hello , 

who can tell me what's mean of the error?    ***[cfi_flash_0.flash]Error 5  57PM-(??)elf2flash:Boot copier overlaps data in flash[Jan 25,2005 5]   57PM-(??)elf2flash:Error generating Flash file,exiting[Jan 25,2005 5]

If you set your reset address to point to flash and your text segment to a different memory then elf2flash will try to put a small piece of code (the boot copier) into flash at the reset address which copies your code and data from flash to the memories you specified. 

 This error message indicates that you have used the flash where the boot copier would go for something else, so the boot copier can't be inserted. This means that your system probably won't function.  Are you using one of the standard designs? Which memories did you set your code and data segments to?

hello,  

i used my own design, my flash is 2M, the address is from 0x000000 to 0x1fffff,  i set    Reset Address cfi_flash_0 0x00000000 0x00000000  Exception Address cfi_flash_0 0x00000020 0x00000020    Program Memory sram_0 0x00200000  Data Memory sram_0 0x00200000  Host Communication uart_0 0x00310000  Debugging Communication uart_0 0x00310000

I think your problem is caused by your exception address pointing into flash. Try putting the exception address in sram. 

 This will get you better performance as well, as the exception handler should be in fast memory.
