8 Working with ltib
The “ltib” system is a build environment and package manager for the Freescale SDK. A few tips
on ltib usage follow.
• ltib --help : list ltib options
• ltib -m listpkgs : get a list of available packages. The USDPAA package is called “usdpaa”
• ltib --mode prep --pkg usdpaa : unpack usdpaa source code into directory rpm/BUILD.
The proof of concept application is rpm/BUILD/usdpaa-0.3.0/apps/reflector.
• ltib : with no options, ltib will just build. For example, you could edit reflector/reflector.c
and then just run ltib again to build it. It builds a new Linux file system for use on the
p4080.
9 Known Limitations of this Release
You may run only a single USDPAA application instance at a time. The application
may be (usually is) multithreaded.
When heavy traffic is received on 10G ports for which the policy file has a
classification rule that does match the traffic type (for ex: policy file has TCP tuple
classification but traffic received is UDP), bman_acquire failed logs are seen on P4080
console. However, this does not impact the traffic. Occasionally the RX rings on host
are stalled
The Ethtool support for the x86 host driver is limited to driver info, ring parameters,
statistics, get/set Tx checksum. Link state reporting is not included as a P4080 USDPAA
10G Phy driver isn’t available.
