4. Firmware Guide¶

Spider support Marlin firmware, Klipper firmware and RRF firmware. Choose one you need.

4.1 Marlin¶

4.1.1 Download Vscode + platformio¶

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

4.1.2 Download firmware¶

The Marlin firmware is in the firmware/Marlin folder in this repository , you can also get the firmware from latest Marlin bugfix-2.0.x branch. You need to enable following define in configuration.h file

#define MOTHERBOARD BOARD_FYSETC_SPIDER
#define SERIAL_PORT -1

Then we need to change platformio.ini file

default_envs = FYSETC_S6 (For old bootloader,boot address is 0x10000, see below)

default_envs = FYSETC_S6_8000 (For new bootloader,boot address is 0x8000, see below)

Note: The bootloader boot address have been change to 0x08008000 since 2021/06/23, you can check bootloader details github or gitee, and you can check the Marlin PR here.

4.1.3 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 , click it to compile. You can find built firmware.bin at .pio\build\FYSETC_S6 or .pio\build\FYSETC_S6_8000 folder.

4.1.4 Upload firmware¶

Follow Firmware Update guide here.

4.2 Klipper¶

We put Klipper related files like printer.cfg in firmware/Klipper folder in this repo. Please read the README there.

If you want to use Klipper. You need to follow the Klipper installation guide to install Klipper first. When we try to compile it, we need to call make menuconfig to choose compile options, please select options for Spider as below describe.

4.2.1 menuconfig¶

Please choose these options for Spider, you need to decide which to choose according to your board and wiring on some options.

• Enable extra low-level configuration options¶

• Micro-controller Architecture¶

Select STMicroelectronics STM32

• Processor model¶

Select STM32F446

• Clock reference¶

Select 12 MHz crystal

• Bootloader offset¶

• 32KiB bootloader¶

If you choose 32kiB bootloader offset in Klipper make menuconfig. Then you need to flash the spider board bootloader named Bootloader_FYSETC_SPIDER first(If you get your Spider board after 2021/06/23, no worries, the bootloader is on the board when it leave the factory, if not, flash it first). The bootloader is in the folder named bootloader in this repo, please follow the README in bootloader folder(github or gitee) to flash the bootloader. We provide pre-build firmwares with 32KiB bootloader named klipper-32k-USB.bin and klipper-32k-UART.bin for you,find them here github gitee. These pre-build firmware will be outdated if Klipper update and will not match your new downloaded Klipper and cause annoying issues. We will try to catch up with Klipper, but i recommend to build the firmware yourself.

• Communication interface¶

You have two choices here, if you use USB cable to connect RaspeberryPI and Spider, you need to check 1. USB (on PA11/PA12). If you use serial to connect RaspberryPI and Spider, then check 2. Serial (on USART1 PA10/PA9).

• 1. USB (on PA11/PA12)¶

If you want to connect Spider to RaspberryPI with USB cable. You need to select USB (on PA11/PA12)

And in printer.cfg you need to set the serial as below. We provide an example cfg file printer.cfg for VORON 2 machine here.

Obtain definition by "ls -l /dev/serial/by-id/" then unplug to verify
##--------------------------------------------------------------------
serial: /dev/serial/by-id/usb-Klipper_stm32f446xx_230032000851363131363530-if00

• 2. Serial (on USART1 PA10/PA9)¶

If you want to connect Spider UART1(RX1:PA10, TX1:PA9) port to RPI uart0(TX:GPIO14,RX:GPIO15) port, you need to select Serial (on USART1 PA10/PA9)

In printer.cfg you need to uncomment the following line as our example printer.cfg file here (github gitee)do, if your cfg file don't have this line, please add it.

serial: /dev/ttyAMA0

Besides this make option, you still need to follow the instructions that Connect RPI uart.md file says, you can find the file github or gitee.

3. CAN bus (on PD0/PD1)¶

You need to follow Klipper CANBUS instruction here CANBUS - Klipper documentation after you compiled and upload the firmware.

4.2.2 Compile firmware¶

make

4.2.3 Upload firmware¶

Follow Firmware Update guide here.

4.3 RRF¶

As RRF firmware requires more than 512KB of Flash space, the Spider equipped with 446 cannot meet its requirements. So it needs to disable some features to make it work, please check the README in firmware/RRF folder github gitee.

4.4 Firmware Upload¶

We provide several ways to upload the firmware including SDCARD, dfu-util, DFU and platformio.

