Dear all, I just came across something strange. I debugged into the function HAL_InitTick() to better understand how the OS tick (SysTick) is managed if FreeRTOS is used. I'm using TIM16 for the SysTick of the OS. At the beginning of HAL_InitTick() t...
We are migrating a project from H750 to H733 and I have run into an issue with our custom bootloader.We have our own External Loader, Bootloader and Application. Works fine on 750, but I have had to remake the projects for a move to the H733 micro.W...
Hi, I am trying to make the MCU the host where a USB can be connected, and the MCU can read/write to the USB. I configured my IOC /CubeMX to use the USB with FATFS. The USB USE OS (RTOS) is automatically enabled.However, the issue is that once the US...
I have spent over a week trying to get USB to work with my board, and have had no luck. As soon as the device detects the USB, the usb goes straight into a HOST_USER_UNRECOVERED_ERROR. I have received almost no assistance from STM32 regarding this, e...
Hello,I'm experiencing strange intermittent failures using STM32U575ZIQ using SPI and related DMA. MCU SPI setup: slave Rx-only mode, with slave select HW signal.SPI from the master (AD7768 ADC) shows 4MHz clock active all the time (even when there i...
Hi,I have an STM32F7 design with SD card connected via SDIO interface.In many posts I read that SD cards have to be initialized with a 1 bit wide bus and a clock of 400 kHz. Switching the bus width from 1 to 4 bit using the command HAL_SD_ConfigWideB...
My goal is to display text on the TFT LCD using stm32F756. The display I have is just the screen, no controller or gram. So I have configured the LTDC and was able to display a sample image which I stored in the flash. Now, the internal SRAM is not s...
Hello,I'm beginner in STM32 and would need help with HAL callback function usage.When I've started to use STM32s after PICs, one of the reasons why I was happy that the timer module encoder receiver function works really well, robust. I did used othe...
I want to initialize the STM32H573 ETH module using the STM32CubeMX code generator (see ioc file attached). It should run in MII mode using an external transceiver.I kept the configuration unchanged, however it always jumps to ErrorHandler, because H...
Hi, I use STM32CubeMX 6.10.0 and I have a STM32H7 CPU.The LPTIM is a frequency counter that can give an ISR when thecounter reached a specified value; after reaching this value it startsagain from zero (ARR mode), or it continues towards the max valu...
