Hey Folks,
I attempted to follow these instructions below, but I still can't get
a bootable card. I have a 2GB card that came with Eclipse, but I
really don't need it - just need to free up some space on the root
partition. In attempting to follow these steps, when I unzip (Step 5),
I get many "implausibly old time stamp" error messages before tar
exits in this fashion: "tar: Error exit delayed from previous errors"
Can anyone point me in the right direction? Thanks.
