Hi all!uC: STM32L433VCTCubeMX, CubeIDE, CubeProgrammerI've configured my RTC to set an alarm every minute. When an alarm occurs, the next alarm gets set and so on.About once to twice a day, the rtc alarm is skipped, so there's a continous error, beca...
I'm running the board on 3.3v, and as per documentation: +3V3 power supply Using the +3V3 (CN4 pin 14) directly as power input, can be interesting, for instance, in case the 3.3 V is provided by a shield board. In this case the ST-LINK is not powered...
Hello Experts, I designed my custom board with reference to AN5419 application note (Getting started with STM32H723/733, STM32H725/735 and STM32H730 Value Line hardware development). but it doesn't work.When i apply to power to the board and connect ...
Had a look at the newest 'F437/439 datasheet (wonder why 'F427/'F429 was not updated with the same things, e.g. ETH_MII_RXD2 missing in the AF table for PH6):I don't think it was supposed to look like this.JW
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:
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...
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...
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...
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...
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...
