update the beagle kernel with ftp when it's running

[Micka]

Hi,

I would like to know if someone has tried to update the kernel while the beagle is running ? Is it possible ?

Robert Nelson, when you compile the kernel, you put files in the bb-kernel/deploy folder. Can I copy those files to the beagle and untar during the boot ?

Micka,

kexec is enabled, try it ;)

Regards,

Well, I don't mind to reboot the beagle after. I was just wondering if it's possible to untar all the file while the beagle is running ? I'm worried about some file open by the kernel/linux !

Micka,

Kernel is in memory.. the biggest issue you might face is "loading" a
module after you've copied the new kernel/modules into the rootfs. As
depending on how you built it, there could be an abi diff.. (a reboot
would fix that issue to)..
