[lwip-users] Nios II TSE MAC

[Davide Conte]

Dear all,
I'm using the Bill Auerbach's lwIP implementation on Nios II Development 
kit Stratix II edition (rohs).
I am experiencing some problems with memory allocation: it seems that 
the call alt_remap_uncached causes a sort of misalignment of dma data, 
so structure pointers became inconsistent. The annoying thing is that in 
most cases the whole system appears to be tolerant to the fault and the 
flow carries on through random memory locations but sometimes a simple 
call to a free makes the pointer structure to collapse and the system to 
go in error.

best regards,
Dave
