Hi @dan thanks for your reply. Actually not, also tried with an older VSC version (i.e. 1.25.1) but result is even worst (error: command pymakr.* not found and console doesn't start). Also downgraded Node.js to the LTS (8.12.0) but no luck. Because I'm using VSC for Python and to manage other non-pycom micropython-based boards via terminal it would be comfortable having a single IDE. Is there a particular setup known to work (firmware, VSC, Pymakr, Node.js, versions, platforms and architecture)?
PS: Using Atom 1.31.1 on Win10/64 with Pymakr 1.4.4 I notice no issues, REPL responds correctly.
