The following files are firmware for the OMGS3.
Program your board using the latest version of the esptool.py program, found here.
To flash or erase your OMGS3, you have to first put it into download mode. OMGS3 doesn't include buttons for RESET and IO0, which should be provided by adding external buttons via a carrier board or other method. To put the OMGS3 into download, follow these steps:
Now the board is in download mode and the native USB will have enumerated as a serial device.
If you are putting MicroPython on your board for the first time then you should first erase the entire flash using:
esptool.py --chip esp32s3 --port /dev/ttyACM0 erase_flash
Please do a ls /dev/cu.usbm*
to determine the port your board has enumerated as.
esptool.py --chip esp32s3 --port /dev/cu.usbmodem01 erase_flash
Change (X) to whatever COM port is being used by the board
esptool --chip esp32s3 --port COM(X) erase_flash
Now download the version of the firmware you would like to install from the options below,
then use the following command to program the firmware starting at address 0x0,
remembering to replace omgs3-micropython-firmware-version.bin
with the name of
the firmware you just downloaded:
esptool.py --chip esp32s3 --port /dev/ttyACM0 write_flash -z 0x0 omgs3-micropython-firmware-version.bin
Please do a ls /dev/cu.usbm*
to determine the port your board has enumerated as.
esptool.py --chip esp32s3 --port /dev/cu.usbmodem01 write_flash -z 0x0 omgs3-micropython-firmware-version.bin
Change (X) to whatever COM port is being used by the board
esptool --chip esp32s3 --port COM(X) write_flash -z 0x0 omgs3-micropython-firmware-version.bin
