1.2.5.9.2 MIIM Driver Configurations

MIIM Driver Specific User Configurations

• Maximum Number of Clients:

  • MIIM number of clients

  • This definition select the MIIM Maximum Number of Clients per instance.

  • Notes:

    • By default the 1st MIIM client is the DRV_ETHPHY.

    • An extra client is allowed (to perform operations from the console).

  • Default value: 2

  • Symbol DRV_MIIM_INSTANCE_CLIENTS

• Stack Size (in bytes):

  • The size of the stack for the task running the MIIM driver in an RTOS environment

  • Default value: 4096

  • Symbol DRV_MIIM_RTOS_STACK_SIZE

• Task Priority:

  • The priority of the task running the MIIM driver in an RTOS environment

  • Default value: 1

  • Symbol DRV_MIIM_RTOS_TASK_PRIORITY

• Use Task Delay:

  • Enable the delay to wait/sleep for the task running the MIIM driver in an RTOS environment

  • Default value: true

  • Symbol DRV_MIIM_RTOS_USE_DELAY

• Use Task Delay:

  • The delay value to wait/sleep for the task running the MIIM driver in an RTOS environment

  • Default value: 1

  • Symbol DRV_MIIM_RTOS_DELAY

• ETH Module ID:

  • The Ethernet Module ID of which this MIIM module belongs to

  • Default value: GMAC_BASE_ADDRESS/_ETH_BASE_ADDRESS/EMAC0_BASE_ADDRESS/EMAC1_BASE_ADDRESS

  • Symbol DRV_MIIM_ETH_MODULE_ID

• Number of Driver Instances:

  • This definition selects the maximum number of hardware instances that can be supported by the dynamic driver.

  • Usually set to 1.

  • Default value: 1

  • Symbol DRV_MIIM_INSTANCES_NUMBER

• Maximum Number of Queued Operations:

  • This definition selects the maximum number of simultaneous operations that can be supported by this driver.

  • Note that this represents operations for all clients

  • Default value: 4

  • Symbol DRV_MIIM_INSTANCE_OPERATIONS

• Enable Client Operation Protection Feature:

  • Because of the recirculation of the operation handles and client handles the possibility exists that a misbehaved client inadvertently gets the results of a previous completed operations that now belongs to a different client.

  • When this feature is enabled, extra protection is added for an operation handle to uniquely identify a client that has started the operation and extra check is done that operation belongs to the client that asks for the result.

  • Notes:

    • Set the value to 1 to enable, 0 to disable the feature.

    • Enabling this feature requires a small overhead in code and data size.

  • Default value: false

  • Symbol DRV_MIIM_CLIENT_OP_PROTECTION

• Enable MIIM Commands:

  • Enables/Disables MIIM commands feature.

  • It adds a MIIM command to the TCP/IP command menu allowing to read/write a PHY register.

  • Note:

    • Currently the MIIM commands are integrated in the TCP/IP commands. To have the MIIM commands available the TCP/IP commands need to be enabled.

  • Default value: false

  • Symbol DRV_MIIM_COMMANDS

• MIIM Driver Object:

  • The object to use for the MIIM driver.

  • Default value: DRV_MIIM_OBJECT_BASE_Default

  • Symbol DRV_MIIM_DRIVER_OBJECT

• MIIM Driver Object Index:

  • The index of the MIIM driver object

  • Currently this index is set to 0

  • Default value: 0

  • Symbol DRV_MIIM_DRIVER_INDEX
