AM3359: PRU interrupt issue

Pankaj Suryawanshi

Part Number: AM3359

Hi Community,

I am referring "ICSS_EMAC_Basic_Example", In which I am not getting Interrupts (Link Interrupt)

Below Print Msg I am getting only "ICSS_EMAC_testTaskPruss1: LINK IS DOWN,skipping PRU1 ETH0".

I have check PHY LInk status using while ((MDIOPhyLinkStatus(SOC_PRU_ICSS_MII_MDIO_REG, PHY_ADDR1) != TRUE)) It is UP, It means I am not getting Link Interrupt ?

Please let me know if i missed anything.

Regards,

Pankaj

Pankaj,

ICSS_EMAC_testLinkIsrPru1Eth0 increases when the link interrupt call back function is activated. The message '"ICSS_EMAC_testTaskPruss1: LINK IS DOWN,skipping PRU1 ETH0".'indicates the interrupt is not triggered as you suspected. If you are certain the link is up, you may need check if the interrupt is mapped correctly.

The document may help - https://processors.wiki.ti.com/index.php/ICSS_EMAC_LLD_developers_guide#Link_Interrupt
