NIOS II-Using FLASH programmer to download the correct procedure, but do not run ok !

Hardware system: EP2C8 + EPCS4 + SDRAM + LED + LCD

Hardware Background: Using Verilog code to write, compile, AS manner POF file to EPCS4, off electricity, the electricity, the normal functioning properly --- LED flashes Shuo, LCD graphic display properly. (Make sure the circuit is no problem about EPCS4)

Software systems: NIOS II

The problem: Run as Mode, LED normally flashes, LCD can also display graphics properly. Downloaded to EPCS4, closing the electric, power, LED will normally flash, But LCD no display!

ing FLASH programmer download, print out a letter of interest rates is as follows:

# !/bin/sh # # This file was automatically generated by the Nios II IDE Flash Programmer. # # It will be overwritten when the flash programmer options change. #
