Have v1.8.3 working now. Don’t understand what happened. The only things I did different was:
- Got into boot mode using menu in v1.8.2
- Downloaded v1.8.3 again - on same PC. Without renaming the file - in the previous attempt I moved the file to different folder and removed (1) in the filename because of another copy already there - installed the uf2.
Don’t know why the first Picoware upgrade to v1.8.3 failed.
Now it is working! Thanks again! Eric
