RM48L952: lwIP does not respond to ping

Cosmin Briceag

Part Number: RM48L952

Hello,

I integrated the lwIP stack 1.4.1 with RM48L952 device and although the hdk is initialized with a static IP it does not respond to ping from another machine (it is connected to a router but it does not show up in router clients list).

Thank you,

Best Regards,

I do not have an FTDI converter to log messages on my PC but please find below answers to your questions.
