hello!
I have some trouble with dsk6711 emif.
the value in the EMIF registers is:
(this is according to my board condition)
*(unsigned int *)EMIF_GCR =0x30f8;
*(unsigned int *)EMIF_CE0 =0x30;
*(unsigned int *)EMIF_CE1 =0xffffff03;
*(unsigned int *)EMIF_CE2 =0xffffff23;
*(unsigned int *)EMIF_SDCTRL=0x07117000;
*(unsigned int *)EMIF_SDRP =0x61a;
*(unsigned int *)EMIF_SDEXT =0x54519;
the AREADY pin is pulled high on my board
When I access the CE2,I check CE2,AWE,ARE and AOE,and there is no
change on my oscilloscope(100MHz).I am confused,what is the matter
with my board.

hello shred_gao,
Sometimes it is very difficult to trigger a scope on a single event.
Try writing a simple endless loop that reads from [or writes to] the
first address of CE2, increments for 1M times and starts over.
Your scope should be able to pick up the signals.
