Hi,I'm writing a bootloader, the application binary is read from a SD card connected via SDIO and will be written into the SECTOR 2 of the micro controller (starts at 0x8008000 == APP_ADDRESS), the bootloader is stored in SECTOR 0 and SECTOR 1, start...
So somehow through my chain of execution I end up herevoid _exit (int status){ _kill(status, -1); while (1) {} /* Make sure we hang here */}From disassembly it seems that the functions preceeding it areITM_SendChar()and before thatHAL_CAN_Rx...
Hi,We are using STM32F479 processor in our design. Now we are in process of optimizing our code, How can I determine the maximum Stack and Heap used in the Project. We are using Keil Compiler and application is based on RTX OS. For thread level optim...
Hello,We have a custom System-On-Module based on the STM32F750N8H6 MCU. We successfully installed 50KB-size U-Boot SPL and 220KB main U-Boot images into the internal Flash, and they work.Could please someone explain how is that possible? Device datas...
Hi,I have experience of 16bit microchip micros using embedded C, and i am about to move across to ARM RTOS C++. I have narrowed my chip vendor down to ST. As i am starting from zero on ARM development, could you offer advice on which is the easiest d...
Dear ALLI got an problem when i use STM32F429 standby mode.In the first time enter the standby mode it woks fine. I use PA0-WAUP pin to exit the standby mode. But, i make another try to enter the standby mode, it immediate reset。It is seems it entere...
I just received my new boards with STM32F730R8.I have always done UART flashing (*.hex file) that worked great on all other devices (STM32F1xx).But it does not work with STM32F730R8.Here I do not have the abilty to flash with JTAG.The latest FLASH LO...
Hi,As for the STM32L486, it have 3 ADCs. Is There only 1 ADC common registers ADCx_CCR (x=1,2,3) for all or individual for each ADCx?In IAR IDR Arm8.32.2, the SFR setup information states that it is only one ADC_ CCR for both 3 (atached picture). Thu...
The question is regarding Nucleo-l476RG, I need to use 5 ADC, 12Bit. No matter what I do. I cannot see that these pins are connected to anything else. Why do I get a wrong reading on these GPIO? Please notice that my board is new .. the MCU is not da...
I need to implement the reset button functionality without pressing the reset button by using, maybe, a GPIO pin on the STM board by giving HIGH or LOW on a specific pin using a GPIO of the Raspberry Pi. How can I do that?
