Error in test overlay in Packaging-An-Overlay/Installing the Tutorial Overlay

[braziperjikolaei]

Hi dear all,

I try to implement picorv32 on PYNQ-Z1 using vivado 2019.2 I followed your instructions until Packaging an Overlay. Testing the Tutorial Overlay failed due to the same error mentioned in issue #20 . However I can install the Tutorial Overlay via pip3.6 install --upgrade /home/xilinx/RISC-V-On-PYNQ/ and first two commands produce no error:

from riscvonpynq.picorv32.tut.tutorial import TutorialOverlay
overlay = TutorialOverlay("tutorial.bit")

But the next command

%%riscvc test overlay.tutorialProcessor

int main(int argc, char ** argv){
    unsigned int * arr = (unsigned int *)argv[1];
    return arr[2];
}

give this error:

I do appreciate if you could help me to solve this issue.

Kind regards Behnam

Hello Behnam!

May I ask if you solved the issue? I am facing the same problem and get the following error:

I would be grateful for your help Best Regards

Was this issue resolved? I'm trying to run the RISC-V Example Cores on my PYNQ Z2 with v2.5 img but getting the same error.

If I remember correctly, I downgraded the PYNQ image on my board, to the version of the tutorial and it worked for me.

I did the same, it worked only when I installed the older version from the tutorial

[thetushargoyal]

@Alikhanum Which version did you install?
