The GigaDevice GD32E1 series are 32-bit general-purpose microcontrollers based on the ARM Cortex-M4 processor.

On-Chip Memory Regions

The internal flash is divided into 4 different regions:

  • Main Flash Block (0x08000000 - 0x0801FFFF)
  • Information Block (0x1FFFB000 - 0x1FFFF7FF)
  • Option bytes Block (0x1FFFF800 - 0x1FFFF80F)
  • One-time program Block (0x1FFF7000 - 0x1FFF71FF)

For now, the Main Flash Block is supported, only.

Vector Table Remap

The first 512 bytes of the device (0x0000 - 0x01FF) can be mapped to flash, ROM or RAM. When using the J-Link flashloader, this region is mapped to flash. This is done on purpose as the device does not provide a mirror address for the first 512 bytes of flash thus without remapping, the J-Link could not program the first 512 bytes.

Reset

No special reset is required.
