Introduction

After downloading the flash programmer by using the niosii flash programmer, the problem that the program cannot be started from the new source is concentrated in the following versions:

1. 9.0sp2
2. 9.1, 9.1sp2
3. 11.0

Basically, there are bugs in these series FLASH leader versions. Among them, 11.0 cannot be erased when the JIC is downloaded.

 

Solution: SOF + elf> flash> hex> JIC

According to Edison, it is learned that there are predecessors on alteraforum to provide a solution. It seems simple, but the curative effect is better.

1. In the qii project folder, create a folder. Take SOF + elf_jic as an example;
2. Copy SOF and elf compiled by qii and NII to this folder;
3. Create a new SH file in the following format, named make_hex.sh here; (SH file, bash batch file; similar to Doc BAT file)

   Sof = "de0_nano.sof" elf = "de0_nano.elf" Echo "sof> flash... "; sof2flash -- EPC -- input = $ sof -- output = HW. flash -- quietecho "elf> flash... "; elf2flash -- EPC -- after = HW. flash -- input = $ elf -- output = Sw. flashecho "cat flash... "; cp hw. flash hw_sw.flash; cat sw. flash> hw_sw.flashecho "Flash> hex... "; nios2-elf-objcopy -- input-target SREC -- output-target ihex hw_sw.flash hw_sw.hexecho" del flash... "; RM-f *. flash

4. Modify 1st ~ 2. Save the name of the row. Start>Program> Altera> niosii eds XX. x> niosii XX. x command shell. Here we use the niosii 10.1 command shell for demonstration (figure 1 ).
   
   Figure 1
5. Open qii> File> convert programming files (Figure 2), remove sof data, and click Generate to generate the JIC.

6. Download JIC directly. OK.
