This is my first time flash the STM32,with the ebastler E80-1800
but the author`s guide is very simple
after learned how to flash it and succeed,
I record the progress for newb or anyone make the ebastler E80 may need it
Platform: Windows 11 22H2 ver 22621.674
Build Environment: QMK MSYS ver 1.72
Flash Software: QMK Toolbox ver 0.2.2
PCB rev: 1.2
MCU: STM32F072RBT6
After installed QMK Toolbox,you have to install the drivers in the "Tools" menu

2. Connect the keyboard to PC
According to the author`s guide
No pre-flashed firmware, option 1: Bridge BOOT labeled pads below spacebar while plugging the board in
then in the QMK Toolbox you will see STM32 Bootloader connect in yellow font
and in the Windows Device Manager there will be a new device named "STM32 BOOTLOADER"
3.Install QMK MSYS and build environment
Follow the build environment setup
Do a test to verify the environment,in the QMK MSYS window,input the command:
$ qmk compile -kb lets_split -km default
successfully you will see a lot of [OK] in green font
4.Compile the E80-1800 firmware
Input the command in the QMK MSYS window:
$ qmk compile -kb ebastler/E80-1800 -km default
you will get 4 files in your C:\Users\<username>\qmk_firmware\\.build

5.Flash the firmware
Back to the QMK Toolbox
Press the open button and select the file: ebastler_e80_1800_default.bin, not the .hex file
MCU drop down leave it default or select the ATmega32U4
And press "Flash"
This step according to the [Guide] Flashing Planck Rev6 or STM32 PCB on Windows
Finsh!
PS.My english is not good,hope you can read it and success!
