Sorry but something was wrong on the merge request:

my modification is to add a methode:

  private String getChip() {
    String targetBoardId = BaseNoGui.getTargetBoard().getId();

    if (targetBoardId.contains("s2")) {
      return "esp32s2";
    }
    else {
      return "esp32";
    }

  } 

and call it each time you need to set "chip", ex:

sysExec(new String[]{esptool.getAbsolutePath(), "--chip", getChip(), "--port", serialPort, "--before", "default_reset", "--after", "hard_reset", "erase_flash"});
