4.2 Memory Allocation

The main Flash memory is divided into three parts:

LFU bootloader:

The first 16 KB (0x0000 - 0x3FFF) of main flash memory is reserved for LFU bootloader, the other main flash space is assigned to application code.

Application code:

This memory space is divided into application space 1 and application space 2, only one version of application code is executed, the other application code space is used for new firmware upgrade purpose.

The first 4 KB (0x2020000 - 0x20200FFF) of RAM space is reserved for bootloader and the other memory space can be used for application code.
