The first instruction of your program is stored at the address 0x0800 0000. Flash start at the address 0x0800 0000 and finish to the address 0x0807 FFFF. Note that address of the flash is contiguous (linear address) but is divided in 8 sector. Reference Manual is very important for know in deep the Peripherals, the Boot Mode Configuration pins, the Embedded bootloader and the Memory Mapping of your STM32.īelow there is the 512KFlash memory map of the STM32F401RE. Normally the Data Sheets ( DS) cover a lot of similar MCU, for know which peripherals, how many I/O, Flash, etc, you has in your particular mcu open the DS and go to the page named DESCRIPTION and look the column on the vertical of the name of your mcu and package, see the below example, yellow boxes. On the board there is the STM32F401RE (LQFP64), it’s important remember that for any STM32 there is 3 fundamental manuals that are: In our case the manual is: UM1725 – Description of for STM32F4 HAL and LL driverĪs we mentioned above, for this first example we use the NUCLEO-F401RE but you must use any STM32 eval board. The concepts present in this page are the same for any STM32 families.įor know the functions that are available for drive the MCU is necessary download the User Manual that describe the HAL and LL functions, this is a big manual and is in the Resources -> User Manuals section, see below.: In any case, feel free, to choose the STM32 evaluation boards that you prefer. In our case we decide to use the STM32F401REand the NUCLEO-F401RE and so we download the F4 library. Low Layer ( LL) APIs, a light-weight, optimized, expert oriented set of APIs designed for both performance and runtime efficiencyīoth the HAL and LL APIs are production-ready and have been developed in compliance with MISRA-C®:2004 guidelines with some documented exceptions (reports available on demand) and ISO/TS 16949.įurthermore, ST-specific validation processes add a deeper-level qualification. The Hardware Abstraction Layer ( HAL) enabling portability between different STM32 devices via standardized API calls Middleware components (USB, TCP/IP, Graphics, FAT file system, etc) It’s also necessary download the STM library package for the STM32 families that you decide to use. See here for know how to install STM32CubeIDE. The official documentation regarding STM32CubeIDE is: UM2609 – STM32CubeIDE user guide Power the NUCLEO using an external USB power supplyįor create a new project for STM32 first install the STM32CubeIDE and also you need to have an STM32 eval board, we suggest to use a NUCLEO 64pins boards that are not expensive and is possible buy it on Internet.Take care also about the HW project for make a good product.What happens to the power on of the STM32 ?.Example techniques for detecting stack overflow, priority inversion and other common RTOS issues.Methods for enabling system trace (RTT, TCP/IP, USB).Understanding Data Watchpoint and Trace (DWT).Setting up an event recorder and monitoring system events.Performing a worst-case stack analysis during run-time.The webinar will provide hands-on demonstrations using the NXP's K64 Freedom Board which uses as ARM Cortex-M4 processor with the Keil MDK toolchain, RTX5 RTOS and Percepio’s Tracealyzer. Important concepts such as properly sizing thread stacks, using event viewers and discovering issues such as priority inversions, deadlock and thread starvation will be examined. In this webinar, attendees will become familiar with the latest and greatest techniques and tools necessary to debug their code. The problem is that many developers are just starting to use an RTOS and are not familiar with the methodologies and techniques necessary to quickly and efficiently debug their RTOS based application code. Using an RTOS has almost become a necessity when developing a real-time embedded system.
