Resolved! STM32F415 DMA SPI transfer after stop mode
I am using SPI2 and SPI3 with DMA1 to write and read to/from peripheral chips. This works fine most of the time. At the same time I am using the stop mode to save power. Now in some cases just after leaving the stop mode, the next DMA transfer does n...
HAL_FLASHEx_Erase and HAL_FLASH_Program both return HAL_ERROR but erase and write are done.
These problems are probably related. I'm running STM32G473 at 160 MHz. I'm attempting to erase one page followed by 34 double-word writes to the same page. The code and the target are both in bank 1, but the problem occurs if I move the target to ...
Resolved! STM32U575 SMPS time out when enabling. What to check for?
My controller uses the STM32U575 chip. I followed the recommended design for the SMPS using the same inductor and XR7 capacitors as recommended in the reference design. I built up 4 boards, the first three boards worked properly without issue. After ...
fail to write on sd card on stm32 g491re
Hi all,i am currently writing a program which is supposed to write data on an sd-card. This has worked until i changed my laptop (and cubeIDE version from 1.13 to 1.17) and until i added line 127 "HAL_GPIO_WritePin(GPIOB, GPIO_PIN_0, GPIO_PIN_SET);"....
Using Hex file or Bin file for FOTA?
Hi community!I've been tasked with designing and programming a new product that includes a bootloader and LTE communication, the main issue I'm facing now is to design the whole updating and downloading process, supposedly I'll store the update in a ...
Resolved! stm32f4xx hal systick question
in stm32f4xx_hal.c file the function __weak HAL_StatusTypeDef HAL_InitTick uses a function HAL_SYSTICK_Config thats in stm32f4xx_hal_cortex.c file and that function uses SysTick_Config(TicksNumb) but i cant find this function .just wondering where th...
Failed to inerface (4 and 8 GB) pendrive to STM32H747
Dear Community, I am currently working on interfacing of USB (pen-drive) in FS mode with STM32H747BIT6.I have observed that during the enumeration process of pen-drive it is failing to proceed at the functionUSBH_HandleControl --> case CTRL_SETUP_...
Practical implementation of NAND using FMC in STM32H723
Hi,I am implementing an application that uses FMC with a Micron NAND 8bit 16Gb Asynchronous MT29F16G08ABACA. My questions are more theoretical:1. Is it convenient to access this memory using FMC? I have read somewhere in this forum that also eMMC (SD...
LPTIM behaviour
Hallo, I'd like to use LPTIM to count the number of digital impulse of a signal.So, the signal is connected to (in this case) LPTIM2_IN1.The init function (MX_LPTIM2_Init) is as this: hlptim2.Instance = LPTIM2; hlptim2.Init.Clock.Source = LPTIM_CLOCK...
