Solving U-boot problem

[Thiago Radicchi Roque <trr@xxxxxxxxxxx>]

To change boot parameters in U-boot:

#setenv bootargs <bootparams>

To save the new parameters in flash:

#saveenv

For example, the kernel command line I use is this: "mem=32M console=tty0
console=ttyS0,115200 initrd=0x10800000,2M root=/dev/ram0 rw"

So, to set this, I use:

#setenv bootargs mem=32M console=tty0 console=ttyS0,115200
initrd=0x10800000,2M root=/dev/ram0 rw
#saveenv

To verify the list of parameters, type:

#printenv

To verify only the boot parameters, type:

#printenv bootargs

Hope this helps.

Hi, Russel,

How exactly does the bootloader take in the boot parameters.
Iam using uboot as the bootloader.
Is it through the  tagged list on the uboot side i.e the file
include/asm/setup.h which i need to modify.
 tried changing the order of the tagged list putting "ATAG_NONE"  at the
end of
the union .But  my uboot
dosent boot up in that case , i get a blank screen.

Regards,
MUNRO.
