using boot stream but could use uboot.
I have an i.mx28 board based on the 28evk it has 2 sd cards slots, 1 for the booting (root fs and running kernel etc) and the other for application config file and sometimes kernel/driver updates.
What I'm seeking is a method to update/change a running kernel from the second sd card, how could i do this, is there a general method?
On a desktop I could replace/rename files in /boot and update /lib/modules whilst running (I think).
I've read a little about kexec as a possible solution.
Is there a better way to do this?
Any help or pointer links would be most appreciated.
