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](https://github.com/MarlinFirmware/Configurations/tree/bugfix-2.0.x), 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. ![1561099422559](https://raw.githubusercontent.com/FYSETC/wiki.fysetc/main/docs/images/crisp/AIO_f1.png) If everything goes fine , at the bottom you can see several buttons ![1561099546202](https://raw.githubusercontent.com/FYSETC/wiki.fysetc/main/docs/images/crisp/AIO_f2.png) 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. ![1561100540118](https://raw.githubusercontent.com/FYSETC/wiki.fysetc/main/docs/images/crisp/AIO_f3.png) 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 ![1562654867797](https://raw.githubusercontent.com/FYSETC/wiki.fysetc/main/docs/images/crisp/AIO_f4.png) 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 ``` ## Attachments ------ - [Schematic files](https://github.com/FYSETC-AIO_II/) - [PCB files](https://github.com/FYSETC/FYSETC-AIO_II/) - [2D and 3D drawings](https://github.com/FYSETC/FYSETC-AIO_II/) ## Where to Buy ------ - [FYSETC AIO II V3.1](https://www.aliexpress.com/item/32888370577.html) ## Tech Support ------- For some reason,, we have to access Facebook via VPN...so our engineers can't reply to your question on Facebook in time, if possible, please ask questions in the forum. **Please submit any technical issue into our [forum](http://forum.fysetc.com/)** .
