Hello All, I'm having a problem with an STM32G474 on a custom board. Overview of FaultFirst, weird behavior of the IWDG was observed. A hard fault was generated intentionally after 10 seconds of run time and no reset behavior was observed. Then, a wh...
Hi, I am working on a project on the STM32H730 that runs a high priority audio interrupt thread as well as a lower priority asynchronous loop for user interface processing and a 1ms SysTick interrupt for user interface processes that need some accura...
Hi guys,I am read the example "STM32Cube_FW_F1_V1.8.4\Projects\STM32F103RB-Nucleo\Examples\FLASH\FLASH_WriteProtection", and want to rewrite it on my board.my code is as follows: HAL_FLASH_Unlock(); HAL_FLASH_OB_Unlock(); HAL_FLASHEx_OBGetCo...
I have two codes, one only with the I2C4 communication working and the other code besides the I2C has the display but in this one the I2C communication does not work, what could be happening?With a logic analyzer I can see that in both codes the cloc...
Hello, everyone. I was trying to connect two prototypes in my computer: one containing a STM32L475 (connected through a ST-LINK V2) and the other using a STM32G474 (connected through a ST-LINK V3). The STM32CubeIDE warns about multiple ST-LINK connec...
Hello, everyone. I am developing a prototype using a STM32L475 and the NOR flash memory MT25QL512ABB. I am using the QuadSPI peripheral for the communication with these parameters:I used the QSPI_ReadWrite_IT example as a reference to fill these para...
I am designing a product with an STM32G474CET (LQFP48 package) and would like to use the ROM bootloader with I2C; looking at AN2606 section 48.1, I see that I must use I2C2, I2C3 or I2C4 if I want to use the ROM bootloader.This is fine, but according...
I'm going to rip my hair out... I mean There has been an issue with rapid disconnect and reconnect of the USB on our product, where the USB stops communicating. We enabled early suspend and when an erratic error (EERR) bit occurs during an early susp...
Hi guys,can someone please explain the internal trigger connections for the stm32f410 controllers to me?According to the referance manual (RM0401, see below) only TIM1 and TIM5 can be configured as slave timers with just ONE possible internal trigger...
Hi,I want to power a STM32Ux based board using USB-C port. I am required to use two numbers of a Type-A to USB-C type of cable and also it should support USB-C to USB-C type of cable in OR ring. Max load current of the board is less 1.5A. I am looki...
