Hello All,
In the ISAR framework,we ran the command to generate SDK
  *bitbake <image_name> -c populate_sdk*
There was an sdkchroot folder generated in tmp directory.
The instructions given in the readme of this folder tells us to use rootfs
of the target.
Should we specify the rootfs  folder of the generated image? If not Please
give us detailed instructions.

I have attached the readme file for  reference.
Thanks and Regards,
Rajashree Sankar

Building applications for targets in ISAR takes a lot of time as they are built under QEMU.
SDK helps to develop applications for target platform in crossbuild environment.

SDK contains cross-toolchain for target architecture and a copy of isar-apt repo with
locally prebuilt target debian packages.

 - First one have to mount the system directories for proper operation in chroot environement.
Just call supplied with sdk tarball  in  udo rootfs as an argument to the script `mount_chroot.sh`:

$ sudo mount_chroot.sh  <sdk_rootfs>

 - chroot to isar SDK rootfs:

$ sudo chroot <sdk_rootfs>

 - Check that cross toolchains are installed

:~# dpkg -l | grep crossbuild-essential-armhf
ii  crossbuild-essential-armhf           12.3                   all          Informational list of cross-build-essential packages

 - Install needed prebuilt target packages.

:~# apt-get update
:~# apt-get install libhello-dev:armhf

 - Check the contents of the installed target package

:~# dpkg -L libhello-dev

You get the SDK as tarball under build/tmp/deploy/images. This one can
be distributed, unpacked by the recipient, and its usage is then
documented in the contained readme. That can be considered to be a lot
like Yocto/Buildroot toolchains when using the relocate script. Note
that the latter feature was merged only last week, so you may want to
update your Isar version.
