I have build custom board and the shmoo result for 924MHz if I change EmcXm2DqsPadCtrl3 parameter are very different:
The board successfully pass sanity check with:
SDRAM.EmcXm2DqsPadCtrl3 = 0x5d75d700;
The board fail sanity check with:
SDRAM.EmcXm2DqsPadCtrl3 = 0x5d75d720;
I have checked on TRM TK1 and I found that this bit enable and disable:
I don’t understand very well the meaning of this parameter, someone could explain in which way this parameter can change the result?
The Jetson-tk1 reference board passes with both of them the sanity test.
