questions about flash in nios

thanks!

i use flash programmer to download the hardware image and software image, so there are no .jic and .pof file.

and i try to find the .map file, i still can not find it.

someone told me how to genrate the jic file, i try to do that, still failed:

thanks!

i try to generate the .jic file

when i use "sof2flash --epcs --input=ex2.sof --output=hw.flash --verbose" the command shell tell me "please supply an offset where you would like your sof located <--offset>"

so i use "sof2flash --epcs --input=ex2.sof --output=hw.flash --verbose --offset=0x0 "(i do not know whether offset=0 is right)

then the hw.flash file is generated

then i use "elf2flash --ecps --base=0x0 --end=0x7ffff" --after=hw.flash --input=test2.elf --output=sw.flash"(0x7ffff is the size of M25P40 )

then the sw.flash file is generated, but its size is 1Kb and content is

"S00600002D454C3B

S70500000000FA"

i do not think it is right, so i think the base and then end address may not refer to M25P40, so i change them to base and end of EPCS/EPCQx1 Serial Flash Controller in Qsys, that is 0x01001000 0x010017ff

then i use "elf2flash --ecps --base=0x01001000 --end=0x010017ff" --after=hw.flash --input=test2.elf --output=sw.flash"

then the command shell tell me

"elf2flash: Boot copier file name required

elf2flash: Error generating Flash file, exiting"

i do not know where to find the Boot copier file....

can you give me more advise?

thanks!
