21 years agoThanks everyone.
I have find the answer. I only use EPCS4 to store the elf+sof, so when i made the target board, i didn't add the tri-state-bridge, and now i add a tri-state-bridge, a virtual flash-chip (maybe lan91c111 also can work, i haven't try it), dont make pin assignments for this virtual flash-chip, then rebuild the target board project, and my actual project, and in IDE rebuild the niosII project, then the flash-programmer is ok.
