Hello all,I wish to setup the MPU early in my firmware, then prevent changes to the MPU registers until next power-cycle/reboot.Is this possible without having the root secure services? The MCU im using is the STM32H7A3. Thanks in advance.
Greetings,I'm attempting to make use of the tamper backup registers.I am enabling the RTC and have using LSI as the clock source.ROP is not enabled, I am not using the TAMP input pins, and i am debugging via SWD.As it is at the moment, writing a valu...
Hi all, The STM32L412xx and RM0394 are quite clear about current use of the micro when in standby mode with LSI-RTC.One thing the docs are not so clear about is the effect of having combined VBATT and VDD pins on the low pin-count packages. With thes...
Hi all,I would like to blend a ARGB8888 image onto my RGB565 frame buffer. Is this possible?The code I'm currently testing (that does not work) is the following:  //configure DMA2D options LL_DMA2D_SetMode(DMA2D, LL_DMA2D_MODE_M2M_BLEND); LL_DMA2D_...
This is a super super weird one.My device (STM32F401RC) uses the latest HAL libs vs STM32CubeIDE. USB is configured as device-only, CDC.It works *perfectly* until i also enable one of the I2C peripherals (HAL, config'ed as I2C slave) and send/recv I2...
