Yocto QEMU UNFS test procedure

Steps to run the NFS test case for all qemu machines

Prerequisites:

1. Have a clone of poky

$ git clone git://git.yoctoproject.org/poky

2. Checkout the correct hash.

$ git checkout    and/or   $ git log

3. Download the "kernel" file (<ZIMAGE>.bin) and the image compressed file (<IMAGE NAME>.tar.bz2) from autobilder link.

Steps:

1. Open a terminal and place in poky/ directory.

$ cd $PATH/poky

2. Source the environment:

$ source oe-init-build-env build

4. Place the downloaded kernel (<ZIMAGE>.bin) and the <IMAGE NAME>.tar.bz2 file after "build" directory, something like "/home/<YOURUSER>/poky/build/tmp/deploy/images/qemu<MACHINE>/"

Note 1: First you need to create manually those directories in your system. a) In poky directory create tmp directory (~/poky/build$ mkdir tmp); b) Then access to tpm ($ cd tmp ); c) Create deploy directory ($ mkdir deploy ); d) Access to deploy directory ($ cd deploy ); e) Create images directory ($ mkdir images ); f) Access to images directory ( $ cd images ); g) create your qemu folder, for example if you are testing qemux86 ($ mkdir qemux86 ); h) Access your qemu folder, for instance to qemux86 directory ( $ cd qemux86 )

Note 2: you can avoid to download and copy here the files and directly download in this path, typing in this path the following command:

$ wget /<WEB_ADRESS_OF_THE_KERNEL_IMAGE>/<ZIMAGE>.bin

$ wget /<WEB_ADRESS_OF_THE_IMAGE>/<IMAGE NAME>.tar.bz2 

5. Go to build directory:

$ cd /home/<YOURUSER>/poky/build

6. Extract the SDK, typing in a terminal the following command:

$ runqemu-extract-sdk tpm/deploy/images/qemux<MACHINE>/<IMAGE NAME>.tar.bz2 rootfs

Note 3: "rootfs" is referring to a directory going to be created, you can choose any name as you want.

Note 4: is it possible that the system will ask you to bitbake the system first. If so, then type in the terminal $ bitbake meta-ide-support (This process would take a while). Then type again in a terminal: $ runqemu-extract-sdk tpm/deploy/images/qemux<MACHINE>/<IMAGE NAME>.tar.bz2 rootfs

7. Start the qemu machine with NFS:

$ runqemu nfs tmp/deploy/images/qemux<MACHINE>/<ZIMAGE>.bin/ rootfs

qemu machine should be launch after this command.

8. Finally, from qemu open a terminal type

$ poweroff

to exit.
