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?

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.

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.
