HelloI am new with using STM MCU's (STM32G474RET6) and encounter very strange reset behavior.In my application reset of the MCU can be done in 3 different ways. 1. Hardware reset - by pressing on button.2. Software reset - by executing NVIC_SystemRes...
Hi,I'm trying to transmit some data using FD-CAN but HAL_FDCAN_Start() function returns error code 38. I have taken reference from STM32H743-EVAL kit example.I have configured same as mentioned there. But still i couldn't figure out the issue behind...
This is regarding a new project creation in STM32Cube IDE. I selected STM32U585CITx MCU. After project creation it showed me the following dialog box as shown in the screenshot attached.Please help how to proceed.Screenshot of FirmwareUpdater issue
We are using STM32H723 on a custom board.Right now, we are not measuring RTC calibration, we just have a possibility for the user to manually insert values of CALM and CALP elements in RTC_CALR register. We want to inform the user about resulting fre...
Hi,I'm using 2 STM32F4 MCUs for Modbus TCP Server/Client implementation based on LWIP. One MCU as a Client and other one as a Server. I have connect both MCUs through D-Link DES-1016D ethernet switch.The problem is when I connect both MCUs directly (...
I have written a bootloader that is used to update the application code via a Modbus interface over USB.I'm still working on the code to start the bootloader when new firmware is to be uploaded to the custom board. My board has a buck and an inverti...
Hello.I am trying to learn about DMA with spi. I tried HAL library which worked fine for me, I tried the LL Examples (stm32L4x) provided in repository which worked fine when i am reading once with loopback. Now i am trying to use a full duplex master...
Hello forum members, I am currently working on a custom PCB based on the STM32U575ZIT6 microcontroller. I've encountered an issue when configuring PLL1 as the clock source – the code generates a hard fault. However, when selecting HSI or HSE as the s...
Hello ST Community,I've been troubleshooting an issue with writing to address using system Bootloader on the STM32U5A9J-DK. According to AN3155 Application Note, the data to be written during the 'Write to Memory Command' should be a multiple of 4 by...
Hello,I want to make a design with the ADC1283 where DVCC is powered by a 5V buck converter, and AVCC is powered off a 4.5V voltage regulator (that's powered off the buck converter). Is this possible?I can't tell whether DVCC and AVCC are allowed to ...
