Part Number: 66AK2E05
Tool/software: Code Composer Studio
Nowadays，I‘m developing the 66AK2E05 to Implement a function that is useing the DSP to receive packets from enthenet port,when I program the PA moudle,I have to program the paRouteInfo_t Struct to configure the routing information that is used to determine the next destination for the packet,I want to configure the destination to host,so I should configure the flowId, queue, mRoutehandle, swInfo0, cmd parameters in this Struct,but I don't know how to configure these parameters,I read the "KeyStone Architecture II Packet Accelerator 2 (PA2) for K2E and K2L Devices User's Guide" and "paRouteInfo_t Struct Reference (pdk_keystone2_3_01_01_04/packages/ti/drv/pa/docs/doxygen/html/structpa_route_info__t.html)",but still don't konw,could you please tell me how to configure it or which regerence I should read,thank you!
that's the Struct:
typedef struct {
int dest; /**< Packet destination as defined at @ref pktDest */
uint8_t flowId; /**< For host, SA or SRIO destinations, specifies CPPI flow which defines free queues are used for receiving packets */
uint16_t queue; /**< For host, SA or SRIO destinations, specifies the destination queue */
int mRouteIndex; /**< For host, Multi-queue routing index (0 to (@ref pa_MAX_MULTI_ROUTE_SETS - 1))
or @ref pa_NO_MULTI_ROUTE if multi routing not used */
uint32_t swInfo0; /**< Placed in SwInfo0 for packets to host or SA; Placed in the PS Info for packets to SRIO */
uint32_t swInfo1; /**< Placed in SwInfo1 for packets to the SA; Placed in the PS Info for packets to SRIO */
int customType; /**< For CONTINUE_PARSE_LUT1/LUT2 only, specifies the custom type as defined at @ref customType */
uint8_t customIndex; /**< For CONTINUE_PARSE_LUT1/LUT2 only, specifies the custom classification entry index */
uint8_t pktType_emacCtrl; /**< For destination SRIO, specify the 5-bit packet type toward SRIO
For destination HOST, EMAC, specify the EMAC control @ref emcOutputCtrlBits to the network */
paCmdInfo_t *pCmd; /**< Pointer to the Command info to be executed prior to the packet forwarding.
NULL: no commads
@note only the following commands are supported within paRouteInfo_t
- pa_CMD_PATCH_DATA (up to two bytes only) (LUT2 only)
- pa_CMD_CMDSET
- pa_CMD_USR_STATS
- pa_CMD_CMDSET_AND_USR_STATS
*/
} paRouteInfo_t;
and that is paRouteInfo_t Struct Reference:
