Hi Mike,

Please try setting both the Load Address and the Entry Point to the same value as you see as Entry point address by using 'readelf -h’ and try booting again.
In your case this would seem to be 0x80001100.

Please leave all dts/dtsi files unchanged (as they originally were) for now.

Best wishes,
Stanislav
