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 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/imx6ul-var-dart/core-image-minimal-mtdutils-imx6ul-var-dart.tar.bz2 -C ~/flash_rootfs Linux: $ sudo cp tmp/deploy/images/imx6ul-var-dart/zImage /tftpboot Device Tree: $ sudo cp tmp/deploy/images/imx6ul-var-dart/zImage-imx6ul-var-dart-emmc_wifi.dtb /tftpboot/imx6ul-var-dart-emmc_wifi.dtb $ sudo cp tmp/deploy/images/imx6ul-var-dart/zImage-imx6ul-var-dart-nand_wifi.dtb /tftpboot/imx6ul-var-dart-nand_wifi.dtb $ sudo cp tmp/deploy/images/imx6ul-var-dart/zImage-imx6ul-var-dart-sd_emmc.dtb /tftpboot/imx6ul-var-dart-sd_emmc.dtb $ sudo cp tmp/deploy/images/imx6ul-var-dart/zImage-imx6ul-var-dart-sd_nand.dtb /tftpboot/imx6ul-var-dart-sd_nand.dtb
Insert nand-recovery into your host and copy files
$ sudo cp -a /media/rootfs/opt/images ~/flash_rootfs/opt/ $ sudo cp /media/rootfs/sbin/*.sh ~/flash_rootfs/sbin/
Boot into u-boot and change environment variables
Select one: $ setenv fdt_file imx6ul-var-dart-nand_wifi.dtb $ setenv fdt_file imx6ul-var-dart-emmc_wifi.dtb $ setenv fdt_file dts/imx6ul-var-dart-sd_nand.dtb $ setenv fdt_file dts/imx6ul-var-dart-sd_emmc.dtb $ setenv serverip 192.168.1.38 $ setenv image zImage $ setenv nfsroot /home/<your username>/flash_rootfs $ setenv console ttymxc0 $ setenv bootcmd 'run netboot' $ saveenv $ boot
On the target flash your system:
$ yocto-nand.sh $ yocto-emmc.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.
