I configured my custom imx6qd-board to have gpmi NAND. Working on uboot 2016.07+fslc
However, from the moment I try to read a written part, I get an read error -74
Erased parts are not a problem.
In u-boot 2015.04 (the bsp release version) it is working, also when booted to linux, it's working. So hardwarewise I don't think there's an issue. What can cause this? How can I debug this? Should I enable something more to make this work?
Looks something ECC-related, but that's dark magic to me...
