why does this work:HAL_UART_Transmit_DMA(&huart6, (uint8_t *)"stm32\n", 6); // works and sends dataand this doesnt:ALIGN_32BYTES (uint8_t aTxBuffer[]) = "stm32\n";HAL_UART_Transmit_DMA(&huart6, (uint8_t *)aTxBuffer, 6) // doesnt send any datawhat am ...
I am searching for an expert. We are having problems with the RTC jumping all over the place. Has anyone here 1) experienced this, or 2) Could point me in the direction of where I could find someone? My company depends on it. Thx!

I try to set up an USB CDC project for a STM32L412KB Nucleo32 board using CubeIDE.I activated the USB connection and the USB middleware with the default USB CDC setup.If I run this code, it ends in the hardfault handler with INVSTATE raised during th...
Hi,I have created my own board on STM32F405RGT6 and I want to use MicroSD card with it.My problem is that the file system mount is working but not the file open. While f_open() is invoked the board freezes for about 30 seconds and later returns "FR_D...
Hello, ST expertsAR8031 Ethernet PHY works on STM32F417 custom board. MII interface is used here. When PHY works on normal mode at 10Mbps, everything looks fine. But when link speed is set to 100Mbps, the ethernet part can not work, HAL_ETH_GetRece...
Hi,I have a custom board based on STM32H750VB that has Ethernet connection. I want to develop a bootloader code that can program Flash for system upgrade purposes. I read in the datasheet that there is a bootloader in System Memory and is programmed ...
Creating a new example project for the Nucleo Stm32h743 board, it enables the ethernet (RMII ) and a LED PB0, yet the Configuration Tool Gui shows a yellow conflict triangle between the RMII and LED.I haven't tested the ethernet, but presumably the e...
Using custom board with l462re, sdcard connected directly to mcu without external pullups.SDMMC clockdiv set to 10, SDMMC freq set to 48MHz.When ever I'm trying to use f_write or f_mkfs they return FR_DISK_ERR.Sometimes sdcard is corrupts(file is cre...
I have not been able to get the device to enter USB DFU boot mode (hold boot PIN and reset). I've used many other ST devices and have never had an issue with this. I'm sure it's something simple. What are the dependencices for USB DFU boot to star...
