Updating Kernel only on mini210

I have a mini210 running Android and I am now able to build the Linux
Android kernel for it and also the Android OS on Ubuntu.

I am working on the Kernel to add in GPIO functionality and I want to be
able to just update the Kernel from SD card and not the Android OS.

Is this possible by just setting the kernel only in the ini file?

I don't want to have to flash the complete Android OS each time with the
kernel as it takes quite some time and no changes are required to the
Android part for now.

Thanks

Hello, I'm interested in this too... However, building kernel takes much
more time than flashing Android, it would be nice if it was possible to
load only kernel.

If you (or someone else) have found the solution, I would be very thankful
if you posted it here
