Dear Gentlemen,

 

i need some help with the D0 line pulldown, to configure the boot bus clock to half of the processor clock.

I used a 4,7K to pull down to ground, but the level at startup is floating from 2,5 to 1,5V.

On the data bus i have now conected only the MCF5307 and a sdram 48LC4M32B2.

 

Many thanks,

angelo
