Firmware Guide¶

Download Vscode + platformio¶

To compile the firmware , you need to install Visual Studio Code and the platformio pulg-in.

Download firmware¶

You can download the firmware from https://github.com/FYSETC/Marlin-2.0.x-FYSETC , and if you want to know what we have changed , we recommend to use git to get the code .

The firmware you download is for Cheetah board in default，you need copy the configuration.h & configuration_adv.h from config/Fysetc/AIO_II to the marlin folder.

The latest configurations are in separate repository here, you can download and find the config in config/Fysetc/AIO_II folder

Compile the firmware¶

Open Vscode and open platformio main page and click the "Open Project" button , and direct to the folder where you put your firmware.

If everything goes fine , at the bottom you can see several buttons

The check mark is for compiling .

Open platformio.ini file and change the option default_envs as below.

default_envs = fysetc_STM32F1

And then replace the default configuration.h and configuration_adv.h with files locate in FIRMWARE_LOCATE\Marlin\Marlin\config\examples\FYSETC according to your board.

Then click check mark to compile.

If you can't generate the hex file, you may need to open vscode using Administrator Account .

For more detail information，you can refer to http://marlinfw.org/docs/basics/install_platformio.html

Upload the firmware(windows,linux,Mac)¶

We provide several ways to upload the firmware .You can just click the upload button to upload the firmware or refer to the two methods below.

Upload the firmware(windows)¶

After compiling , you should see the firmware file "firmware.hex" in the folder FIRMWARE_LOCATE\Marlin\Marlin\.pioenvs\fysetc_STM32F1\

Download the flash software in our github https://github.com/FYSETC/STM32Flasher

Connect the board and your pc with USB cable (This step should before you open the software)

Double the click "FlyMcu.exe" software to open it.

1. Select "Reset@DTR low(<-3v),ISP @RTS High"
2. Click "Port" to select the port of your USB
3. Select FIRMWARE_LOCATE\Marlin\Marlin\.pioenvs\fysetc_STM32F1\firmware.hex as the screenshot shows.
4. At last ,click the "Start ISP(p)" to upload the firmware.

Upload the firmware(linux)¶

Load usb driver¶

Delete the old version driver /lib/modules/$(uname -r)/kernel/drivers/usb/serial/ch341.ko

rm /lib/modules/$(uname -r)/kernel/drivers/usb/serial/ch341.ko

Download the CH34x driver(linux version) from our github

https://github.com/FYSETC/CH340-Driver

follow the readme.txt to make and load the driver .

If you want the driver load automatically every time your PC power up. You can copy the ch34x.ko file to

directory /lib/modules/$(uname -r)/kernel/drivers/usb/serial/ , and do

depmod 

Install stm32flash tool¶

First get the code

git clone https://git.code.sf.net/p/stm32flash/code stm32flash-code

Then follow the INSTALL file to install the software

Upload the firmware¶

Connect the motherboard with USB cable and your PC. And do

dmesg

And you will get message like

the ttyUSB0 is the port to communicate with the motherboard.

And then go the the firmware.hex file location directory and do the follow command to upload the firmware

 stm32flash -w firmware.hex -v -i rts,-dtr /dev/ttyUSB0
