Installing and Updating UIFLow Firmware on the M5Stamp S3 with M5Burner.

The following steps are only for installing or updating the UIFlow firmware on the M5Stamp S3.

If you havent already downloaded M5Burner, visit the M5Stack Download Page. and scroll down to the M5Birner section and then click on the link for the Operating system your host computer is using.

M5Burner can be fussy about where it installed to (may not work). On OSX (Apple) based computers these means that M5Burner need to be placed in the applications folder.

M5Stack compatable firmwares are grouped together by the device they are built to run on and you can sort the fimware selection to specific devices by clicking on the device icon in the right hand side menu.

Clicking on the device icon for the M5StampC3 only show one firmware option which is an alpha for UIFlow 2.

Firmware options for the M5StampC3

To install the firmware on an S3 Based device you first plug one end of the USB>USBC cable into a computer port and then while holding the button on the front of the M5StampS3, Plug the USBC end into the M5Stamp S3. If you have time the button press correct, you will see a message pop up in the top right showing that the M5StampS3 has been detected at the port adress given in the box (see Image)

Click yes and you will be shown the M.A.C address that is printed on the lable and given the option to name the device. I recommend you take this change to name it something short and memorable instead of random characters. Click on Ok and M5Burner will either start burning the new firmware or return you to the main screen when you can click on the Burn button and then click on burn to write the firmware. Once the firmware is finished, wait for the message saying restarting and then close M5Burner.
