Hi, Tony
I followed the instructions in the webpage that you provided.
Now, I can see the output file from the directory. However, when I tried to
read the file
(such as ls output_file), error was encountered: input/output error.
Steps done:
1. Modify fsconfig.py
#class CowIdeDisk(IdeDisk):
# image = CowDiskImage(child=RawDiskImage(read_only=False),
# read_only=False)
#
# def childImage(self, ci):
# self.image.child.image_file = ci
class RawIdeDisk(IdeDisk):
image = RawDiskImage(read_only=False)
def childImage(self, ci):
self.image.image_file = ci
Since I'm using Linux Alpha System, on the def makeLinuxAlphaSystem(mem_mode,
mdesc = None):
I changed the following codes
#self.disk0 = CowIdeDisk(driveID='master')
#self.disk2 = CowIdeDisk(driveID='master')
self.disk0 = RawIdeDisk(driveID='master')
self.disk2 = RawIdeDisk(driveID='master')
2. compile and install busybox, and execute busybox sync
Thanks!

Are you asking if it is possible to make changes to the file-system on the disk
image permanent? Yes, it is possible. You need to remove the copy-on-write
layer. I did this when developing the BBench-ICS disk image. Check out this

It seems that the output file in full system GEM5 is a ram file which will not
be written to linux.img.
Due to this, I cannot get the file after I exit gem5 simulation environment.
Thanks!
