instruction cache problem wiht MCF5475

Hello,
 
I encounter some problems when enabling the instruction cache on my MCF5475 custom board.
The system hangs up just after writing in the CACR/ACR register... if the instruction cache is disabled, all is perfect.
The MCF54x5 simple project is used for this test.
On a Zoom devboard, I can not reproduce this phenomen. The only difference between my custom board and the Zoom one, is the memory which is a SDRAM and not a DDRAM...
Any idea ?
 
Thanks in advance
Nicolas
