No documentation about how to flash the image from OpenEmbeded (Yocto)

I built an image for the poplar board with the layer meta-96boards and I ended with this products on the deploy dir:

$ ls -1sh tmp/deploy/images/poplar/

But there isn't any documentation about how to flash / boot this on the board.

Hi,

Sorry I only just saw this. Your right some documentation for OE should be added to this repo. In the meantime there is some docs sent with the original pull request to meta-96boards here 96boards/meta-96boards#154 (comment)

I recently worked with the Poplar board in Yocto/OE-core, and to flash the board I basically did the following,

git clone https://github.com/Linaro/poplar-tools && cd poplar-tools

DEPLOY_DIR="/${HOME}/src/yocto/build-rpb/tmp-rpb-glibc/deploy/images/poplar"

cp ${DEPLOY_DIR}/rpb-console-image-poplar.tar.xz .
cp ${DEPLOY_DIR}/fastboot.bin l-loader.bin
cp ${DEPLOY_DIR}/hi3798cv200-poplar.dtb .
cp ${DEPLOY_DIR}/Image .

bash ./poplar_recovery_builder.sh all \
            rpb-console-image-poplar.tar.xz

And then was simply to follow the instructions from the debian documentation,

https://github.com/96boards-poplar/Documentation/blob/master/debian/debian_build_instructions.md#step-7-copy-image-files-to-the-tftp-home-directory

I might create a pull-request when I get some downtime if someone does not beat me to it :).

I have also successfully built a wic image which can be flashed to the eMMC, this simplifies things a bit.
