GD32F1 series selection
GD32F10x and GD32F1x0 devices share a Cortex-M3 core. Their package pinouts, peripherals and firmware configuration depend on the exact part number.
Compare the documented families
| Family | Check before wiring |
|---|---|
| GD32F103 | Separate pin definitions for each package, and multiple memory densities. The programming manual covers AFIO remaps. |
| GD32F130 | Separate alternate-function selections per pin and a different set of boot configuration options. Check the GPIO and SYSCFG chapters. |
Before bring-up
- Compare the exact number of Flash code and data bytes with the linker layout.
- Start with the package-specific supply, reset, BOOT0 and SWD connections. Verify any peripheral pin assignment before enabling it.
