Solve MTK file system memory allocation problems

MTK file system memoryAllocation Problem Solving is the content to be introduced in this article, mainly to understand and learnMTK File SystemSo as to better manage and allocateMemoryAboutMTK File SystemFor more information, see this document.

MTK uses 64 x32 flash and is allocated by the 7 + 1 file system as follows:

The OPTION. MAK file is blocked because the flash_opt.h and custom_flash.c files are automatically generated.

 
 

  
  
FLASH_OPTIONS_HDR =#$ (strip $ (FIXPATH) \ custom \ system \ $ (strip $ (BOARD_VER) \ flash_opt.h and
  
  
CUSTOM_FLASH_C =#$ (strip $ (FIXPATH) \ custom \ system \ $ (strip $ (BOARD_VER) \ custom_flash.c
