Hi,

I am tryping to port lollipop 5.0.0. on my custom board with imx6dl processor. emmc is connected to sd4.

After porting the images on the board, the uboot is also not getting on. On the same boards Kitkat 4.4.2 is working.

Some where I read that for lollipop we need to add IVT header to uboot. How to do it.

Please guide.

Thanks and Regards,

VIVEK TOL

Hi VIVEK

IVT header is generated by uboot, for new board/ddr please run ddr test

i.MX6/7 DDR Stress Test Tool V2.52 | NXP Community

and modify  uboot *.cgf file, like uboot../mx6sabresd/mx6dl_4x_mt41j128.cfg

with new calibration settings obtained from ddr test.

Best regards

igor
