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.
