Hello, Is this actually documented somewhere for u-boot?
There is lots about writing to flash memories in the manual but MBR coexistence does not seem to be covered. u-boot is not written as a file but in a fixed location on the card where the i.MX6 looks for a bootloader. So you have on your SD card. | MBR - 1sector | 1 free sector (you get here with bs=1k seek=1) | u-boot | some space | start of first partition 0 your files here | You should make your first partition start far enough that u-boot, its environment (if any), etc can fit before it on the SD card.

The place for u-boot should be reserved when partitioning the card. > What can be the solution for this. It works as expected.
