Example description
===================
This example shows how to use the external SRAM mounted on STM3210E-EVAL board as
program data memory and internal SRAM for Stack.
Directory contents
==================
stm32f10x_conf.h Library Configuration file
stm32f10x_it.c Interrupt handlers
stm32f10x_it.h Header for stm32f10x_it.c
main.c Main program
stm32f10x_vector.s STM32F10x vector table for RVMDK toolchain.
Hardware environment
====================
This example runs on STMicroelectronics STM3210E-EVAL evaluation board.
How to use it
=============
In order to make the program work, you must do the following:
- Create a project and setup all your toolchain's start-up files:
+ RVMDK
- in Project->Options->Target window, select 'RAM1'and enter 0x68000000 as
start address with size of 0x100000 (IRAM1 must be un-checked)
- use the "stm32f10x_vector.s" provided within this example directory
+ EWARM4
- use "lnkarm_flash_extsram.xcl" as linker file
- uncomment "#define DATA_IN_ExtSRAM " in the "stm32f10x_vector.c" file
+ EWARM5
- use "stm32f10x_flash_extsram.icf" as linker file
- uncomment "#define DATA_IN_ExtSRAM " in the "stm32f10x_vector.c" file
+ RIDE
- In the Application options -> script menu, set "Use Default Script File"
to "No" and use "stm32f10x_flash_extsram.ld" as Script File.
- uncomment "#define DATA_IN_ExtSRAM " in the "stm32f10x_vector.c" file
+ HiTOP
- in project->settings->project->tool settings->linker, use "linkextsram"
as linker file. With this linker, the external SRAM is used for both
program data and Stack.
- in cstart_thum2.asm file, change "DATA_IN_ExtSRAM .equ 0"
by "DATA_IN_ExtSRAM .equ 1"
- Compile the directory content files and required Library files:
+ stm32f10x_lib.c
+ stm32f10x_gpio.c
+ stm32f10x_rcc.c
+ stm32f10x_nvic.c
+ stm32f10x_flash.c
+ stm32f10x_fsmc.c
- Link all compiled files and load your image into target memory
- Run the example
