Hi Patrick,
If you are running your image embedded at some board, and have easy
access to the board, you can plug it to network and make u-boot
download kernel from your machine. So that deploy a new kernel becomes
simple as copy the new kernel to the tftp folder, and rebooting
target. This is also true for device-trees. And if you have NFS
support is true for all userspace too. :)
To be precise the statically linked kernel + dtb can be loaded by u-boot
over tftp (and nfs). The kernel modules are typically part of the rootfs
so they would be exported by nfs in our scenario.
I usually use symbolic links in my tftp export as well as which nfs
rootfs I export so I don't need to change the u-boot environment to boot
from something different. Like this it's just a matter of copying things
around on your PC and adjusting the symlinks.
Regards,
Robert
