Hello to all.
Wrote an application to exchange packets between FPGA and PC using TCP / IP NicheStack. FPGA is using Cyclone III and the whole program runs from external SRAM. The project starts successfully when loaded via JTAG. The problem appears when the application is copied from flash memory to external memory and starts working from it.
IP address initialization error
MAC post-initialization: MD _CONFIG=0x04000203

Refers to the fact that I could not allocate memory from the ip.c file
#ifdef IP_ROUTING
/* alloc space for the route table */
rt_mib = (struct RtMib*)RT_ALLOC(ipRoutes * sizeof(struct RtMib));
if (!rt_mib)
{
# ifdef NPDEBUG
dprintf("IP_INIT ERROR: can't alloc route table\n");
# endif /* NPDEBUG */
return(ENP_NOMEM);
}
How to increase the amount of memory and from what memory is allocated for initialization?
