S32DS MPC5748F enet receive

[ruirui]

When I tried to receive Ethernet packets and convert them to CAN, I ran into problems. I used VECTOR's CANoe to send Ethernet messages and found the corresponding message array in S32DS. However, when I set up the interrupt, I found that the status0 part of rxBD was not updated. Therefore, I cannot complete the sending of CAN messages. The screenshot of my project and the problems I encountered is as follows.<bottom>

Hi,

one possible reason could be data cache. If enabled try to disable it at all, or at least put descriptors and buffer into non-cacheable area. Moreover descriptor have to be properly aligned.