4.4.1 Upload the firmware(SDCARD)¶

Uploading firmware using SD card is our default way to update the firmware as Spider already has the bootloader in it when it leave the factory. But if you once upload the firmware to Spider flash address 0x08000000, then the bootloader in Spider will be gone, then you need to upload the bootloader to Spider yourself, please follow the README in bootloader folder (github or gitee) to upload the bootloader.

Uploading firmware using SD card: copy your compiled firmware file firmware.bin(If you use klipper firmware, you need to rename klipper.bin to firmware.bin) file to the SD card , and insert it to the SD card slot which is at the right side of the board, and then power up the board. You may need to wait for about 30s to finish uploading, there is LED beside the sdcard slot blinking when it is uploading.

4.4.2 Upload the firmware(dfu-util)¶

This method works in linux, that means should work in raspberry pi.

Step 1. Enter DFU mode first¶

1. First power off the board

2. Set jumper on 5V pin and DC5V

3. Place jumper on BT0 to 3.3V pin

4. Connect USB cable to the board and your computer

5. Power up the board with 24v

Now the board is in DFU mode. If not, click the reset button. Also you can power on the board with 5v, but you need to set jumper on 5V and USB5V (Check the silkscreen lable on the back of the board) but not on 5V and DC5V.

REMEMBER to remove BT0 jumper if you finish uploading firmware or it will enter DFU mode again.

Step 2. Install dfu-util¶

Make sure dfu-util is installed, shoot dfu-util --version command to check.

Sample output:

dfu-util 0.9

Please report bugs to http://sourceforge.net/p/dfu-util/tickets/

If not , you should install it first, use the package manager of your distribution to get the latest version, like

sudo apt-get install dfu-util

Step 3. Use command to upload firmware¶

Then use the command below to upload the firmware. You should replace firmware.bin below with your built firmware bin(or hex) file location like out/klipper.bin. Change flash address 0x08008000 to bootloader you choosed. (If you use Marlin firmware and your platformio env is default_envs = FYSETC_S6, then you need to set it to 0x08010000, if env is default_envs = FYSETC_S6_8000, then you need to set it to 0x08008000 . If you use klipper firmware and you choose boot address No bootloader when compiling then set it 0x08000000, if 32kiB bootloader , set it 0x08008000. if 64KiB bootloader set it to 0x08010000.If yours is hex file, set it 0x08000000).

dfu-util -R -a 0 -s 0x08008000:leave -D firmware.bin

4.4.3 Upload the firmware(DFU)¶

The other way to upload the firmware is using DFU.

Step 1. Download stm32cubeprogrammer¶

You can download it from ST website.

https://www.st.com/zh/development-tools/stm32cubeprog.html

Open the STM32CubeProgrammer software.

Step 2. Enter DFU mode¶

1. First power off the board
2. Set jumper on 5V pin and DC5V
3. Place jumper on BT0 to 3.3V pin
4. Connect USB cable to the board and your computer
5. Power up the board with 24v

Now the board is in DFU mode. If not, click the reset button. Also you can power on the board with 5v, but you need to set jumper on 5V and USB5V (Check the silkscreen lable on the back of the board) but not on 5V and DC5V.

REMEMBER to remove BT0 jumper if you finish uploading firmware or it will enter DFU mode again.

Step 3. Upload the firmware¶

Now you can connect and flash the Spider board with stm32cubeprogrammer with the following operation.

Do as the red number shows in the screen shot.

1. Click the button to find the DFU port.
2. Connect the DFU
3. Choose the "firmware.bin" file. (or .hex file).
4. Fill in the 'Start address' (If you use Marlin firmware and your platformio env is default_envs = FYSETC_S6, then you need to set it to 0x08010000, if env is default_envs = FYSETC_S6_8000, then you need to set it to 0x08008000 . If you use klipper firmware and you choose boot address no bootloader when compiling then set it 0x08000000, if 32kiB bootloader , set it 0x08008000. if 64KiB bootloader set it to 0x08010000. If yours is hex file, don't need to set anything).
5. Start Programming

4.4.4 Upload the firmware(platformio)¶

If you compile Marlin yourself with platformio,you can follow the instructions below to upload the firmware.

Step 1. Enter DFU mode first¶

• First power off the board

• Set jumper on 5v pin and DC5V

• Place jumper on BT0 to 3.3V pin

• Connect USB cable to the board and your computer

• Power up the board with 24v

Now the board is in DFU mode. If not, click the reset button. Also you can power on the board with 5v, but you need to set jumper on 5V and USB5V (Check the silkscreen lable on the back of the board) but not on 5V and DC5V.

REMEMBER to remove BT0 jumper if you finish uploading firmware or it will enter DFU mode again.
