Re: [lwip-users] PBUFS + MEMP + LWIP 1.3.0

Hi,

Is there a port of 1.3.2 for the ATMEL UC3A0512 device?

If no where can I get the 1.3.2 LWIP stack.

I am using PPP, and at the moment I am trying to track a bug that causes my 
system to crash, and when I stop me debugger it points to the 
PPPthreadHandle. The failure seems to occur in the function pppInProc() 
everytime.

The change log, does not show any changes to the PPP code,  so I am just 
worried that I am going to waste alot more time to get the port done and 
face the same problems.

I have seen in a website that when physical layer is not present i.e modem 
in my case that the pppThread must be removed.
And that implementation of the thread remove used a function called 
sys_arch_thread_remove, which does not appear in the LWIP 1.3.0, sys_arch.c 
file.

Is there an example of proper use of the LWIP PPP stack that I can look at 
to get some pointers.

The reason I started looking at the memory, is beacuse normally these kind 
of system crashes is related to memory mismanagement or messed up pointers.

Please bear with me, as I may ask some question which may seem dumb, but I 
am fairly new to LWIP stack, and I am trying to get my head around its 
workings.

The only reason my emails are marked High Priority is because when I send 
emails, I want the server to send them immediately without any delays, and 
it has no relevance to your response time, however I thank you for you promt 
response.
