REFER HOST APPLICATION

BOOTLOADER NOTE START:

Step #1 The RAM & FLASH LENGTH are different for each ChipSet of ST. So refer data sheet modify as per your need's

PROJECT DETAILS:

Project name: BOOTLOADER

ChipSet Name: STM32F030RCT6

		RAM: 32K

	  FLASH: 256K

SOFTWARE DETAILS:

		 IDE: STM32CUBEIDE

BootLoader Size: 20K Application Size: 256K - 20K

Step #2 Based On "Step #1" Details & Modify Below Section and Update into Linker File Script

 /* Memories Definition */
MEMORY
{
  RAM    		(xrw)   : ORIGIN = 0x200000C0,   LENGTH = 32K - 192 /* 192 For Vector Table Relocate */
  BOOTLOADER	(rx)    : ORIGIN = 0x8000000,   LENGTH = 20K
  /*FIRMWARE		(rx)    : ORIGIN = 0x8005000,   LENGTH = 256K - 20K*/
}
/* Main App Start Symbol */
_main_app_start_address = 0x08005000;

/* For Main Application, change BOOTLOADER by FIRMWARE */
REGION_ALIAS("FLASH", BOOTLOADER );

Step #3 Call "BL_JumpToApp" in Main after the Driver initialization

FIRMWARE NOTE START:

Step #1 The RAM & FLASH LENGTH are different for each ChipSet of ST. So refer data sheet modify as per your need's

Step #2 Based On "Step #1" Details & Modify Below Section and Update into Linker File Script

 /* Memories Definition */
MEMORY
{
  RAM    		(xrw)   : ORIGIN = 0x200000C0,   LENGTH = 32K - 192 /* 192 For Vector Table Relocate */
  /*BOOTLOADER	(rx)    : ORIGIN = 0x8000000,   LENGTH = 20K*/
  FIRMWARE		(rx)    : ORIGIN = 0x8005000,   LENGTH = 256K - 20K
}
/* Main App Start Symbol */
_main_app_start_address = 0x08005000;

/* For Main Application, change BOOTLOADER by FIRMWARE */
REGION_ALIAS("FLASH", FIRMWARE );

Step #3 Copy below variables in main.c as global vairables

extern uint32_t _main_app_start_address;

#define FIRMWARE_START_ADDR (uint32_t)(&_main_app_start_address)

Step #4 Call "Main_APP_Init " API in Before the Driver initialization. {For Reset vector table copying process}
