How to handle "30525: Illegal instruction (hart 0) at PC 0x0000208c: 0x304022f3"?

[deeplearner92]

Upon executing the test code example given in the Simulation - Vicuna documentation (https://vicuna.readthedocs.io/en/latest/01_user/simulation.html), although I am able to get the outputs, I am getting an additional line "30525: Illegal instruction (hart 0) at PC 0x0000208c: 0x304022f3". Any idea to resolve this? I have set up the environment along with the paths correctly.

From what I've seen, to finish the simulation, they do an invalid operation, if we replace “asm volatile(”jr x0“);” with a “while(1);” the program doesn't give an error but it doesn't finish.
