lwip and SDRAM memory

Question asked by matilda on Feb 16, 2012

hello,

Im using BF548 with visual dsp 5.0 update 9.

I use the lwip and when I allocate a static buffer in the sdram bank0 I get fatal exception. (till now I didn't use the sdram)

When this buffer is allocated in the internal memory everything is ok.

I see that the memp allocation returns addresses in the sdram bank0 (for example 0xb68 is received when calling tcp_new())

and so my buffer overwrites the memory pool.

My question: I can I know exactly which memory area is used by the lwip and I can I "mark" the application not to use this memory?

Thanks a lot
