      I just got my M5Stack Fire. I checked the ram and version in a terminal and saw the
      UIFlow version was 1.3.3 with
      MicroPython v1.10-279-gfc77b5bbf-dirty on 2019-06-19; ESP32 module with ESP32

      and the free RAM was about 2031776.

      I upgraded the UIFlow to 1.4.5.1 and got the MP version of
      MicroPython v1.11-312-g944acf81d-dirty on 2020-03-13; ESP32 module with ESP32
      but now the free RAM is about 71360.

      How can I get the current version of UIFlow to recognize the PSRAM, how do I get a version that will use the RAM, or how can I get back to the factory installed version?

        As far as i'm aware it's only possible to use the psram when programming the m5stack with arduino. There is currently no way to utilize the psram with micropython at least not with uiflow

          Is there any way to reinstall the factory installed UIFlow version 1.3.3?
          It gave 2,031,776 bytes of RAM as opposed to the 71,360 bytes
          available with UIFlow 1.4.5.1.

            The latest M5Burner version, 2.1.0, has a UIFlow version for the Fire.
            UIFlow v1.5.3-fire Micropython v1.12-548-gfc090afb5-dirty REPL
            shows 4078864 when you run gc.mem_free as opposed
            to less than 92000 with the older version 1.4.5.1 that I could not find in a Fire version.

                @acuralegendz when you start uiflow desktop or m5 burner make sure to choose allow incoming network connections. The software needs to connect to the server so it can get the latest firmwares
