No Nios II target connection paths were located. Check connections and that a Nios II

Did you check what the dev tools suggest. I mean:

- did you download the correct .sof

- does the fpga project, which the .sof comes from, contain a valid Nios system?

- did you insert the jtag module in Nios?

- (last, maybe silly, question) is the jtag cable correctly connected?

Erm... I build the system with belowed step:

i) generate a SOPC system with jtag(default setting), nios II with custom instruction, sdram and on-chip memory.

ii) assign pin for my system such as clk and etc

iii)compile and synthesize

iv) go to eclipse browse for my SOPC file and select "hello world" template

v) build the software and run as hardware with my usb plug in(i can see my usb detected from device manager)

error occur during run as hardware and a window is prompt with stated error.

Is my step correct? because i follow the guideline that been found from internet.

You are missing a step: before "run as hardware" you should configure the fpga with the .sof file generated at step iii.

Are you indeed missing it or you simply forgot listing it?

Hi guys,

I have solved this problem by following the below steps.

Go to-- NIOSII--BSP Editor--File--New BSP--save the BSP.

Copy and paste it in your BSP.

Then program the chip using .elf.
