Flashing a complete Yocto system from Network using tftp & nfs
- 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 Trees: $ sudo cp tmp/deploy/images/imx6ul-var-dart/zImage-imx*.dtb /tftpboot/ $ sudo rename 's/zImage-//' /tftpboot/zImage-*
Insert the recovery SD card into your host PC and copy the following files from it (assuming it is mounted at /media):
$ 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:
Select one: => setenv fdt_file imx6ul-var-dart-nand_wifi.dtb => setenv fdt_file imx6ul-var-dart-emmc_wifi.dtb => setenv fdt_file imx6ul-var-dart-sd_nand.dtb => setenv fdt_file imx6ul-var-dart-sd_emmc.dtb => setenv fdt_file imx6ull-var-dart-nand_wifi.dtb => setenv fdt_file imx6ull-var-dart-emmc_wifi.dtb => setenv fdt_file imx6ull-var-dart-sd_nand.dtb => setenv fdt_file imx6ull-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
TFTP & NFS detail
On the target flash your system:
$ install_yocto.sh
A complete system is flashed into the SOMs internal storage (NAND flash/eMMC).
Once the file system is built you can use it again and again to flash your DART-6UL.
You can update the images to use your own images or customize the install_yocto.sh script to your requirements.
