hey @qelk123, sorry I missed this. it looks like maybe the script is requiring you to configure the attached board serial number. This is being passed to `hla_serial` given to openocd.
I think the root cause error is this line: `expected exactly one argument to hl_serial <serial-number>` It's been a while since I've run this demo but you might try examining `env-config.json` in the microtvm-blogpost-eval repo and see if you've specified hla_serial. or, you could edit `microtvm-dev-config/openocd.cfg.template` and remove the `hla_serial` line. let me know if this solves your problem.
