1# STM32 dual-bank flash Bootloader
2
3## Overview
4
5This bootloader leverages `embassy-boot` to interact with the flash.
6This example targets STM32 devices with dual-bank flash memory, with a primary focus on the STM32H747XI series.
7Users must modify the `memory.x` configuration file to match with the memory layout of their specific STM32 device.
8
9Additionally, this example can be extended to utilize external flash memory, such as QSPI, for storing partitions.
10
11## Memory Configuration
12
13In this example's `memory.x` file, various symbols are defined to assist in effective memory management within the bootloader environment.
14For dual-bank STM32 devices, it's crucial to assign these symbols correctly to their respective memory banks.
15
16### Symbol Definitions
17
18The bootloader's state and active symbols are anchored to the flash origin of **bank 1**:
19
20- `__bootloader_state_start` and `__bootloader_state_end`
21- `__bootloader_active_start` and `__bootloader_active_end`
22
23In contrast, the Device Firmware Upgrade (DFU) symbols are aligned with the DFU flash origin in **bank 2**:
24
25- `__bootloader_dfu_start` and `__bootloader_dfu_end`
26
27```rust
28__bootloader_state_start = ORIGIN(BOOTLOADER_STATE) - ORIGIN(**FLASH**);
29__bootloader_state_end = ORIGIN(BOOTLOADER_STATE) + LENGTH(BOOTLOADER_STATE) - ORIGIN(**FLASH**);
30
31__bootloader_active_start = ORIGIN(ACTIVE) - ORIGIN(**FLASH**);
32__bootloader_active_end = ORIGIN(ACTIVE) + LENGTH(ACTIVE) - ORIGIN(**FLASH**);
33
34__bootloader_dfu_start = ORIGIN(DFU) - ORIGIN(**DFU**);
35__bootloader_dfu_end = ORIGIN(DFU) + LENGTH(DFU) - ORIGIN(**DFU**);
36```
37
38## Flashing the Bootloader
39
40To flash the bootloader onto your STM32H747XI device, use the following command:
41
42```bash
43cargo flash --features embassy-stm32/stm32h747xi-cm7 --release --chip STM32H747XIHx
44```
