If the access is not permitted, +a memory management fault is generated and LED2 is ON. +To generate an MPU memory fault exception due to an access right error, uncomment +the following line "privilegedreadonlyarray[0] = 'e';" in the +"accesspermission.c " file. + +@par Directory contents + + - CortexM3/MPU/stm32f10x_conf.h Library Configuration file + - CortexM3/MPU/stm32f10x_it.c Interrupt handlers + - CortexM3/MPU/stm32f10x_it.h Header for stm32f10x_it.c + - CortexM3/MPU/main.c Main program + - CortexM3/MPU/system_stm32f10x.c STM32F10x system source file + - CortexM3/MPU/accesspermission.c Cortex-M3 MPU regions Access rights file + +@par Hardware and Software environment + + - This example runs on STM32F10x XL-density Devices. + + - This example has been tested with STMicroelectronics STM3210E-EVAL (High-Density + and XL-Density) evaluation board and can be easily tailored to any other + supported device and development board. + +@par How to use it ? + +In order to make the program work, you must do the following : + - Copy all source files from this example folder to the template folder under + Project\STM32F10x_StdPeriph_Template + - Open your preferred toolchain and setup your project configuration as follows + - Add the required example files + - accesspermission.c +<ul> +- For RIDE and TrueSTUDIO toolchains you have to follow these instructions + + <li> RIDE + - In the Application options -> script menu, set "Use Default Script File" + to "No" and use "stm32f_flash_ROAarray.ld" as Script File. + This linker is configured for STM32F.
