It is one mandatory patch if you are in the case:
The chip you are using is imx6sx TO1.3 and newer, and use the kobs-ng to flash your image to the Nand memory chip. If you are using MFG, you also need rebuild the kobs-ng, and update the binary into your MFG tool. The patch have been integrated into the default release yocto_4.1.15, but if you are using the older version release before yocto_4.1.15, please make sure you have integrated the modification when you need to use kobs-ng to flash the image to Nand memory chip.

How to apply it to older version quickly:
Apply the patch and rebuild the kobs-ng in yocto_3.14_x environment:
Apply the patch and rebuild the kobs-ng in yocto_3.10_53 environment:
As one alternation method, you also can download the whole imx-kobs-5.4 package which yocto_4.1.15 is using to build.
