Hello, It works !!
Thanks you very much !! Best regards, Mickael. PS : I just change a line .long __bss_start @ r6 by .long _edata @ r6 if fact, like in 2.4.x kernel with CONFIG_RAM_ATTACHED_ROMFS switch. 2007/4/19, Lance Spaulding <[EMAIL PROTECTED]>:

I've attached a small patch of the changes I made to get this to work. Note that we use little-endian exclusively so if you are using big-endian you will need to change the code slightly.
