[U-Boot-Users] Problem:'Kernel command line' not getting bootargs

27 Jun 2006


      Hello:
When implement bootm command, u-boot will start linux kernel, and pass the
parameters with r3, r4, r5, r6 and r7 like this.
/*
     * Linux Kernel Parameters:
     *   r3: ptr to board info data
     *   r4: initrd_start or 0 if no initrd
     *   r5: initrd_end - unused if r4 is 0
     *   r6: Start of command line string
     *   r7: End   of command line string
     */
    (*kernel) (kbd, initrd_start, initrd_end, cmd_start, cmd_end);
But linux kernel boot information shows that the Kernel command line was
empty, what may cause the problem.
Thank you!
 Best wishes
