@Fly3DTeam Why are you not adding the Fly D8 Pro?

That's great, well done. It's probably best for most users to link to the English pages.

The schematic given for the Fly D8 Pro (STM32H723) is wrong, it's the schematic of the D8 (STM32F407).

I had a quick look at the D9 Pro pinout, it seems correct except for the temperature section:

// Temperature Sensors
#define TEMP_0_PIN                          PC2   // Analog Input
#define TEMP_1_PIN                          PC3   // Analog Input
#define TEMP_2_PIN                          PC5   // Analog Input
#define TEMP_BED_PIN                        PB0   // Analog Input

#define TEMP_3_PIN                          PC3   // Analog Input
#define TEMP_4_PIN                          PC5   // Analog Input

You could also add the FDCAN pins:

#define FDCAN_RX           PB8
#define FDCAN_TX           PB9

You can define the driver UART and SPI pins like this:

#define X_STEP_PIN                          PE5
#define X_DIR_PIN                           PA8
#define X_ENABLE_PIN                        PA15
#if AXIS_HAS_SPI(X)
  #define X_CS_PIN                          PC9
#endif
#if AXIS_HAS_UART(X)
  #define X_SERIAL_RX_PIN                   PC9
  #define X_SERIAL_RX_PIN       X_SERIAL_TX_PIN
#endif

Is there a bootloader to flash the Marlin firmware via a USB stick in one of the USB ports?
Most boards can flash via a onboard SD Card slot, but the D8 Pro doesn't have one, using the onboard USB port would be even more user friendly.

A schematic diagram shared by D8 and D8PRO. Because the 100-pin chip of F4 is slightly different from that of H7, please refer to the pin diagram in the documentation manual.
The USB-A port on the D8 motherboard has no function in Marlin.
D8 can only be burned using the DFU of typr-c.

Ok, thanks for the reply, DFU will always work, USB firmware flashing would be very appreciated by many users.

I see a few issues in the variant board definition.
Flashing Marlin will overwrite the Catapult bootloader, that's not needed. Marlin could be loaded at 0x08020000, and let Catapult jump to it.

board_build.offset          = 0x20000
board_upload.offset_address = 0x08020000

and enable the FDCAN port (add to build_flags):
-DHAL_FDCAN_MODULE_ENABLED
I also noticed that lots of devices are disabled in PeripheralPins.c. Marlin needs this information to find the devices as defined in the pins definition. By disabling the devices the capabilities of the board are reduced. FDCAN, I2C and Ethernet are completely disabled, and there is only one USART enabled, which is LPUART1. LPUART1 is not accessibly by the DMA1/2 controllers, so the DMA serial features will not work. It would be nice if all devices that are accessible on the board, and are not conflicting with the hardware could be accessed.

The given pinout for D8 Pro EXT1 and EXT2 connectors seem to be wrong.

How about this:

(FLY D8 PRO EXT1 EXT2 PINOUT)

So I guess the FLY D8 pinout is also wrong:

I tried to compile Marlin based on the provided files for the Fly D8 Pro and Fly Super 8 Pro. Both configurations cannot compile.
Have these configurations been tested?

I set the serial ports correctly before compilation, that is not the cause of the compilation error.
Also the previously mentioned peripheral issues have not been fixed, so even if the code compiles, the board cannot work properly. This needs more testing.

Thanks for correcting the EXP port pinouts. Unfortunately the D8 PRO EXP1 still has an obvious mistake, at least if I check it on a D8 Pro V1.1, perhaps it's correct for a V1.0 board.

[rondlh]

The Fly D8 Pro configuration does not work well, it needs actual testing. Compilation doesn't work, even when the compilation issues are fixed the configuration has clear issues related to the device configuration and available peripherals.

[rondlh]

Commenting out almost all devices makes them inaccessible for Marlin, like for example the CAN bus and serial ports.
With this configuration only the LPUART1 serial port is available, which will not work with feature like SERIAL_DMA.
It recommend to leave all devices that do no have hardware conflicts on the board enabled.

The D8 Pro configuration does not work well. Lot's of issues, needs testing...

D5/DP5/D7, Currently, the UART mode of TMC cannot be used.

Does the SPI mode for TMC work?

What's the reason UART mode for TMC doesn't work?
