Hello,

I use an NXP LPC2212 with an external Flash Spansion S29AL016D
connected by
Address bus and data bus

I can't communicate with Flash. I can't read or write over this
external
Flash.

Is it a problem of synchronisation?

Can you help me please?

Did you make sure to setup the BCFGx correctly to match the speed of the
flash chips?
