renode error related to conv and software elf

[rajsaktish]

Hello,

@tcal-x
@danc86

I am facing the following error during make renode.
FYI, riscv32 toolchain has been installed for Ubuntu and added to $PATH. Confirmed this by typing riscv32 (tab, tab, tab)

src/tensorflow/lite/micro/kernels/conv.cc: In function 'TfLiteStatus tflite::{anonymous}::Eval(TfLiteContext*, TfLiteNode*)':

Any help is appreciated.

Thanks

I think the proj/mnv2 subdirectory is not covered by CI so it's possible that it was broken by a recent update to TfLM.

Try compiling proj/proj_template or making your own project based on that one as a template. It should be up to date.

While @danc86 's answer perfectly fits the symptoms that @rajsaktish reported, and in fact we've seen and fixed these ourselves a few times, I have some new data:

• mnv2_first is run in CI (by test-projects.yml) and is passing
• I just ran the following myself in a new updated sandbox on branch main:

% cd proj/mnv2_first
% make renode

and it worked correctly.

So I think if you update to current latest main, then rerun ./scripts/setup, and then try again, it might work.

Please try and let us know if that fixes it.
