`make renode` and `make renode-headless` errors in the The Step-by-Step Guide to Building an ML Accelerator #773

Closed FelipeWcosta closed 1 year ago

FelipeWcosta commented 1 year ago

I am trying execute the The Step-by-Step Guide to Building an ML Accelerator as follows:

make enter
cp -r proj/proj_template proj/my_first_cfu
cd proj/my_first_cfu

I noticed differences between the Makefile file of proj/example_cfu and the Makefile file of proj/my_first_cfu but when I try to run the Renode with make renode or make renode-headless it's does not working and show me the following error:

I can run Renode in proj/example_cfu without any errors but with above error when I do it in proj/my_first_cfu.

Observation: I made the changes between the Makefile files and it still doesn't work.

Thankful for the help!

Recently I try to copy proj/example cfu folder to another folder with cp -r proj/example_cfu proj/test_cfu and is appearing the same error.

Hi @FelipeWcosta , it seems to be a tool installation problem. What is your operating system?

From the top directory of CFU-Playground, what do you see under env/conda/envs/cfu-common/bin?

Hmm, do you have a riscv64* toolchain installed somewhere else in your path already? There may be an issue with that toolchain conflicting with the riscv32 toolchain provided by conda (make env / make enter).

Hi @tcal-x, thank you for the reply. Yes, I have riscv64 toolchain in my home dictory, following the directory mentioned I can see the riscv32 toolchain. Can I fix it just with make env and make enter?

tcal-x commented 1 year ago

@FelipeWcosta can you try hiding your riscv64 toolchain by making the directory unreadable (doing something like chmod 000 <directory>)? Then make clean and make renode again...

Good news, it's worked. Grateful for your help @tcal-x
