Using DAC1_2 with SDRAM and HS USB PHY

Is this possible - even in a hacky way.the OPAMP2_VOUT (PE7 follower) output clashes with FMC_D4+the DAC1_OUT2 pin (PA5) clashes with USB HS ULPI CKSo is any configuration possible where DAC1_2, USB HS and SDRAM can work together?

STM32H747-DISCO (CM7 Used RTOS for Graphics, UART8) (CM4 Used for Tim1 PWM,SDMMI with FAT_M4.)

STM32H747-Disco, Cube IDE 1.10.1I've designed a UI using the method of MPV a few times in the past using one processor(CM7). Now, I'm using CM4 for sd card and PWM, I can't seem to get the model.cpp to recognize TIM1 handler (htmi1). I had made a s...

Using bootloader GO command with BOOT0 always asserted

I am using the I2C bootloader on STM32L431, in a system where another host CPU exists. I would like to minimize the number of host GPIO needed to manage entry to bootloader mode. (Currently the host is controlling the BOOT0 and RST# pins). I would...

Has the error in the function LL_ADC_SetChannelSingleDiff() been fixed?

The function LL_ADC_SetChannelSingleDiff() in stm32l4xx_ll_adc.h relies onshifting a 32 bit value 32 postions in order to clear a bit field.Shifting a word with >= the word size is undefined in the C standard and this generates erronous code when com...

STM32F7: Ethernet Wakeup from stop mode

Hi,I want to wakeup my STM32F746 + FreeRTOS + LwIP system with a magic packet. I started off with configuring the MAC to generate the interrupt when a Magic Packet is received, without entering the low power mode beforehand. This works perfectly fine...

Hello, I've tried to test sdcard with fatfs on STM32F429ZI on NUCLEO-F429ZI board. The same code was working in SD 1 bit mode((no DMA, no RTOS).when i configure SD 4 bit mode f_mount returns FR_NOT_READY.
