SDRAM

Started by Arun Kumar November 1, 2006
Hi to all... I got n serious accident 15 days back. so could not
explain my problem last few days.. sorry...

I checked my setup today again.. the problem is still as it is... I
did many experiments that I am going to explain, please suggest me
some thing from these experiments

Step:-1
I powered on my Target Board.. and run the program for SDRAM test...

Step:2
I got the data mismatch at every 32 successive location as: -
Data Mismatch at location-1
Data Mismatch at location:-32
Data Mismatch at location:-64
Data Mismatch at location:-96
Data Mismatch at location:-128

Step: 3
I halted the running program and loaded the program again, I did not
Switched off the lsupply any where and run the program again.

This time: - My data is matched all the location up to 128th locations
but again I got the same statement of mismatch from the location
Data Mismatch at location:-160
Data Mismatch at location:-192
Data Mismatch at location:-224 onwards

Step:4
I halted the program without switching off the power and run the program again
This time I got the data matched again up to the location 224 and got
the problem again from the location
256 onwards successively on 32th locations.

Step: 5
I powered off the system and again run the program
I got the data mismatch at every 32 successive location as: -
Data Mismatch at location-1
Data Mismatch at location:-32
Data Mismatch at location:-64
Data Mismatch at location:-96
Data Mismatch at location:-128
and the Step:2,3,4,5 repeated

The same program is running fine on the Starter Kit of TI but not on
my target board.
I am not using the GEL file as when I configured the EMIF Locations it
is giving errors like, Trouble in writing CPU target memory at
0x01800004, 0x01800008,0x0180000C all SDRAM registers..

So I am running the program without GEL file.

Please Suggest some thing

Regards
Arun Kumar
