Voltage divider which produces reset for CY7C65211 is sized incorrectly, not producing 3.3V.
SD card is producing some valid data but is not actually coming up. Need to debug.
Should add zener diode to make sure that CY7C65211 reset is not high when VDD is 0V, so that the data usb only being plugged in doesn't break stuff. Also is it a risk of triggering the ESD diode?
SPI loopback resistor appears to be too high value. Can't reliably do SPI loopback at 1MHz on LPC1768. Need to look with a scope, and maybe switch out for like a 2.2k
