PROCESSOR-SDK-AM335X: CPSW port overflow

fly100

I found a issue . Firstly the CPSW can receive normally, but when I transmit a great lot of data to the port in a very short time, the CPSW receive will overflow, the register in the CPSW_CPDMA module ,DMASTATUS, which value is 0x00002000,meens " 0010 - Ownership bit not set in input buffer.",the port can not receive data anymore.

I want to know how to avoid this condition happen.

thank you very much.

Which is true? This forum supports only the Processor SDK (Linux, Linux-RT and RTOS), as provided by TI. We already commented this here: e2e.ti.com/.../2127527
