2. When the root file system has been stored in NAND Flash it is time to load and boot the Linux
kernel. A variable named
mtdboot
is available in the default environment. This variable will
setup the boot arguments to use a root file system in NAND flash (in an MTD partition), load
the kernel and then boot it. The content of the
mtdboot
variable is explained in section
4.3.5. Run the command:
uboot> run mtdboot
3. There will be a lot of output in the terminal application when the kernel boots. Only a portion
has been included below.
