may download the wrong file .
it is hard to download arm-linux-gcc-4.4.3.tar.gz of friendlyarm .
i must do some effort .

davef 
Syntax error: "(" unexpected


Seen that mentioned before, search the specific error message.

Does the M3 require a 64 bit development environment?

hatahata 
i did
git clone https://github.com/friendlyarm/prebuilts.git

now

md5sum arm-linux-gcc-4.4.3.tar.gz 
1be8415ee80ba0746baedce41a4b04ba  arm-linux-gcc-4.4.3.tar.gz

and 
ls /opt/FriendlyARM/toolschain/4.4.3/
arm-none-linux-gnueabi  bin  include  lib  libexec  share

and 
echo $PATH
/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games:/opt/FriendlyARM/toolsc
hain/4.4.3/bin


arm-linux-gcc -v
/opt/FriendlyARM/toolschain/4.4.3/bin/.arm-none-linux-gnueabi-gcc: 1:
/opt/FriendlyARM/toolschain/4.4.3/bin/.arm-none-linux-gnueabi-gcc: Syntax
error: "(" unexpected


too hard !
i give up .

davef 
Well, it might help if you answered my question.

You are running on a 64bit platform?

Also, why 4.4.3, when according to the wiki page you need 4.9.3

hatahata 
default nano pi M3 , perhaps 64 bit .

i follow
http://wiki.friendlyarm.com/wiki/index.php/NanoPi_M3#Install_Cross_Compiler


but but
arm-linux-gcc -v

-bash: /opt/FriendlyARM/toolchain/4.9.3/bin/arm-linux-gcc: cannot execute
binary file: Exec format error

this is also hard wall to climb .

hatahata 
i make mistakes .
this is a cross compiler !

i did i on debiandog 64 linux .

---
 Download the compiler package:

git clone https://github.com/friendlyarm/prebuilts.git
sudo mkdir -p /opt/FriendlyARM/toolchain
sudo tar xf prebuilts/gcc-x64/arm-cortexa9-linux-gnueabihf-4.9.3.tar.xz -C
/opt/FriendlyARM/toolchain/

Then add the compiler's directory to "PATH" by appending the following
lines in "~/.bashrc":

export PATH=/opt/FriendlyARM/toolchain/4.9.3/bin:$PATH
export GCC_COLORS=auto

Execute "~/.bashrc" to make the changes take effect. Note that there is a
space after the first ".":

. ~/.bashrc

1.The following commands can create a 128MB file to be for virtual memory
(swap)&#65292;of courses&#65292;you can modify the first command to change
size yourself.

dd if=/dev/zero of=/var/swapfile bs=1M count=128
chmod 0600 /var/swapfile
mkswap /var/swapfile
swapon -f /var/swapfile

2. You need to compile kernel to open swap partition&#65292;after using
supports open swap partition kernel to instead of old kernel that you can
excuse the above commands.
