+# STM32 dual-bank flash Bootloader
+
+## Overview
+
+This bootloader leverages `embassy-boot` to interact with the flash. 
+This example targets STM32 devices with dual-bank flash memory, with a primary focus on the STM32H747XI series. 
+Users must modify the `memory.x` configuration file to match with the memory layout of their specific STM32 device.
+
+Additionally, this example can be extended to utilize external flash memory, such as QSPI, for storing partitions.
+
+## Memory Configuration
+
+In this example's `memory.x` file, various symbols are defined to assist in effective memory management within the bootloader environment.  
+For dual-bank STM32 devices, it's crucial to assign these symbols correctly to their respective memory banks. 
+
+### Symbol Definitions
+
+The bootloader's state and active symbols are anchored to the flash origin of **bank 1**:
+
+- `__bootloader_state_start` and `__bootloader_state_end`
+- `__bootloader_active_start` and `__bootloader_active_end`
+
+In contrast, the Device Firmware Upgrade (DFU) symbols are aligned with the DFU flash origin in **bank 2**:
+
+- `__bootloader_dfu_start` and `__bootloader_dfu_end`
+
+```rust
+__bootloader_state_start = ORIGIN(BOOTLOADER_STATE) - ORIGIN(**FLASH**);
+__bootloader_state_end = ORIGIN(BOOTLOADER_STATE) + LENGTH(BOOTLOADER_STATE) - ORIGIN(**FLASH**);
+
+__bootloader_active_start = ORIGIN(ACTIVE) - ORIGIN(**FLASH**);
+__bootloader_active_end = ORIGIN(ACTIVE) + LENGTH(ACTIVE) - ORIGIN(**FLASH**);
+
+__bootloader_dfu_start = ORIGIN(DFU) - ORIGIN(**DFU**);
+__bootloader_dfu_end = ORIGIN(DFU) + LENGTH(DFU) - ORIGIN(**DFU**);
+```
+
+## Flashing the Bootloader
+
+To flash the bootloader onto your STM32H747XI device, use the following command:
+
+```bash
+cargo flash --features embassy-stm32/stm32h747xi-cm7 --release --chip STM32H747XIHx
+```
