I am faced with an interesting problem. The code I have seems to run only after I press the reset button. If I somehow remove power, and put it back, it will not run until the reset button is pressed. HAS ANYONE ever had this problem ?All my power r...
The two buttons next to the STM32H735 I bought fell off during the shipping process. Will this have a great impact on the use?
When I program to my stm32 MCU, I need to hard reset to lower the current consumption. I mean, after I programmed the MCU, the board consume 580uA. Then I do a software reset via NRST and still had the same current consumption. Then I do a hard reset...
We have seen PVD triggers when there is transient load of 1A added on the 3.3Vdc (loaded additional to our design through electronic load) and it triggers when the transient load dips the 3.3V for duration of ~450 micro seconds.We have seen BOR trigg...
Hello,It's not clear for me what a peripheral reset (registers RCC_xxxRSTR) is doing. I didn't find the details in the reference manual. I assume it resets the internal state machine of the periph, its FIFOs, but for example does it also reset its co...
Hi everyone,I am currently migrating from STM32F303x to STM32G431x microcontroller (48-pin package) and started testing the GPIOs in reset state, without any firmware on-board. Also, there are no external HW circuitries connected to the pins (I meant...
The notes in the STM32F76xxx data sheet DS11532 Rev 7 give 2 different answers to this question. See attached. I'm guessing the default state of the unconfigured GPIO is "Floating Input."
I have been battling an issue for a while where upon a watchdog (WWDG1) timeout, the system was not correctly reset. I was finding that the CPU and NVIC are reset but all the peripherals are not reset after a watchdog reset, they keep their exact reg...
In my design, I have two MCUs, the STM32F103RCT6 and an ESP32. At some point, the ESP32 will perform a firmware update of the STM32. So it will need to reset it through the NRST pin, controlled through a GPIO. I have checked rapidly the datasheet, th...
When flashing a bin file to a blank/erased STM32G070 the --reset option does not consistently reset the processor after flash. The first couple times I did this it worked. Now it is not.A snippet of the output from a failed example using the command ...
