Hi All.
Did anyone meet problem with mkefs at Windows Platform?
I use mkefs at host platform Windows 2000 (QNX Standart 6.2.1). I have some
problem:
- when total size of all files in filesystem is greather than about 4Mb
mkefs termintaed with exception. - I burn OS image and filesystem image (created by mkefs) into flash. I
join OS image & filesystem image with mkimage -b 8k -o cpu686.img
cpu686.flash fs
Where cpu686.flash = ipl+OS image, fs = filesystem image.
I clear the flash use flashctl -p /dev/fs0 -e
I put result file (cpu686.img) into flash use this command: cat
/tmp/cpu686.img > /dev/fs0
When total size of all files in filesystem image is about 260Kb all work
good. (I slay flash driver and start it again. I see /dev/fs0 /dev/fs0p0
/dev/fs0p0 /dev/fs0p1 /dev/fs0p2)
When total size of all files in filesystem image is about 1 Mb it does not
work. After stuff was burned into flash and flash driver was restarted I see
only /dev/fs0 /dev/fs0p0. No filesystem present
.
Some times ago I did this operations and has that problem, but “critical
size” was greather than now.
I use processors board cpu686e (Fastwell). There are 8Mb flash memory at
board. I use driver devf-cpu686e (created by SWD).
I think problem source is mkefs.
There output of mkimage for fs included small files(total size of all files
in filesystem is less than 1Mb):
C:\qnx\stuff\images\c686os>mkimage -b 8k -o cpu686.img cpu686.flash fs
NTO image – cpu686.flash @ 0
EFS image – fs @ 14e000
------ mkimage see that file “fs” is efs file
There output of mkimage for fs included files total size of all files in
filesystem is greather than 1Mb:
C:\qnx\stuff\images\c686os>mkimage -b 8k -o cpu686.img cpu686.flash fs
NTO image – cpu686.flash @ 0
NTO image – fs @ 14d2f0
----- mkimage doesnt see that file “fs” is efs file!!!
There are command file used by me for this work (it run at windows):
mkifs cpu686e-os.src cpu686os
mkefs fs.src fs
cat ipl-c686.rom cpu686os > cpu686.flash
mkimage -b 8k -o cpu686.img cpu686.flash fs
There are script file for building filesystem (fs.src):
[block_size=8k spare_blocks=10 min_size=2000k ]
#etc directory
[perms=755]/etc=./etc
[perms=755]/inetd=./inetd
[perms=755]/bin=./bin
When sting [perms=755]/bin=./bin is commented resulting filesystem image
work When this string uncommented resulting image doesnt work.
There are content of directories, referenced in fs.src:
