Hola a todos, resulta que estoy utilizando un PIC18F67J50 con un ENC28J60 como tarjeta de red para implementar un sistema ethernet y tengo un problema que no sé como solventar a ver si alguien que tenga mas experiencia en esto me echa una mano.
Con el pic estoy utilizando una memoria externa 25LC1024 que es la que viene por defecto en las librerías.
Si solo implemento el servidor telnet todo va bien, tengo comunicación y todo lo demás, pero si le implemento el servidor web ahí ya no me funciona el asunto.
Siguiendo el rastro del programa donde veo que se queda en espera es en este trozo de código que pertenece a la librería TCP.c
switch(vMedium)
{
#if TCP_ETH_RAM_SIZE > 0
case TCP_ETH_RAM:
ptrBaseAddress = wCurrentETHAddress;
wCurrentETHAddress += sizeof(TCB) + wTXSize+1 + wRXSize+1;
// Do a sanity check to ensure that we aren't going to use memory that hasn't been allocated to us.
// If your code locks up right here, it means you've incorrectly allocated your TCP socket buffers in TCPIPConfig.h. See the TCP memory allocation section. More RAM needs to be allocated to the base memory mediums, or the individual sockets TX and RX FIFOS and socket quantiy needs to be shrunken.
#if defined(WF_CS_TRIS)
while(wCurrentETHAddress > TCP_ETH_RAM_BASE_ADDRESS + WFGetTCBSize()/*TCP_ETH_RAM_SIZE*/);
#else
while(wCurrentETHAddress > TCP_ETH_RAM_BASE_ADDRESS + TCP_ETH_RAM_SIZE);
#endif
break;
#endif
#if TCP_PIC_RAM_SIZE > 0
case TCP_PIC_RAM:
ptrBaseAddress = ptrCurrentPICAddress;
ptrCurrentPICAddress += sizeof(TCB) + wTXSize+1 + wRXSize+1;
// Do a sanity check to ensure that we aren't going to use memory that hasn't been allocated to us.
// If your code locks up right here, it means you've incorrectly allocated your TCP socket buffers in TCPIPConfig.h. See the TCP memory allocation section. More RAM needs to be allocated to the base memory mediums, or the individual sockets TX and RX FIFOS and socket quantiy needs to be shrunken.
while(ptrCurrentPICAddress > TCP_PIC_RAM_BASE_ADDRESS + TCP_PIC_RAM_SIZE);
break;
#endif
#if TCP_SPI_RAM_SIZE > 1
case TCP_SPI_RAM:
ptrBaseAddress = wCurrentSPIAddress;
wCurrentSPIAddress += sizeof(TCB) + wTXSize+1 + wRXSize+1;
// Do a sanity check to ensure that we aren't going to use memory that hasn't been allocated to us.

while(wCurrentSPIAddress > TCP_SPI_RAM_BASE_ADDRESS + TCP_SPI_RAM_SIZE);
break;
#endif
default:
while(1); // Undefined allocation medium. Go fix your TCPIPConfig.h TCP memory allocations.
}
se queda esperando en el while(1); //Undefined allocation medium. Go fix your TCPIPConfig.h TCP memory allocations., según dice ahí, si la traducción no me falla, Indefinida la localización de medium, ve a TCPIPConfig.h localización de la memoria TCP.
yo voy al archivo de configuración y lo que veo es esto

creo que van por aquí los tiros pero he probado muchas combinaciones pero no doy con la tecla.
Según creo, una vez que implementes el servidor web, con la herramienta MPSF2 que viene en la librería cargarías la web en la memoria SPI vía ethernet ¿Cierto o tengo que cargar el fichero con un programador de eeprom y ese es el problema?.
He de decir que estoy utilizando una PCB desarrollada por mi, nada de desarrollos comerciales
