Hello, I am using your company's AM2732 + PHY chip dp83tc812 board, UDP transceiver program when encountered problems, I generated a UDP server program based on the official enet _ cpsw _ udpserver routine, and then replaced the phy driver with the dp83tc812 driver, Connected to the PC's sscom for testing, when sending, it returned an error, sendPckt sendto: error "Routing problem.", The location of the error in the program is the udp _ sendto _ chksum () function in udp.c, which returns ERR _ RTE, I don't know how to solve this problem, Also, how to compile the code corresponding to the library file into CCS, so that you can see the debug information?
