Tool/software:
Dear Support Team,
The SDK we use is processor_sdk_09_02_01_09, our company has customized the core board and base board based on AM6254, the hardware connection is as follows, one CPSW port ETH0 is connected to PC 1 (e.g. laptop), and the other CPSW port ETH1 is connected to PC 2 (e.g. laptop). Now we want to use CPSW's SWITCH mode, but we have a problem where the board can't ping PC1 and PC2. I collected some log information (am62x log.txt) and CPSW related device tree configuration (cpsw dts.txt). I've been researching for over a week and can't find what the problem is, can you help me see what's wrong? Thank you!
