Type of issue

• Instructions in the learning path do not work.
• Spelling error in the learning path.
• Instructions in the learning path are hard to follow.
• Instructions to contribute a new learning path are not clear.
• Other

Describe the issue
Instructions in <Developer Hub/Learning Paths/Learning-Paths/Embedded and Microcontrollers/Introduction to TinyML on Arm using PyTorch and ExecuTorch/Set up the Corstone-320 FVP> do not work at:

Test that the setup was successful by running the run.sh script for Ethos-U85, which is the target device for Corstone-320:
./examples/arm/run.sh --target=ethos-u85-256

The error output is:
