I have designed the custom board based on imx6slevk. I am using SDcard for booting the images. I am unable to flash yocto 3.10.17 images to SDcard using the mfgtool 2.3.2. It is stopping at "jumping to OS" message. I checked with DDR stress test tool and it has passed the stress test so there is no issue with DDR. In my custom board am using micro SDcard for SD boot. My board is able to flash Linux LTIB version 3.0.35 images and also boots up but not yocto images. Is there anything i need to modify in the source file or using the micro SDcard in my custom board is the cause? Kindly help me.
