Dear all,

we are using the EP2C50672C6 FPGA and the EPCS16 as the boot device.

We connect

MSEL0 ----- GND

MSEL1 ----- GND

setting for AS

NCE ----- GND

N_STATUS --- weak pulled up

N_CONFIG --- weak pulled up

CONF_DONE --- weak pulled up

All connections based on Altera datasheets. However, device won't start reading from EPCS at power up.

Contacted a number of people for support and still no luck.
