Nios V/g program doesn't start

[HarutyunUMRSHATYAN]

Hi, we made a design with Nios V/g Processor using Intel Quartus Prime and trying to run a simple elf on it using RiscFree IDE. The program doesn't start since it falls into a trap because of an illegal instruction exception. These are the compile options we got from bsp generated:
-march=rv32ima_zicbom -mabi=ilp32

and this is where exception is thrown in file crt0.S:
/*
* Initialize the data cache if present (i.e. size > 0).
* Skip initialization if optimizing for RTL simulation.
* RTL simulations can ensure the data cache tag RAM is already
* initialized so skipping this speeds up RTL simulation.
*/
#ifndef ALT_SIM_OPTIMIZE
#if ALT_CPU_DCACHE_SIZE > 0
li t0, ALT_CPU_DCACHE_SIZE
0:
/* cbo.inval.ix */
/*!!!NIOSV_ILLEGAL_INSTRUCTION!!!*/
.insn i 0x0F, 0x2, zero, t0, 0x080
addi t0, t0, -ALT_CPU_DCACHE_LINE_SIZE
bnez t0, 0b
#endif /* Initialize Data Cache */
#endif /* ALT_SIM_OPTIMIZE */

Could you please help us figure out this situation?
Thank you in advance!

Hi,

Greetings and welcome to Intel's forum.

May I know the Quartus version you are using to compile your NIOS V design? Also, is the OS you are using to compile the project Windows? As NIOS V works best with Linux and many errors can be eliminated on Linux OS.

Hope to hear from you on your feedback.

Thank you.

Hi,

Thank you for your response.

We are using Quartus Prime Version 23.1.0 on Ubuntu 20.04 LTS.

Hi,

Any updates from your end whether the information provided was useful to solve your issue?

By any chance, would you consider using Linux OS for NIOS V?

Thank you.

Hi,

Just to confirm whether you have launch RISC Free IDE through the NIOS V command shell?

You my have a look on the debugging steps for the NIOS V processor here: https://www.intel.com/content/www/us/en/docs/programmable/730783/23-1/debug-setup-for-processor-system.html

Thank you.

Hi,

Sure we launch RISC Free IDE through the NIOS V command shell.

I create an empty cmake project and import my code there. All this setup works good with NiosV/m but I cannot make it work with NiosV/g.

Hi,

For the Quartus version you are using, is it a Standard or a pro version?

Hope to hear from you on your feedback.

Thanks.
