Hi All,
(1) I got few queries during the blank disk_image build using
util/mkblankimage.sh. The script asks for the size of the disk image
to be built in MB. Although my input size is 128MB, but the eventual
disk image it creates turns out to be of 7.9 GB. I tried out with
other input sizes (256, 512, 1024, 2048.... etc), but the everytime
the final disk image is of size 7.9GB. So is there any way so that I
can make the disk size as 2GB?
The command-line with the output are as follows:-
diba...@dibakar-desktop:~/m5-aab017d1adc6$ bash util/mkblankimage.sh
Do you have sudo access? [y/n] y
How large do you want this disk image (in MB): 128
util/mkblankimage.sh: line 101: let: crosstool-ng-1.7.1: syntax error:
invalid arithmetic operator (error token is ".7.1")
What directory would you like to build the image in? /home/dibakar
What would you like to name the image? x86root.img
dd'ing the blank image (this make take a while)...
Binding the image and partitioning...
Remounting image and formatting...
util/mkblankimage.sh: line 209: [: -eq: unary operator expected
Disk image creation complete.
-----------------------------------------
(2) Once I use that 7.9 GB disk Image for x86_FS run, I got the
following errors:-
command line: build/X86_FS_v1/m5.opt configs/example/fs.py

>From the script build/X86_FS/dev/disk_image.cc, it seems that the
panic is due to the these following set of lines in CowDiskImage::read
function:-
if (offset > size())
panic("access out of bounds");
Is this error showing due to this disk-image size? Have anyone faced
similar kind of problems during X86_FS run?
.
Thanks and Regards,
Dibakar
