ARM SoftwareLeveling fail

Hello,

In one of the Board we tried to do software levelling but failed to generate optimal seed values,

we are unable to Poke in Values to any DDR location,

I have attached the log file for CCS console output after running "DDR3_SlaveRatio_ByteWiseSearch_TI816x.out".

Please help on this issue asap.

Thanks,

Pramod

    Hello Pavel,

    Thanks for the reply,

    I am able to Run .Gel file and initialize the DDR Hardware, I Probed at DDR[0]_CLK[0] and DDR[0]_CLK[1] pins,

    Was able to make difference in P - P Voltage swing between ARM Booting Board and this Board on Clock pin of DDR,

    DDR Clock Level,

    ARM Booting Board - 200mVp-p,

    ARM Non Booting Board - 100mVp-p
