UPDATE   I found a solution.  I'm using the esp32>ESP32 Dev Module B board driver instead. This gives me the partition scheme option and I've made it “Huge APP ( 3MB No OTA/1MB SPIFFS)”  option.

It would still be good as to why the  esp32>Firebeetle-ESP32 suddenly stop working?  I suppose that the board.txt file was overwritten with the update and the partition scheme option was set back to default?
