Hi All,
I am trying to bring linux from RAM. I have compiled the kernel and created
uImage. I bring the image over tftp into the memory and then execute bootm
memaddress. Unfortunately here is the output from my command line:
tftp 0x8000 ipaddress:uImage
Using egiga0 device
TFTP from server ipaddress; our IP address is ipaddress; sending through
gateway ipaddress
Filename 'uImage'.
Load address: 0x8000

Now, the image is good for sure because I do not have issues bringing this
image from the hard drive. Do I need anything else (ftd or ramdisc) to boot
from RAM or the procedure presented is correct?
my bootargs are:
bootargs=console ttyS0,115200 root /dev/ram rw
Thank you for your help,
Ogi
