[U-Boot-Users] Problem:'Kernel command line' not getting bootargs
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 jacky USISH RD CENTER

This is on PowerPC only.
But linux kernel boot information shows that the Kernel command line was empty, what may cause the problem.
A misconfigured or badly ported kernel.
