Walkthrough

Two new configuration header files are introduced for the GDSTARTF425 and GDSTARTF460 flight controller boards. Each file defines board-specific macros for MCU target, sensor and peripheral support, pin assignments, timer mappings, ADC/UART/I2C/SPI settings, and default device configurations for integration with Betaflight firmware.

Changes

File(s) Change Summary
configs/GDSTARTF425/config.h, configs/GDSTARTF460/config.h Added new configuration headers for GDSTARTF425 and GDSTARTF460 boards, defining MCU, sensor, peripheral, pin, timer, ADC, UART, I2C, SPI, and default device macros.

Learning: In Betaflight configurations, when a target name suggests dual IMUs (like JHEF7DUAL) but specific hardware variants only have one gyro available, the preferred solution is to use DEFAULT_GYRO_TO_USE macro to specify which gyro to use by default rather than pruning gyro defines or creating redundant configurations. This approach maintains compatibility when the same target is used by multiple hardware variants from the same manufacturer.

Learning: In STM32F405-based flight controller configurations, timer pin mappings must be carefully analyzed for DMA stream conflicts, especially between motor timers, LED strip timers, and SPI DMA assignments. Changes to TIMER_PIN_MAPPING should include verification that all required peripherals (motors, LED strip, blackbox SPI) can coexist without DMA conflicts.

Learning: Always verify that the `BOARD_NAME` define in config.h files exactly matches the directory name where the config file is located. For example, if the config file is in configs/AXISFLYINGF7AIO/config.h, then the BOARD_NAME should be defined as "AXISFLYINGF7AIO". This ensures proper board identification and configuration loading in Betaflight.

Learning: In Betaflight configuration files, USE_OSD_HD and USE_MAX7456 are for different OSD systems: USE_MAX7456 enables the MAX7456 analog OSD chip, while USE_OSD_HD enables HD/digital OSD via MSP. MSP_DISPLAYPORT_UART should be guarded by USE_OSD_HD, not USE_MAX7456, as they serve different OSD implementations.

🔇 Additional comments (9)
configs/GDSTARTF425/config.h (4)

26-26: BOARD_NAME matches directory structure correctly.

The BOARD_NAME definition correctly matches the directory name where this config file is located.


30-42: Sensor support configuration looks comprehensive.

The sensor support configuration enables appropriate gyroscope, accelerometer, barometer, flash, and OSD device support for a modern flight controller.


97-107: Timer pin mapping configuration appears consistent.

The timer pin mapping defines appropriate timer channels for motor outputs, PPM input, and LED strip control. The mapping follows standard Betaflight conventions.


118-134: Default configurations are appropriate for the target hardware.

The default device configurations include appropriate settings for blackbox logging, DShot protocol, ADC sources, and peripheral assignments that align with the hardware capabilities.

configs/GDSTARTF460/config.h (5)

26-26: BOARD_NAME matches directory structure correctly.

The BOARD_NAME definition correctly matches the directory name where this config file is located.


29-41: Sensor support configuration matches F425 variant appropriately.

The sensor support configuration is consistent with the F425 variant, enabling the same comprehensive set of sensors for flight controller functionality.


71-79: SPI pin assignments differ from F425 variant.

The SPI pin assignments for this board differ from the F425 variant:

  • SPI0: PA5/PA6/PA7 (vs PB3/PB4/PB5 on F425)
  • SPI2: PB3/PB4/PB5 (vs PC10/PC11/PC12 on F425)

This suggests different PCB routing between the two board variants, which is expected for different MCU packages.


115-132: Default configurations are consistent with F425 variant.

The default device configurations are appropriately consistent with the F425 variant, maintaining the same peripheral assignments and protocol settings.


94-104: Confirm timer pin mapping consistency with GD32F425 variant

I wasn’t able to find a GD32F425 config header in configs/ to compare mappings directly. Please verify that the following timer-capable pins on the GD32F460:

PA3, PC6, PC7, PC8, PC9, PA15, PA8, PB10, PB11, PB1

match the intended mappings on the GD32F425, especially since SPI pin assignments differ.

• File: configs/GDSTARTF460/config.h (lines 94–104)
• Pins to verify: PA3, PC6, PC7, PC8, PC9, PA15, PA8, PB10, PB11, PB1
