On a STM32F469, when jumping from DFU bootloader to main image, I have seen that the RCC_AHB1ENR register is set to 0x0 and not 0x0010 0000 which it should be after a reset, according to the documentation. This causes the CCM RAM to be disabled.Accor...
Processor: stm32h753vitoolchain: IAR Embedded Workbench 8.4The project is to port an existing bare-metal boot-loader and application to the stm32h753vi The current design consists of a boot-loader(64K - 1 sector) and application in flash (128k - 2 se...
Hello there!I'm having serious trouble to configure CubeMX and HAL to obtain a Virtual COM port in a STM32F107VC application.Recently, I sucessfully acomplished it with zero effort for another board using STM32L443, and I'm repeating the steps for F1...
Hello, I am working on Custom HID and I tried a week but no resultmy problem:I created Report Descriptor like follow /* USER CODE BEGIN 0 */ 0x06,0x00,0xFF, //Usage Page 0xff00 0x09, 0x01, //USAGE (Pointer) 0xA1,0x01, ...
This was provided in the STM32Cube Examples for STM32F767ZI-Nucleo. I do not understand why the pulse has been configured with different values for the different Channels. They are turned off and on as required by the commutation sequence, so I do no...
Hi!I'm using STM32h7hal library. Stm32 FDCAN doesn't have "automatic busOff recovery" flag. Therefore i have to use HAL for bus off recovery sequence.Is code below correct for recovery ?HAL_FDCAN_Stop(hfdcan);HAL_FDCAN_DeInit(hfdcan);HAL_FDCAN_Init(h...
We developed a product which uses STM32F series and everything works fine. For some reason, we need to swap the F serie to G serie for future products. Unfortunately, we do not manage to flash the virgin device (STM32G070CBT6) through USART1 (PA9/PA1...
Hi. I have stm32f722re connected with emmc MTFC4GMWDQ by 8-bit interface. When I read out the data from the card, I see in the debugger that starting from index 512 to the end, the second buffer is filled with zeros.This behavior is observed in block...
Hi ST Community:I'm appling STM32H743 with eMMC card in my project. I call function "HAL_MMC_WriteBlocks" for block writing. The problem is when I write one block every time, the write operation is ok. When write more than one blocks, it get failed. ...
Hi,I have downloaded and installed the STM32CubeIDE and have used it to do a blinky LED on a NUCLEO-L476RG, so basically have a bit of an understanding of the IDE and coding/compiling & burning.However, I'm lost as to how to proceed in getting my P-L...
