Forum Post: RE: CCS/TMS570LC4357: ETHERNET is working only in the debugger mode for this launchpad

Rahul, Do you use TI TMS570LC4357 Launch pad (a red board) or your own hardware with this chip? The launch pad doesn't need external power supply, we typically use the micro B USB cable to connect it to a host machine, for both power supply and UART. I tried the LWIP demo on this card a moment ago, I have no issue to get the phyID and run the test. I attached my binary here, may be you can load via JTAG to see if this work for you? You need a USB cable and an Ethernet cable connect to a network with a DHCP server My log: HERCULES MICROCONTROLLERS Texas Instruments Little Endian device Initializing ethernet (DHCP) DEBUG - Getting PHY ID....SUCCESS DEBUG - Getting PHY Alive Status...SUCCESS DEBUG - Getting PHY Link Status...SUCCESS DEBUG - Setting up Link...SUCCESS ..DONE Starting Web Server..DONE HERCULES MICROCONTROLLERS Texas Instruments Little Endian device Device IP Address: 158.218.116.241 Webserver accessible @ http:\\158.218.116.241 Then I can ping it: c:\>ping 158.218.116.241 Pinging 158.218.116.241 with 32 bytes of data: Reply from 158.218.116.241: bytes=32 time=4ms TTL=253 Reply from 158.218.116.241: bytes=32 time=2ms TTL=253 Reply from 158.218.116.241: bytes=32 time=2ms TTL=253 Reply from 158.218.116.241: bytes=32 time=2ms TTL=253 Ping statistics for 158.218.116.241: Packets: Sent = 4, Received = 4, Lost = 0 (0% loss), Approximate round trip times in milli-seconds: Minimum = 2ms, Maximum = 4ms, Average = 2ms c:\> Also, I can use web browser to open this IP address (this demo is a static webserver).
