[U-Boot-Users] Passing Parameters to kernel
Hi,
How do i ensure the ATAG parameters are getting passed properly from U-boot to Kernel.
The bootargs command line that i specify in U-boot is not what i see on kernel command line.
The bootargs from U-boot gets overwritten by the default kernel command line specified in kernel configuration.
What could be the cause? How do i overcome this.
Eagerly awaiting your reply.

Check if you have
CONFIG_CMDLINE_BOOL
set in your .config. If so, unset it.

Which kernel and which gcc do you use? If you use a 2.4 kernel with gcc 3.4, you'll see exactly these problems.
