Bootloader for Quansheng UVK5 Firmware Switching (UNTESTED)

• 3 firmware Multiboot with independent settings, channels and calibrations for 256 KiB EEPROM
• 4 firmware Multiboot with independent settings, channels and calibrations for 512 KiB EEPROM
• 6 firmware Multiboot with independent settings, channels and calibrations for 512 KiB EEPROM

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.
• Also reading configs for each firmware and put on top of EEPROM. And replace it while firmware change.

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

• This bootloaders suitable for UVK5 with 2M (256KiB) and 4M (512KiB) 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

• Use https://github.com/Sobollion/R9OOT_BOOT on windows or run it with python on other OS.
• LOSEHU_BASE_BOOT is the base bootloader used to replace the official Quansheng bootloader. You can make it with Keil.
• The bootloader file BL_3_XXX.bin/BL_4_XXX.bin/BL_6_XXX.bin generated after running make in the main directory is stored in EEPROM and loaded into RAM by the base bootloader.
• BL_X_XXX.bin performs functions such as serial port firmware flashing and firmware switching. NEED TO DEBUG!
