Flash From Network Yocto system
Flashing a complete Yocto system from Network using TFTP & NFS
NOTES:
- Please make sure your host system is ready to use TFTP/NFS. Use our WIKI if required: TFTP & NFS
- Mix and match the nand-recovery version with the system you would like to flash.
- This is a concept Wiki. Please adopt it to your system and your requirements.
- Android can be flashed in the same way.
Build minimal 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/var-som-mx6/core-image-minimal-mtdutils-var-som-mx6.tar.bz2 -C ~/flash_rootfs $ sudo cp tmp/deploy/images/var-som-mx6/uImage /tftpboot $ sudo cp tmp/deploy/images/var-som-mx6/uImage-imx*.dtb /tftpboot/ $ sudo rename 's/uImage-//' /tftpboot/uImage-*
Insert the recovery SD card into your host PC and copy the following files from it (assuming it is mounted at /media):
$ sudo mkdir ~/flash_rootfs $ sudo cp -a /media/rootfs/opt/images ~/flash_rootfs/opt/ $ sudo cp /media/rootfs/usr/bin/*.sh ~/flash_rootfs/usr/bin
Boot the board, stop the autoboot to get to the U-Boot command line, and set the following environment variables:
=> setenv serverip <your host ip address> => setenv bootfile uImage => setenv nfsroot /home/<your username>/flash_rootfs => setenv console ttymxc0 => setenv bootcmd 'run netboot' => boot
On the target flash your system:
$ install_yocto.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.
