The reference manual documentation for the onboard temperature sensor for STM32H745, RM0399, chapter 26.4.33 gives a formula for calculating temperature that is only valid when VREF is 3.3 volts, but lacks mention, foot note, etc of any kind that VRE...

I am releasing my first product using a dual core STM32H745. Our board manufacturer is using Segger J-Flash to load our application hex files. The process for flashing our released firmware is to load a Segger project setup for the M4 core and our ...

I have a product using a STM32H745ZIT that has an input signal connected to TIM1 ETR and in the normal case, an edge on the ETR using slave mode trigger results in a one pulse pwm output a set time later driven on TIM1 CH1 and TIM1 CH2. A new use ca...

I'm bringing up a new project using STM32F733, with code generated from CubeMX version 6.6.1, with difficulty. Looking for suggestions.1) When I change the HAL timebase source from the default SysTick to something else, I've tried TIM2 and TIM10, the...

I'm using CubeMX 6.3.0 with a STM32H755 micro. The cube mx generated code assumes a HAL_PWREx_ConfigSupply( ) setting that is not correct for my hardware. Is there a place to configure this setting? I notice PWR is setup under Power and Thermal bu...

@SofLit Yes, srec_cat.exe is working fine. In IAR under options -> build actions -> Post-build command line I call a bat file like the following:$WS_DIR$\package_hex.bat $WS_DIR$Note that $WS_DIR$ is an IAR keyword for the path of the workspace whic...

Thanks @Tesla DeLorean, combined seems to be working fine. The Segger software forces you to pick the target core, and the M7 selection has the M4 flash range disabled by default. But after you go into options -> project settings -> flash, pick bot...

Thanks for the reply, were going to update our design with an external MUX to choose where the signal goes.

Thank you Pavel and Tesla, your answers sent me down the right path.The function SystemInit() which is called before main by startup code and contained in system_stm32f7xx.c was indeed not setting up the vector table correctly. The project that cube...
