Hi everyone,I'm new to embedded programming and trying to understand how SVC (Supervisor Call) works on ARM Cortex-M.I wrote a small program that triggers an SVC call, and in the SVC handler, I try to extract the SVC number by accessing the PC that w...
We are experiencing issues when using system bootloader on STM32H7 MCUs. Enter to the bootloader is correct - when BOOT0 pin is held high and reset is performed, MCU enters system bootloader. We use USB DFU for communication with bootloader and PC ca...
Hello all.Personal emotional outburst (just jump it if you don't work for stm):I can't understand how it's possibile, but every single time I trust STM and go for an update, everything stops working and I have to loose hours of my life trying to fix ...
Hi, My board consists of stm32h733 that interfaces SDRAM via FMC. I want to execute code from SDRAM. Code is loaded from external flash(OCTOSPI) to SDRAM at address 0xc0700000.But running the code from this region causes hard-fault disabling the Debu...
I'm using the internal temp sensor on a C011 chip *actually the STM32C0116 dev board) and trying to get an approximate reading in C, using __LL_ADC_CALC_TEMPERATURE_TYP_PARAMS macro.I understand that this won't be very accurate, but it seems that wh...
Hello :)I'm trying to get the mentioned display expansion board working with my NULCEO board. I already downloaded the X-DISPLAY examples and found a configured ioc file for an H723 so I replicated all the settings to match my H745 one.Unfortunately ...
I am using the STM32H743VIT and trying to integrate using LTDC. The Display Type options in CUBEMX only allow 16 or 18 bit RGB. I know there is no LTDC_R0, so I assume that is why there is not option for 24 bit RGB; however, we were just planning on ...
We’re working on a custom board based on the STM32U5 series. We've already developed the low-level drivers, and now we’re moving on to the firmware application layer. We’re currently evaluating RTOS options and considering FreeRTOS and Zephyr.Some qu...
Hello community, In my project requires upto 16384 points of FFT(Fast Fourier Transform) . I found out that I can’t perform this number of FFT points using arm CMSIS DSP library since it is limited to 4096 point Max. Due to this I have to use externa...
Hello ST Community,I am currently working on programming an STM32G070RBT6 via UART using an FTDI interface connected to my PC via USB. Initially, the STM32 CUBE programmer successfully uploads the program once, but subsequent attempts to upload fail....
