Resistance behind LDO3 to gnd 73 Ohms instead of ~1800 Ohms -> something else broken

epcq chip nCS is 0.4V (should be 3.3V?). K.O. |

|
epcq chip nCS, DCLK, DQ) is 0.4V, no activity. (should be 0V or 3.3V and show activity when accessed). K.O. |

firmware complains: FPGA is not in Remote Configuration mode. perhaps MSEL are bad? K.O. |
