jerase all

Can't do that.  Only jerase the part where the rootfs is going.  You need to use regular erase for the part where your uImage is going, and for where you install u-boot (which you're not doing here, but you'd need erase not jerase if you were).

If you are using a recent u-boot from the buildroot, the best way to go is use the "katinstall" command to write uImage to the right place and erase that space properly first.
