  • Page 7: Introduction

    The BestComm engine is driven by its private tasks which execute from microcode located in the MPC5200 static RAM memory. These tasks are not to be confused with tasks managed by an RTOS such as KADAK's AMX kernel. Within this document, the term task will be assumed to reference a BestComm task unless otherwise specified.

  • Page 13: Special Considerations

    6. Special Considerations 6.1 BestComm Initialization MPC5200 FEC Ethernet Device Driver depends upon the BestComm API KwikNet and microcode supplied by Freescale Semiconductor, Inc. The BestComm microcode must be loaded into memory and initialized once prior to initialization of any of the subsystems that it supports. Each subsystem, such as the FEC, must then start and assume control of the BestComm tasks upon which the subsystem depends.

  • Page 14: Bestcomm Fec Initialization

    BestComm FEC subsystem cannot be reconfigured to meet the revised configuration requested. A custom timing service is implemented in source file MPC5200 FEC device driver. Precise timing is derived from the internal MPC5200 Time Base Register. Procedure bound delay with microsecond precision. This procedure supercedes the crude delay...

  • Page 15: Bestcomm Source Code Modifications

    Note that the BestComm software compiled in this fashion has been exercised using the FEC subsystem only. KwikNet MPC5200 FEC Device Driver BESTCOMM_API.H KN5200E.INC , the equivalent MetaWare keyword.

  • Page 16: Mpc5200 Interrupt Exceptions

    . Doing so resolves the interrupt nesting 0x0500 issue introduced by the non-maskable critical interrupt exception. Also included in the AMX MPC5200 board support module is the AMX Interrupt Identification Procedure which decodes the interrupt source and vectors ch500vd() through the linear AMX Vector Table to the device specific ISP root.
  • Page 17 Exceptions Warning the three MPC5200 exceptions share a common, overlapping region of the AMX Vector Table. The warning can be safely ignored. The MPC5200 FEC device driver provides support for two interrupt sources: the FEC channel and the BestComm FEC subsystem.

  • Page 18: Configuring The Physical Device

    KwikNet can exceed 2 seconds, every time the MPC5200 FEC network interface is opened for use. In a multitasking system, all lower priority activity will be inhibited until the interface is ready or until the timeout interval expires.

  • Page 19: Mode 2: Periodic Sampling

    Mode 2: Periodic Sampling By default, the MPC5200 FEC device driver is configured to use a third, preferred method of operation. The driver uses a timer to periodically sample the PHY, KwikNet watching for the auto-negotiation to complete. The sampling period, the wait interval and an additional post-negotiation delay are all configurable parameters.

    Appendix C of that manual KwikNet illustrates the layout of a data sheet used to describe each unique device driver. KwikNet MPC5200 FEC Ethernet Device Driver conforms to the naming conventions KwikNet and operating specifications presented in the Device Driver Technical Reference KwikNet Manual.
