[ts-7000] Booting to SD: How do I find the "ramdisk_address" and "ramdisk_length" ???

["roquesolis66" <>]

Hi,

I just got a 7260 board and I need to boot it from an SD card.  I have an 
application and 
linux built already which I use on the 7250 and I can boot from CF card on that 
one with 
no problem.  It turns out that the 7260 cannot boot directly from the SD card 
unless it 
goes through a ramdisk "initrd".  

I am trying to follow the instructions in the Technologic Sysems Wikki, which 
tell me to 
use the 'exec' command in this manner:

------------
  1.) Load an initial ramdisk from flash.
     fis load initrd
  2.) Load a kernel from flash.
     fis load vmlinux
  3.) Execute a kernel
     exec -r 0x00600000 -s ramdisklength -b 0x00218000 -l loadlength -c 
"console=ttyAM0,115200 root=/dev/ram0 init=/linuxrc rw"

------------

I have downloaded a pre-built ramdisk from the Wikki but i have no idea what 
values to 
use for the "-s", "-b", and "-l" parameters.  

Like I said, I have a CF card image which I just copied to the SD card and I'm 
trying to boot 
from that.  I appreciate any help.

Thanks,

Roque
