DE2_WEB (EXT_FLASH_NAME undeclared)

i'm not sure what the ext_flash.h is supposed to be, but the rest is all due to a mismatch between what your software is expecting to see for your cfi flash's name. your hardware defines a cfi flash named "cfi_flash_0". your software is expecting it to be named "ext_flash".

you should change the software to match your hardware your design has.

Hi slacker,

Thanks for ur reply.

I tried changing the name of Flash, but still the problem persists. http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/sad.gif

"./network_utilities.c - ext_flash.h location" problem was there cuz I included the statement -># include "ext_flash.h" just to check if that solves the problem.

Now, when i look into the module of the hardware design "system_0", I do not see any signals defined for Flash(cfi_flash_0/ext_flash), are they supposed to be there?? and becuz they are not there I get flash declaration error when I build the project in NIOS II?? (SOPC builder file wud be system_0.ptf in this case)

Example: for SRAM signals are:

// the_sram_0

SRAM_ADDR_from_the_sram_0,

SRAM_CE_N_from_the_sram_0,

SRAM_DQ_to_and_from_the_sram_0,

SRAM_LB_N_from_the_sram_0,

SRAM_OE_N_from_the_sram_0,

SRAM_UB_N_from_the_sram_0,

SRAM_WE_N_from_the_sram_0,

=============================================

my hardware part compiles fine in quartus.

Any suggestions??

Thanks,

Mona.
