Urgent: C5509 SDRAM access problem

Started by sirioseyes April 17, 2003

Hello,

I start this month to use SDRAM (64MBit) on spaces CE0 CE1, but I have some
problems.
I write a program that use DMA transfers from internal DARAM to SDRAM trough
the EMIF controller, my problem is that the system doesn't drive the addrs
A[9..12].I can use only the first 256 rows of the memory( A[1..8] works ).
I don't know where is the problem.
Can anyone help me?

Thank you in advance
Alessandro
