So maybe check inode > size (should be 256 bytes I think?). I don't have tune2fs on my embedded system, so I can't check, but that sounds like the probable reason. The nanoseconds that ext4 added are in the upper 128 bytes of a 256 byte inode, for compatibility reasons, so somehow I must have ext4 configured to use 128 byte inodes. Where would this be configured in a Yocto build? I'm still on Pyro. -- Ciao, Paul D.

I think file timestamp resolution on ext4 is one of the things that depend on inode size (ext4 does not enforce reasonable values because of compatibility with earlier versions I guess). So maybe check inode size (should be 256 bytes I think?). Jussi -- ___ yocto mailing list yocto@yoctoproject.org https://lists.yoctoproject.org/listinfo/yocto
[yocto] One second timestamp resolution?
I just noticed that I'm getting one-second resolution on all my timestamps. This is for both ext4 and vfat partitions, and shows up in ls --full-time and the stat command. What could account for this? My uname -a output is "Linux CHROMA1 4.10.17-yocto-preempt-rt #1 SMP PREEMPT Wed Oct 11 12:33:54 PDT 2017 i686 i686 i386 GNU/Linux" if that's any help. Also, my ext4 mount options are "rw,noatime,nodiratime,data=ordered". -- Ciao, Paul D.
