I have two ADC channels that l am trying to configure to have their own ADC watchdog. Experimenting with the threshold values l can get the first watchdog to fire on each channel and it calls HAL_ADC_LevelOutOfWindowCallback() as needed. The second A...

Using the stm32h745I-disco board and there seems to be an issue using HAL_SPI_Transmit in a loop. I get the correct SPI data for the initial transmission, but after that the 16-bit value is all over the place. Only 0xFFFF remains the same over the lo...

I have full IwIP functionality inside a RTOS task due to this knowledge article: How to create project for STM32H7 with Ethernet and LwIP stack workingI am able to erase, write, and read the QSPI flash using a BSP_QSPI test function inside main. Thi...

l have initialized the Micron MT25TL01G QSPI chip with the BSP_QSPI_Init() function. I am able to read, write, and erase data to the QSPI using the underlying MT25TL01G functions beneath the BSP. Whenever l remove the BSP initialization l don't recei...

I'm confused regarding the importance of Quad-SPI for Ethernet communication. I see that pins PH2/PH3 were configured for QSPI without it being activated for either core. I tested leaving these pins in GPIO_Analog mode and still detected UDP broadcas...

Thank you. There may be a bug with the chip select. I switched from SPI Mode 3 to SPI Mode 0 and now l have a different error. The initial SPI transmission of 0xABCD is not recognized and there is a bit shift. This time the incorrect shifted value st...

No changing the delay didn't have an impact on the behavior of the SPI. Writing 0xABCD to the register exhibited the same incorrect value whether it had a 100 ms or 1000 ms delay over a loop. While changing the value to 0xFFFF remained correct over t...

I figured out that changing my BSP_QSPI configuration to QPI_Mode, and Dual_Transfer resolved the issue.

I am using the default indirect mode configured by the BSP, and don't think memory map mode is being used. I originally had the QSPI test function inside the main, but that caused MX_LWIP_Init() to not initiate inside the default task.The QSPI test f...

Debugging is being caught in the Invalidate D-Cache section of code. It only seems to happen when stepping through it. It is not hard faulting, and there are no errors being thrown when compiling. Both work fine independently but not together. I'm us...
