GigaDevice GD32E1
Contents
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 and the Option bytes Block, 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.
