2. RAM Structure

Note: Boot and App share the same RAM area and occupy their corresponding spaces during different runtime stages.

Start Address	End Address	Region Name	Size	Function Description
0x20000000	0x20001FFF	Boot	8 KB	Used during the boot stage for buffering and variable storage
0x20000000	0x20001FFF	App	8 KB	Used during application runtime for task stacks, variables, and caching

3. Detailed Description

Boot Area (6 KB)
Used to store the bootloader and firmware upgrade control logic.
The last byte stores the firmware version number for version management and upgrade validation.
App Area (56 KB)
Used to store the user application program.
The last 4 bytes are reserved for CRC checksum storage. The bootloader verifies the program before loading.
The verification uses the standard CRC‑32 algorithm (IEEE 802.3, polynomial 0x04C11DB7, initial value 0xFFFFFFFF, input/output reflected, result bitwise inverted, and stored in little‑endian byte order).
Reserved Area (1 KB)
Used to store system parameters.
