This article describes device specifics of the ST STM32F2 series devices. The STM32F2 devices are Cortex-M3 based MCUs with low-power functionality.
Internal Flash
The following flash regions are supported by J-Link.
| Device | Range | Total size |
|---|---|---|
| STM32F2xxxB | 0x0800_0000 - 0x0801_FFFF | 128 KB |
| STM32F2xxxC | 0x0800_0000 - 0x0803_FFFF | 256 KB |
| STM32F2xxxE | 0x0800_0000 - 0x0807_FFFF | 512 KB |
| STM32F2xxxF | 0x0800_0000 - 0x080B_FFFF | 768 KB |
| STM32F2xxxG | 0x0800_0000 - 0x080F_FFFF | 1024 KB |
| All (opt. bytes) | 0x1FFF_C000 - 0x1FFF_C00F | 16 bytes |
Reset
For the STM32F2 devices, the Cortex-M default reset strategy is used.
Debug specific
Please refer to the general STM32 article
Securing/unsecuring the device
Please refer to the related article here.
