We have been building boards for years using the STM32F407ZET6. Our system uses a USART bootloader from a host processor running Android that uses stm32ld to do the bootloading. It has worked pretty much flawlessly for years. Recently we started rece...
Posted on November 17, 2017 at 20:27I have already read several posts about the subject. including 'DFU: LEAVE does not jump to application'.and 'Reset after firmware upgrade'Context : STM32F072RBusing either DfuSeCommand.exe or DfuSeDemoUsing the D...
I have a project that inadvertently appears to have what looks like the bootloader area.I'm using STM32CubeIDE and when I program the board from the IDE, it runs fine and all is ok. If I press the reset button then the board ceases to run.I've duplic...
When an empty STM32G041 (others may have the same problem, couldn'T test) is flashed with an application, an real power-cylce is needed to actually start the application. Until this power-cycle, ever reset (HW or SW) will jump to the bootloader.After...
Hello,I have a STM32L0x2 (M0+ core) project where, so far, I used to jump from the MCU app to my custom bootloader for updating the app in flash with a new program binary image, by setting flags in the backup registers and doing a SysReset.Now, that ...
Hello, I have a problem that I don't know to solve and any help will be appreciated very much. I'm working with STM32L476RCT, and BOOT0 is configured to 0 to boot from flash. The NRST state is also correct. My problem is when I program the mcu, the c...
I am using NUCLEO STM32L4R5ZI. I tried to access the boot mode using the following command HAL_FLASH_Unlock(); while(FLASH->SR & FLASH_SR_BSY) ; HAL_FLASH_OB_Unlock(); while(FLASH->SR & FLASH_SR_BSY) ; FLASH->OPTR &= ~(FLASH_OPTR_n...
The MX_RTC_Init function resets the SSR register of the RTC, so with every power cycle there is a average error of 0.5s! That can accumulate to quite a huge error pretty quickly, if the device is switched on and off several times a day.Is this intend...
I'm using STSPIN32F0A witch is based on STM32F031C6 MCU and in my case BOOT0 pin is always connected to the VDD to force the board to boot on system memory, and the idea is to jump from the bootloader to the application on the main flash using the bo...
Hi,I'm trying to reset one STM32 MCU using another STM32 MCU via NRST Pin. I'm pulling down that NRST Pin using GPIO Output Pin of Host MCU. In this case what should be the GPIO configuration (Push-Pull/Open Drain)(No Pull Up Pull Down/Pull Up). Same...
