Hi,

I have qestions about flow control of CPSW.

Q1: There are CPPI port flow control and Ethernet port flow control. What is the specific difference?
In particular, I don't know what CPPI port flow control does.

Q2: What is P1_FLOW_EN and P2_FLOW_EN in the CPSW_SS_FLOW_CTRL register used for?
What is the difference from RX_FLOW_EN of CPSW_SL_MACCTRL register?

Hi DK,

Thank you for your reply.

I don't think to identify software problems.
I am investigating the functions of CPSW and how to use each register in order to develop software.

So, I want to know the above-mentioned functions (difference between CPPI port flow control and Ethernet port flow control) and how to use CPSW_SS_FLOW_CTRL and its effects to develop software.

Best Regards,
H.U
