Hi, I do not have a lot of experience with the STM32. I used other processors in the past like the LCP1768. We developed a custom bootloader to be able the load a new firmware into the uProcessor. In our current case, the STM32G474 is connected by ...
Hi Pascal, Any updates on our previous thread? When testing the same firmware with the EN pin pulled up, we are facing some issues during operation. After about 5–6 operation cycles, the system stops working until the MCU is reset. The issue still pe...
Hi team.I am using STM32U575RIT6 how set the internal and external clock configuration , i have bit confusion can u gide me to resolve this .thnaks.
Hello,I designed a custom PCB using the STM32H745IIT6 (LQFP176) and I cannot connect to the MCU using SWD with an ST-LINK V2. I always get “Error in final launch sequence / No device found on target”. Hardware summary: VDD, VDDA, VREF+ → 3.3V VCAP1...
Good day! I use TIM15 and DMA1, channel 5 in STM32H743. If DMA and data have a size of 32-bit, then everything works fine. If you configure DMA on 16-bit data, then 32-bit data is still written to the TIM5 registers. In order to save memory, I wan...
I've searched and not found anything describing this behaviour (on the internet or this forum, which I've found to be an incredible resource so far - thank you).I have a configuration where I go into STOP, exit out of STOP via EXTI, start TIM1, allow...
Hi, I am currently trying to make a single pulse test jig I can use to test MOSFETs in an series resonant converter. I am using the STM32F411CEU6. I am trying to make a state machine that can make these signals at two different pins. The two variabl...
Hi all,I have developed a bootloader for STM32F412, the bootloader works perfectly, however, when I change the user app to be FreeRTOS based, it ceases to work.I added a blink led in the Hard Fault in both the bootloader and app, but both were not tr...
Hi, I am using a NUCLEO-G474RE with the X-NUCLEO-SRC1M1 board. I have created and configures the project according to https://wiki.st.com/stm32mcu/wiki/STM32StepByStep:Getting_started_with_USB-Power_Delivery_Source I am monitoring the board with the ...
I have an STM32F103 board call 野火STM32F103ZE_霸道开发板，i found enable FSMC clock will pull up PB7 GPIO to 3.26v , i try decrease my code ceaselessly to verify this bug, finaly it can reproduce bug easily like this #include "stm32f10x.h" int main (v...
