I have installed Momentics 6.2.1b on both Windows and QNX hosts. Using mkefs
on a same build file gives different output. Heres the session on Windows:
$ mkefs p1.build p1-default.bin
$ dump p1-default.bin | head -n10
p1-default.bin:

And here’s the same on QNX:
mkefs p1.build p1-default.bin
hd -n64 p1-default.bin
0000000 83 ff 14 00 4c 00 01 00 11 00 ff ff 00 00 00 00 …L…

0000041
The program seems to default to different filesystems (ffs3 on windows and
ffs2 on QNX). Moreover, the mkefs on QNX doesnt accept the ffs2 or ffs3
arguments with the -t option, but returns with error:
“Unknown filesystem ‘ffs2’” or “Unknown filesystem ffs3”. Seems like the
mkefs on QNX is some older version than the one on Windows.
This is a bit unconvinient if I want to use the same mkflashimage script on
both of the systems. Have I installed the system wrongly? How can I verify
the mkefs versions?
Thanks,
Martin
