How to achieve the lowest power consumption while running in RAM?
I want to execute a program by copying it from flash to RAM on power-up. How can I achieve this?STM32CubeMX's PCC tool as shown in the diagram:

What is the best way to re-enable SysTick after resuming from sleep, specifically for interrupts?
If you put an MCU in sleep mode with WFI, such as the STM32L452, you are supposed to suspend the SysTick and resume it after. Usually this is done in the main thread context. However, when you have an interrupt, I believe the next instruction will be...
Resolved! ADC making code not upload correctly
Hi, I'm programming an STM32F030C8T6 MCU. When I attempt to upload my code, it gives me an error: "Could not halt device (19)". I noticed that this only happens when ADC is enabled from CubeMX. When I disable it, everything works fine. The code doesn...
STM32L073RZT6 UART Stops responding after power-on, reset fixes issue
Hello,I am working with a custom board communicating via USB-2-USART IC (FT234XD-R). Upon power up, the board operates as expected. I can communicate with the device . After some time--usually 60sec or so, but not perfectly periodic-- the device will...
STM32H723 BOOT0 and RESET control over UART!
Hi All, I managed to be able to bootload the STM32H723 device using the STM32 Flash Loader (STBootLib) but do not like how I have to pull BOOT0 high and also reset the device right before I program the device and then when the boatloading is done res...
Resolved! Launching the application from CubeIde vs autonomously
Hello,I wonder if someone has knowledge about any difference in how variables are initialized and handled when launching an application from CubeIde vs starting up the MCU.My case: I use a STM32H7 and the application runs regularly when I launch it f...
Resolved! STM32F103 CAN filter range of ID's
Hello, I have a set of extended CAN ID's I need to pas the bxCAN filter. I looked at some examples where one ID is passed the filter, but could not figure out how to allow a set of ID's. If my understanding is correct the mask is used to determine wh...
Handling ECCD error during flash read on stm32l4
Posted on October 09, 2016 at 20:03Hello,I'm building an application with ST STM32L4 that stores information on internal flash (ECC flash on L4). The information is valuable, so the flash programming must be robust to unexpected shut downs including...
Resolved! Short question regarding the contact drillings
Good Morning Ladies and Gentlemen, Could you communicate in a short way the size of the contact drill-holes (stm32f411 - CEU) ?The diameter in AWG size would be enough.We also are interested in further documentation-links regarding it. In student wor...
STM32L412 Standby+RTC battery current use
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...
