EMAC Interrupts on ZOOM AM3517 EVM

Other Parts Discussed in Thread: AM3517

I’m currently in charge of porting our uC/OS-II and uC/TCP-IP to the TI AM3517. My development board is a ZOOM AM3517 EVM. I have run into an issue while developing the Ethernet driver, the issue that I have is that IRQs 67 through 70 (Ethernet IRQs) are not getting triggered. I’ve followed the documentation during development, the registers that control EMAC interrupts are being enabled but still nothing seem to be triggering the said IRQs. I was wondering if you could assist me with the issue.

I'm using IAR EWARM 6.50.2 and running the board in DDR configuration.

Thank you,

One thing to try perhaps is to see if the phy link is good. What does the (from the TRM) 22.4.4 PHY Link Status Register (LINK) 0x5C03 000C have in it?

They are set to 1.

I think the root of the issue has to do with the L3 interconnect. I think that my ETHER_TX and ETHER_RX signals are not going through. Maybe something is blocking them like a firewall.

I'm getting a 1 for HOSTPEND in MACINVECTOR, the error that reports is TXERRCODE 5h.
