Sabre SD board fails Stress Tester

[sparkyee]

Hi,

    I have a Sabre SD board that passes calibration consistently. When I try to run

the graphical stress tester 2.4  the first address fails as follows:

address of failure 0x1000 0000

Data was: 0x10000008

But pattern should match address

Error: failed to run stress test!!

I am setting the start frequency to 350mhz and 525 for the end.

Any help would be appreciated. I am doing this in preparation for testing

my custom board of similar design to the Sabre SD.

Thanks!

Larry

Hi Larry

from log: "ddr_mr1=0x00000000 " -

MR1 should be set to meaningful value.

In script examples MR1=4 set in init script like:

setmem /32 0x021b001c = 0x00048031 // MMDC0_MDSCR, MR1 write, CS0

The MR1 value is upper 4 hex bits written to MMDCx_MDSCR

Also one can run ddr test without gui, it has mr1 in script text

Best regards
