Dear all,
Could you please explain what happens exactly when Linux is booting from a
compact flash?
To my few knowledge, the Linux compressed image will be copied somewhere in
memory, will be uncompressed and the control will jump to the beginning
address of the Linux kernel.
Is there any boot loader that copies the Linux compressed image to the
memory?
Where in memory does it put the Linux kernel? For example, if I have 2 DDRs
in my hardware, in which of them it will be put the kernel?
Can I set the kernel location in memory manually?
Might be an stupid question but: Is it possible for the kernel to be half in
BRAMS and half in DDR?
Regards,
Moji

Yes there are several boot-loader for example U-Boot.

The kernel usually is copied at the start of the memory, so if you have
mapped the address 0x00000000 in the first bank, here will be copied it.
> Can I set the kernel location in memory manually?
Yes but usually it's not needed and you have to be carefully to modify it.
