Flash From Network Yocto system
Flashing a complete Yocto system from Network using tftp & nfs
NOTE:
- Please make sure your host system is ready to use TFTP/NFS. Use our WIKI if required.
Build mininal file system
$ gedit ../sources/poky/meta/recipes-core/images/core-image-minimal-mtdutils.bb
Set the image to include:
IMAGE_INSTALL += "mtd-utils imx-kobs mtd-utils-ubifs"
Build the system:
$ bitbake core-image-minimal-mtdutils
Create a root file system and copy files
$ mkdir ~/flash_rootfs $ sudo tar xvf tmp/deploy/images/varsomimx6/core-image-minimal-mtdutils-varsomimx6.tar.bz2 -C ~/flash_rootfs $ sudo cp tmp/deploy/images/varsomimx6/uImage /tftpboot $ sudo cp tmp/deploy/images/varsomimx6/uImage-imx6dl-var-som.dtb /tftpboot/imx6dl-var-som.dtb $ sudo cp tmp/deploy/images/varsomimx6/uImage-imx6dl-var-som-solo.dtb /tftpboot/imx6dl-var-som-solo.dtb $ sudo cp tmp/deploy/images/varsomimx6/uImage-imx6q-var-som.dtb /tftpboot/imx6q-var-som.dtb
Insert nand-recovery into your host and copy files
$ sudo mkdir ~/flash_rootfs $ sudo cp -a /media/rootfs/opt/images ~/flash_rootfs/opt/ $ sudo cp /media/rootfs/sbin/nand-recovery.sh ~/flash_rootfs/sbin/
Boot into u-boot and change environment variables
$ setenv serverip <your host ip address> $ setenv bootfile uImage $ setenv nfsroot /ws/ron/yocto-dora-fsl-beta/rootfs_min $ setenv console ttymxc0 $ setenv bootcmd 'run netboot' $ boot
On the target flash your system:
$ nand-recovery.sh
a complete system is flashed into nand. Once the file system is built you can use it again and again to flash your VAR-SOM-MX6. You can update the images to use your images or custom nand-recovery.sh to your requirements.
