Nios 2 peripheral register view

[asuperman15]

Hi All!

I'm using Nios II eclipse and I'd like to know if it is possible to have a "peripheral register view" similar to other ICs.

Eclipse Version: Kepler Service Release 2

Hi

There is no register "peripheral view" in NiosII that you are looking for.

What are the settings that you are looking to set?

Hi Jingyang, Teh

Thanks for answering my question. 

I was looking for the registers of some components like PIOs, Timers, etc. to see on live its configuration and in case of the PIOs see the state of the Output when I am debugging my application.

Best Regards,

Alberto

Hi

There is no PIO for the nios2 soft processor.

You could add in the PIO soft IP to interact with certain LED like in the example below:

Hi Jingyang, Teh

Thanks for the example.

I already have added my I/O outputs to PIO soft IP, I just wanted to see such registers information on live on Nios II eclipse.  

Basically, what you are saying is that there is no way to see any defined "component" registers information on live in Nios II eclipse for debugging purposes. 

Is there any way to see this registers information in a structural way?

Hi Alberto

I think you are referring to the register list of the soft ip connected to the Nios2 instead of the Nios2 registers list correct?

If so , to access the registers list of the connected SoftIP like the PIO soft IP connected in your case.

You could assess the register list from the base address of the PIO (PIO_0_BASE ) from the address stated in the "system.h" file generated in the BSP folder.

All the connected SoftIp will address will be listed in the system.h file.

Hi Jingyang, Teh

I like to know if there is a way to see the SoftIP like the PIO as shown in the picture attached.  Where I can see the registers and its content corresponding to the PIO, etc.

Hi

You could find the register map for the PIO Soft IP.

https://www.intel.com/content/www/us/en/docs/programmable/683130/22-1/register-map-33025.html

Once you generate the BSP there are macros that are generate to interface with the soft IP.

For PIO there is this file "altera_avalon_pio_regs.h"

Hi

Any update on this case?

Did you managed to interface with the connected IP from Nios?
