Hello,we are using a STM32F429.The bootloader is located in the first 64kB. The firmware in the remaining sectors.It erases the remaining sectors of the flash and writes the new firmware.Now, 3.6.5 Read-while-write (RWW) of the reference manual state...
I have a stm32g031k8 board. I was trying to give a pwm input signal like a square wave, measuring the frequency and duty cycle and generate pwm signal of that frequency and duty cycle using another timer. I was also changing the frequency and duty cy...
Hi.I was searching for a crystal that meets the requiremets for the HSE of the MCU I´m using (STM32L4P5RGT6) at the beginning I tried to make the corresponding calcuations by myself but after researching I noticed that for some calculation I needed m...
Hello,i'm trying to implement firmware upgrade in my Windows application via USART for stm32f103 following AN3155. My issue is with the Write Command. More specifically:- if i send 1 byte of user data at time it works, it's just slow cause i have to ...
We're using a STM32H747IGT6 and using hardware semaphores to coordinate between the two cores.On the CM4 I've set up TIMER3 to run at full blast: LL_APB1_GRP1_EnableClock(LL_APB1_GRP1_PERIPH_TIM3); LL_TIM_SetPrescaler(TIM3, 0); // Count at sy...
I have a custom board with an STM32U083KCU6 MCU - see schematics belowVBAT = +3.6VI have 2 boards:1. board: I flashed it via SWD but forgot to enable it in STM32CubeMX, which means that I'm not able to flash it again via SWD2. Board: This time, I rem...
Application note AN5361 "Setting up with ST-LINK GDB server" says "Set the Cortex®-M7 core running so that the HSEM semaphore is released and Cortex®-M4 wakes up from Stop mode" and this post implies that it's "HSEM 0" which I'm assuming is HSEM chan...
I am working on a H755zi-Q Nucleo board , I am using the flash memory to store some parameters and i have implemented flash wearing as well, All this works fine , my data persists across resets and is correctly loaded upon reset, and i have even veri...
Hello everyone,I am currently working on a project using the STM32H755 microcontroller, and I am facing an issue with the program getting stuck in the `Reset_Handler` during debugging. Specifically, the code halts at the instruction `ldr sp, =_estack...
We try generate signal defined by toggle table , but command do nothink. (except ARR toggles) if (HAL_TIM_OC_Start_DMA(&htim2, TIM_CHANNEL_4, &tim_values[0], idx) != HAL_OK) { Error_Handler(); }have 1.7.0 U5 firmware some known issue ? O...
