I want run linux embeded in this board. But in this process,there is not harddisk on the board. So I should mount the root fs on ramdisk. Do you think so? I should make a ramdisk. dd if=/dev/zero of=/dev/ram bs=1k count=2048 mke2fs -vm0 /dev/ram 2048 mount -t ext2 /dev/ram /mnt/ram ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ After I mount it, I should copy some files to this folder.I used cross_compiler, compiling linux on X86 PC.How do I make the file /sbin/init??where is the source?? dd if=/dev/ram bs=1k count=2048 | gzip -v9 > /tmp/ram_image.gz embedlf embedlf@citiz.net 2003-08-29
