HAL_RCCEx_GetPLL3ClockFreq() computes the frequency of the three outputs of PLL3. When PLL3 is in Fractional N mode it reports wildly inaccurate frequencies which can affect the setup of other peripherals like the SAI.The problem is that the PLL3 cod...
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. ...
