I want to migrate from STM32F030 to STM32G071. Please tell me if errata section 2.25 (Overwriting with all zeros a Flash memory location previously programmed with all ones fails) could affect my custom bootloader or flash save functions from main...
Goodmorning everyoneA few weeks ago I started working with this board (NUCLEO-H743ZI2) and STM32CubeIDE, for the moment I have only faced simple problems such as timer configuration, interrupt generation and ADC readings.Now I need to program the boa...
Hello,I am trying to write to flash memory from the firmware itselfIt looks like the Erase process hangs for 2 seconds or so but works, but the writing process seems to totally freeze the MCU. Below is the code I am using. Any idea ?FLASH_EraseInitTy...
Want to use some function from the module like sending GPS location on analog request.
I am trying to build a current fed push pull DC DC converter. This requires two waveforms with duty cycle greater than 50% and phase difference of 180 dergrees. I would like to know the possible ways of achieving this. I have tried using output toggl...
I am using the STM32H745 dual core MCU, and the CM7 can be run correctly, but the CM4 go to the Hard fault immediately, I set a breakpoint at the start of main() but can't capture it. Then I set a breakpoint at Reset_Handler in the startup file (st...
Hi, I have a Nucleo F439ZI board and I am running a custom bootloader and application on it. My Clock config =In Bootloader I am using HSE external crystal (ST-link MCO 8MHz) for all peripheral clock which includes 48MHz clock for USB OTG FS in DFU m...
Hey,im going to use the H743 MCU in ~400MHz core frequency with Free Artos operation system.one of my uses is to sample an analog signal with external ADC in SPI Channel.An interrupt to the MCU will inform “samplenow!�?.im trying to figure how much t...
Im using external interrupts on an STM32L412. I want the interrupt to run as fast as possible so I'm not using the HAL to turn off the request, rather I am writing directly to EXTI -> PR1, which needs to be written high to turn off the interrupt, but...
