[quote:ebcdc34e1b="nisse"]Jerry, I have a similar issue, could you share what HW problem you found?[/quote:ebcdc34e1b]
Hi nisse,
I am using FET (NXP BSN20) as a level translator to go from 5V processor to 3.3V SD card SPI bus. The pull-up resistor on output of translator clock signal was too weak to allow good rising edge clock and was causing problems. I revised pull-up value from 4.7K ohms to 1K ohms and all was well.
