We have a new ST Vega design and are trying to make it boot. We have all the necessary clocks running correctly, and the SYSRSTO working as specified.

We are failing with getting both signals necessary read the boot flash.

If we select ISA bus mode, then ISAOE# is asserted, but not RMRTCCS#. If we select Local bus mode then FCS[1:0]# are both asserted, but not PRD#.

Any suggestions would be gratefully received.

This could be an invalid strap options on your design.

I advise you to check your hardware settings.
