The STM32CubeG4 package comes with CMSIS v5.6 (https://github.com/STMicroelectronics/STM32CubeG4/tree/master/Drivers/CMSIS) which I think was released in July 2019.Is it necessary to use this version or can I upgrade it to a later release? Currently ...
I am having touble re-entering standby after a RTC wakup. I am using the STM32L412 (Nucleo-32)I have written some code that enables and sets the RTC, then sets alarm A and alarm B, before going into standby. After the correct time has elapsed, alar...
Hello, when I was using the STM32H563 I3C, I found that when configured with VDDIO2 = 1.2V and a frequency of 12.5MHz, the data read in SDR mode would be misaligned. The waveform received on the SDA line was 0xF9, but the MCU received 0x7C. After I i...
Hello,I'am currently programming on a STM32G473. I'am sending CAN Message via the FDCAN peripheral.In generally everything works, all my messages I put into the Tx Buffer are sent.But in one little detail I'am confused:In Figure 669 its described, th...
Hi,I'm encountering an issue with my STM32H750 MCU. I download my program to the flash via the UART interface using STM32CubeProgrammer. The MCU can work well for a few days, but suddenly crashed. This problem occurred randomly on 2 out of 15 boards ...
In some readings, I saw that there are some STM32s that can be used to control Switched Mode Power Supplies. Are there any suggestions for articles with more details on the subject?I am writing a book about "SMPS" and would like to dedicate a section...
Hello,I've designed my own PCB using the STM32H533CET6 microcontroller. However, when I try to connect to it using an ST-Link V2 via SWD, STM32Cube Programmer gives me the error: "Cannot identify the device".I've already tried connecting under reset ...
I'm using a STM32L151RBT6 and trying to debug with a STLink V3.The debugger loses connection when I encounter the line:PWR_VoltageScalingConfig(PWR_VoltageScaling_Range3); Specifically, when it changes the PWR-CR Bits 12:11 (VOS). I have no issue cha...
Hello, I've just received my custom PCB with an STM32H743VIT6 MCU. It has a Samsung eMMC connected to the SDMMC1 interface (MMC 8 Bits Wide Bus) : (I'll link the eMMC datasheet below.) I'm encountering some issues while initializing the device with ...
Hi ST team, Today I have an issue in my hardware.I flash a software via STLink in debug mode succesfully. When I start the program, the console shows that "cannot read register..." or something like that :( I cannot remember.After that, STLink cannot...
