I am running just a basic read/write program, that can read and write, but looking at the debug messages, only one bus (instead of 4) is being used by the board to communicate to the SD card.
Also, while High Speed mode is "enabled" on the software, an oscilloscope shows that the actual reference clock for the bus is ~325 kHz.
Any advice?
