IMX8DQ ENET consumption of shared resources

[Kevin_N]

Hello,

I am currently working on the ENET module. I would like to know if it consumes any shared resources during the MAC receive process other than the "Write FIFO data and frame state" step ?

Best regards

Hi,

Thank you for your interest in NXP Semiconductor products,

It does not. The MAC receive process is:

• Check frame framing

• Remove frame preamble and frame SFD field

• Discard frame based on frame destination address field

• Terminate pause frames

• Check frame length

• Remove payload padding if it exists

• Calculate and verify CRC-32

• Write received frames in the core receive FIFO

All of it is performed in ENET module itself.
