Bootloader for Quansheng UVK5 Firmware Switching

Function Description

Capable of reading firmware from EEPROM and writing it to flash, allowing switching between different firmware versions.
Reads valid firmware from EEPROM and allows selection via button press for loading.

Principle Description

Rewrite the UV-K5 bootloader to load Bootloader B into RAM from EEPROM on startup, then jump to Bootloader B in RAM.
Bootloader B:
- Reads firmware from EEPROM and writes it to FLASH.
- Supports traditional burning communication protocols.

Requirements

Due to language requirements (Chinese input method), approximately 150KB is needed, so this bootloader is only suitable for UVK5 with 4Mib (512KB) EEPROM.
Due to flash size limitations, individual firmware size should not exceed 60KB.
Requires ST-Link to flash the new bootloader into UVK5's FLASH.

Instructions

Refer to the losehu Bootloader Manual.pdf in this directory.
LOSEHU_BASE_BOOT is the base bootloader used to replace the official Quansheng bootloader.
The bootloader file L_BLXXX.bin generated after running make in the main directory is stored in EEPROM and loaded into RAM by the base bootloader.
L_BLXXX.bin performs functions such as serial port firmware flashing and firmware switching.
