NIOS II reset

[Altera_Forum]

Hi, 

 I am connecting the board reset to the NIOS II reset input in the qsys design. The reset vector address is set to the onchip memory. I use the eclipse tool to download my software application. On board reset I see that the application does not execute again. I will have to download the application again to get it working whereas there is no need to program the .sof file on reset. What is the reset requirement of the NIOS II processor. How can I fix this issue.  Thanks & Regards Bhavya K

Is the same board reset connected to the onchip memory as well?

Hi, 

 Yes the same reset is used for the onchip memory as well.

Can you attach your Qsys system?

[Altera_Forum]

It is quite a big system now, so there are many things in the qsys system. You can have a look

Also you will need to connect the jtag_debug_module_reset to all Nios peripherals including onchip-memory.

[Altera_Forum]

So you mean to say everything controlled by NIOS should have the jtag_debug_module_reset connected to it?

Yes. It is recommended to connect the same reset sources to Nios and its peripheral to ensure that they get reset at the same time.
