Hi guys,
I am porting lwip1.2.0(not using CVS for updates) to MPC852t with a commercial
RTOS from MQX
I am a beginner in lwip.
Got 2 qs on a problem I am having.
1. MPC852T has a dual port ram with buffer descriptors, which have pointers to
the buffer/frame to be sent
and the Ethernet controller automatically fetch the pointed data for
transmission as soon as I set a flag up.
The problem lies on the fact that the first-in-chain pbuf payload pointer
points to the actual data and skipped the headers,
or at least that is the way I understood it from the manual. I have setup
an array of the same amount of buffer descriptors for
each packet. How do I force the payload pointer of the first-in-chain pbuf
to point to the start of the ethernet header
so that I can assign this to the first buffer descriptor data pointer ?
2. Can someone show me how do I initialise the lwip stack to be used with the
sockets API (maybe the flow)? And is the usage of the
sockets api allows the lwip to be multithreading able ?
Im sorry for the beginner's question and would appreciate it if anyone could
help me out or at least advice me on how to tackle
the 2 things i have in mind.
Thanks a lot
M. Ikhwan Ismail
