[lwip-users] initialisation of lwIP

[franz keuner]

Hello,
 
I tried the proposed values but the result is always  the same. (Assertion
"mem_malloc: !lfree->used" failed; "mem_malloc: allocated memory not above
ram_end.""mem_malloc: allocated memory properly aligned.")

>> #define MEM_SIZE                2000U

>Maybe this is too small, try 3000U.

>> #define PBUF_POOL_SIZE          24U

>> #define PBUF_POOL_BUFSIZE       500U

>This is too small, try at least 590U. This is chosen to fit
>the minimum packet size an IP host must handle! (plus MAC frame)

I also changed my makefile and tried different build orders. The makefile
order I`m using at the moment is listed below.

The environment is Tasking Embedded Development Environment (EDE) v.2.7r5,
Selected Toolchain
Tasking Tools for C166/ST10 v7.5r5.

I couldn`t find any information concerning lwIP, the Tasking linker and my
problem.

I list a few  settiings I made in the Tasking EDE. Maybe there`s something
not appropriate.

EDE -> CPU Configuration -> Advanced -> Syscon: 0004h
EDE -> C Compiler options -> Code Generation (Memory Modell) -> Small
EDE -> Linker Locator Options -> Format Options -> 16hex record
EDE -> Linker Locator Options -> Memory -> ROM areas-> 0h-0DFFFh,
010000h-03FFFFh
EDE -> Linker Locator Options -> Memory -> RAM areas-> 200000h-27FFFFh

I tried different settiings but the board either responds always with the
described messages or the linking process isn't executable. 

The board phyCORE-167 HS/E:
Infineon C167CS
Cirrus Logic CS8900A Ethernet controller
512 KB SRAM 
256 KB Flash
16-Bit multiplexed mode

I took the values of the BUSCON/ADDRSEL registers from the manual.

So i always get the same messages whatever I tried so far...


Regrards and thanks,

Franz
