Flashing new android kernel

[Almindor]

We want to use the A13 WIFI board without the SD-card and we need a different kernel (1 patch to a driver + config change to enable the driver). I have successfuly compiled the kernel uImage but I have no idea how to flash it to the device NAND without making a whole new .img containing also the android framework (which we don't need to change).

How can I create a "kernel-only" image to flash and override on the /boot partition?

Thanks

I don't know how to do it but did you try to mount /dev/block/nanda (it is fat) on the running android system. There are some files there.

I've been told that the kernel resides in nandc and it's not a FS but just the image (e.g. can't be mounted, only DD-ed) the problem is I don't know it's start address and format (it's probably not a uImage but some packed up bImage)
