STM32H7 WWDG1 on Cortex M7 - Early Wakeup Interrupt Context Backup

Hi,I am looking on getting CM7 CPU Context backup inside Window Watchdog Early Interrupt handler (HAL_WWDG_EarlyWakeupCallback). The CPU context should include LR, PC, PSR, R0 to R3 and R12.Any help, example or code reference is appreciated.Thanks

Is it possible to use STM32H750VB with two QSPI Nor Flash in Memory Mapped & Read/Write Mode

Hi, i want to use STM32H750 with two QSPI Nor flash (W25Q128JV). Purpose of one of them is store static libs and constants. So i will use in memory mapped xip mode. The other one is using in read/write mode for store data.Before, i have used both of ...

Setting clock to 168MHz on the STM32F407 and enabling MCO1 [bare metal]

Hi,I'm trying my hand at bare metal programming on the F4 Discovery board. I've been loosely following this code to get the RCC configuration sequence right to set the main sys clock to 168MHz but with my adaptations. I'm able to see 16MHz on MCO1 (P...

Please help solve the problem STM32H743IIT6

I'm using an stm32f429 2MB dual bank mcu and erasing a sector in flash bank2 from code running in bank1. I can't achieve this without the code in bank1 stalling. I can't find any documentation relating to the stm32f429 2MB to allow this.

For the  stm32f429 1MB dual bank there is documentation relating to setting dual bank mode, and for the  stm32lxxx there is documentation relating to setting dual bank mode, but not for the stm32f429 2MB dual bank. I'm wondering now if read-while-wri...

STM32CubeF7 QSPI Flash example issue on STM32F769I_EVAL

Hello,I'm currently playing around with the QSPI_ReadWrite_DMA example on an STM32F769I_EVAL board.Link to example: https://github.com/STMicroelectronics/STM32CubeF7/tree/master/Projects/STM32F769I_EVAL/Examples/QSPI/QSPI_ReadWrite_DMA.The demo seems...

Is it recommendation to used internal RCC clock instead of external crystal.

For peripherals like SPI as HCI, I2S which clock should use RCC or external crystal?

Hi every one, I am using STM32F469 discovery , I just created a project in touchgfx with 2 png background screens and and when I refresh and compile this project in IDE I got errors .

the errors like :\st\stm32cubeide_1.6.1\stm32cubeide\plugins\com.st.stm32cube.ide.mcu.externaltools.gnu-tools-for-stm32.9-2020-q2-update.win32_1.5.0.202011040924\tools\arm-none-eabi\bin\ld.exe: STM32F469I-DISCO.elf section `ExtFlashSection' will not...
