- Subject: [ECOS] ecos ram filesystem
hello,
i am tyring to create an ecos image on a floppy (for
i386) that has
ramdisk file system support.
I included the packages: RAM filesystem and also the
FILE IO support in my
ecos image. However I dont know how to proceed
further.
I realize that you can create a ramdisk using a script
as follows:
@echo -- START --
dd if=/dev/zero of=rootfs.img bs=1k count=$1
/sbin/mkfs.minix -c rootfs.img
mount -o loop -t minix rootfs.img /mnt
cp -av rootdir/* /mnt
umount /mnt
gzip -9c rootfs.img > rootfs.gz
@echo -- DONE --
This is what I did: I booted the pc with redboot
floppy. I have simple 'hello world' application that
wants to read and write to a file. This app is
compiled into the ecos image. Then i load this ecos
image into memory and type 'go'. This just starts the
app and I cannot give any commands to ecos. (also i
havent been able to get my console working). The
printf statements just go to my pc monitor.
How do I tell ecos where my ramdisk is or how to mount
my image.
Any help would be greatly appreciated.
Thanks
Sagar
