I am currently investigating firmware of an embedded system (car navigation) and have identified the OS as QNX.
The firmware has .ifs files which I was able to extract/unpack using QNX dumpifs tool and .img files. The .img files do not appear to be compressed, is there a file format or dump tool for QNX .img files?
/edit: some extra information file -sL file.img reports x86 boot sector Mount attempt in Ubuntu mount -t qnx6 ./file.img -o loop/dev/loop1,blocksize=512 /media/qnx fails with wrong fs type, bad option, bad superblock on /dev/loop1
dmesg reports qnx4: wrong fsid in superblock or qnx6: invalid mount operation
cat /proc/filesystems reports both qnx4 and qnx6
