DDR register varification in U-boot for imx6q

[prathamrahate]

I have done calibration using DDR calibration tool on imx6q sabresd board. The results from calibration were different from that mentioned in DCD data in board/freescale/mx6sabresd/mx6q_4x_mt41j128.cfg. Why there is difference ??

Hi Pratham

it was created with older tool versions and works fine as

has sufficient calibration margins.

Thanks, Igor. I have used v2.52 tool, which is latest. That might be the difference.
