Hi team,
tda4vh sdk8.6
Customer is debugging a 100m chip. Requirements: Obtain IP or static IP, ping. Such as DHCP, acquire IP, setting up a DHCP server on a PC. Currently soc ->mac->phy->pc can receive packets, while the PC does not receive packets to DHCP offer machine, but there is a waveform on Rx. Rx IRQ for Linux OS Mac does not trigger. Static IP ping, PC->ti SoC receive interrupt count does not change.
The DMA does not send an Rx interrupt to SoC. How to troubleshoot why DMA is not sending interrupts? What is the mechanism for sending interrupts? According to the waveform, Rx is sent to SoC with data. And PHY sends data to SoC:
SOC=phy, and the pin soc used is as follows:
Could you help check this case? Thanks.
Best Regards,
Cherry
