STM32H7 bank swap break at address 0x81006fe

with the ST32 H743ZI2. I wasted much of time to fix it but i didnt get it. Maybe because im new in STM32 controllers. I copied the bank swap code from STM32CubeH7 Firmware Examples and did a few modifications regarding to gpio configuration in CubeMX. I did them because i want to implicate the code in a excisting project without the stm32h7xx_nucleo headers. Following the Code for Bank1: [c] HAL_FLASH_Unlock(); HAL_FLASH_OB_Unlock(); while (1) { /* Wait for BUTTON_USER is released */ if (HAL_GPIO_ReadPin(GPIOC

CMSIS-RTX with GCC on STM32F4 Discovery

searching, this maybe the first project that provides a reference for CMSIS-RTX with GCC working on an STM32 device. Cheers!

Hello Rajiv Verma, I appreciate your hard work. Great. When I tried it in my STM32F407G-DISC1 board, I found that the tempo was little bit slow. Apart from that, all are okay. Cheers

yagarto example project for STM32F100C4 chip

Hello, I'm new user of the yagarto tool-chain. The example project for STM32F103 works well for me. I'm going to move to simpler target chip STM32F100C4. It should be the Low density Value Line device (STM32F10X_LD_VL). I'm not sure how to setup-up project or how to modify linker script and start-up code for that chip. Please can someone send me a example project for STM32F100C4 for yagarto or any advice how to do it please?

Circuit for STM32F401RDTx [ARM]

Hello, I am trying to design a circuit for the STM32F401RDTx. I proceed as per the datasheet, Application Note 4488 from ST, and Carmen Noviellos "Mastering STM32" , but I don't find it simple at all right now and have a few questions. I have attached

and all other supplies via a switch (per hardware or per software+fet or so). Usually all the STM32Fxxx have a built-in boot loader, so it's the best, to have on your maintenance connector some more signals: gnd, vcc, /reset, boot1 or boot0 (depends on the part. chip, so read the manual), txd1, rxd1

Interrupt handler in C++ File?!

Hi guy's I have the following problem. I'm using the STM32F103RB and Sourcery G++ Lite 2008q1-126 and I try to implement the Interrupt Handlers in a C++ File. I'm using C and C++ Code in my project and if I implement the handlers in a C File everything

You cannot do that as part of a class. I don't know the STM32, but my guess is that interrupt vectors are known by their global name, so they cannot be established using C++ name mangling. This also implies they cannot be hidden with in a class (class members

STM32 GCC problem writing to flash bank 2

I am developing a project running on an STM32 target, using Eclipse, openOCD and CodeSourceryLite 2009q1-161. Part of the design is that the user should be able to upgrade the code in flash, so I partition it into a bootloader and two equal sectors

the code in the second sector. I was able to debug this code (using optimization level 0) on an STM32F103xD (which has 384K of flash) when unoptimized code was about 160K. However, the code has now grown to 220K unoptimized, 130K at optimization level 's'. Therefore I have been able to finish debugging

Atomic write - STM32

Hi, I'm currently working with a STM32F4 and try to implement atomic access to variables (e.g. mutexes). Currently, I disable all interrupts before accessing a mutex, and enable them afterwards. Now there exist the LDREX and STREX commands on the STM32, which seem to be perfect for my application. But how do I use them correctly? In the manual it says that an STREX *must* have the same address as the previous LDREX. So I still need to disable interrupts
