I working to bring up new board.

I see problem booting from parallel nor.

When making the reset via the ICE the booting is started.

when booting after power up or using reset switch (connected to the input of supervisory) the booting sometime not started.

I drive The CPU HRESET pin from supervisory (which guaranty clean and long signal) to AND gate which inputs are the ICE_Hreset and POReset.

In addition AND gate which inputs are the ICE_TRST and POReset drive the CPU TRST pin.


Pls. advise
