I'm struggling with SD card handling. If anyone has a working config of
- STM32F429 or 427
- SD card
- Cube MX generated code
and able to make a oscilloscope recording, please send me the proper init sequence. 
For me it is
1) CMD0 (payload 0x00 0x00 0x00 0x00, no response required)
2) CMD8 (payload 0x00 0x00 0x01 0xaa),
3) no response in 200usec
4) CMD55 (payload 0x00 0x00 0x00 0x00)
but no response from the card, and no more messages sent to card.

I don't know if this is a card error, SD socket error, PCB/soldering error, or (CubeMX generated) code error.
