Hi Luo
I think SD may be not quality. One can try
other quality SD from known vendors.
Another checkpoint - DDR settings, please recheck
Re: i.mx28 u-boot dram configuration for dram replacement.
and EMI_DDR_OPEN/EMI_DDR_OPEN_FB feedback loop length.
Best regards
chip
thank you chipexpert :
but our boards are the same sch, same components or ICs , included the dram chip.
so the dram should be same configuration.
Hi Luo
actually your boards not "same components or ICs" -
just because processors are different, isn' it ?
So modifying "DDR settings" may be actual.
Also I would suggest to change processor from good board
and place it on bad and vice versa and check behavior on both boards.
Best regards
chip
