@ssmith If you need a hard reset, you could connect a GPIO pin to Reset and pull that low. I have experienced the SD card issue too, which seems to require a pyhsical reset signal. But I dod not follow up that yet, whther it's a missimng software init of the SD card interface/driver, or a pysical reset signal missing.
