AM3359: ICSS-EMAC Tx ISR not called

Hiren Bhuva

Part Number: AM3359

Hello Community,

I am trying to port the switch example of the using PRUSS and ICSS-EMAC driver.

I am able to send and receive the packets using the PRU ports.

Switch functionality is also achieved. When packet is sent from the host side I am expecting the TX ISR to be called when the packet is sent on the wire.

I am able see the packet in the wireshark. But, I am not getting the TX completion interrupt at the host side.

At host side I am getting RX and Link interrupts as expected.

Below is my pru event to host interrupt map macro.

#define PRUSS_INTC_INITDATA {   \
        { PRU_ARM_EVENT0, PRU_ARM_EVENT1, PRU_ARM_EVENT2, PRU_ARM_EVENT3, PRU_ARM_EVENT4, PRU_ARM_EVENT5, PORT1_RX_EOF_EVENT,\
            PORT2_RX_EOF_EVENT,MII_LINK0_EVENT,MII_LINK1_EVENT,0xFF}, \
        { {PORT1_RX_EOF_EVENT,CHANNEL0, SYS_EVT_POLARITY_HIGH ,SYS_EVT_TYPE_PULSE},\
            {PORT2_RX_EOF_EVENT,CHANNEL1, SYS_EVT_POLARITY_HIGH ,SYS_EVT_TYPE_PULSE}, \
            {PRU_ARM_EVENT0,CHANNEL2, SYS_EVT_POLARITY_HIGH ,SYS_EVT_TYPE_PULSE},\
            {PRU_ARM_EVENT1, CHANNEL3, SYS_EVT_POLARITY_HIGH ,SYS_EVT_TYPE_PULSE}, \
            {PRU_ARM_EVENT2,CHANNEL4, SYS_EVT_POLARITY_HIGH ,SYS_EVT_TYPE_PULSE},   \
            {PRU_ARM_EVENT3, CHANNEL5, SYS_EVT_POLARITY_HIGH ,SYS_EVT_TYPE_PULSE}, \
