The P2020DS-PA board and P2020RDB-PA board ship with Linux v2.6 and support for IEEE 1588. Both boards are supported by CodeWarrior v8.8,

Wind River, Green Hills and MontaVista development environments. The P20220DS-PA is a highly integrated development system that can be

utilized to bring your design to market. The P2020RDB-PA is a low-cost reference design board based on the mini-ITX form factor.
