Hi Vijay,
Thanks for your help! I created the ramdisk using the
following steps:
1. Recompiled the kernel to allow the ramdisk to be
greater than 4MB. Set it to 10MB instead.
2. dd if=/dev/zero of=/dev/ram bs=1k count=10240
3. mke2fs -vm0 /dev/ram 10240
4. mount -o loop -t ext2 ramdisk /mnt/new-ramdisk
5. mount -o loop -t ext2 ramdisk_old /mnt/old-ramdisk
6. copied all stuff from the old-ramdisk directory to
the new-ramdisk directory
7. umount /mnt/new-ramdisk
8. cat ramdisk | gzip -v9 > ramdisk.gz
However, after downloading the ramdisk to the Assabet
using angelboot, I got the following error messages
upon starting Minicom.
...
...
VFS: Mounted root (ext2 filesystem)
Freeing init memory: 64K
attempt to access beyond end of device
01:00: rw=0, want=8205, limit=8192

Here's the angelboot configuration i'm using:
base 0xc0008000
entry 0xc0008000
r0 0x00000000
r1 0x00000019
device /dev/ttyS0
options "9600 8N1"
baud 115200
otherfile ramdisk.gz
otherbase 0xc0800000
Any idea why I'm getting these errors? Would greatly
appreciate any comments/remarks!
Regards,
Supriyo
