[lwip-users] PPP server problem

[LMao]

Hi Sylvain,

 

I try to use PPP server on AT91SAM7x chip and it failed authentication (both sides using PAP). Here’s the debug message from a Linux (PPP client) followed by lwIP PPP debug message. Interesting thing is the PPP authentication failure also causes the whole lwIP stack stop working. I continuously PING my Ethernet interface while I start the PPP client on Linux, after a while, the PING stopped and never come back.

 

Could you take a look at those messages and tell me what could be wrong?

 

Thanks,

 

Charles
