Our Customised design using IMX6ULL we are facing the issue in SD boot and eMMc boot because we are not using switch for BT_CFG2 to change Sd or eMMc boot.
We followed the NXP EVK boot configuration resistor setting same in our design.
Following are the Queries:
- Any difference in software ROM level between IMX6UL vs IMX6ULL processor?
- How IMX6UL design working fine without change in BT_CFG2 logic level but IMX6ULL doesn't work?
- Can be possible to change only Software code level(uboot) to make this board work SD/eMMC without hardware modification?
Please find the attached image which have marked the BT_CFG2
Thanks in advance,
