So I think kexec will be possible on the Neo1973 you could have several systems parallel and when you need a stabil system for normal life you could choose. No idea if this will be interesting for normal user, but for shure for hackers like you ;) Cheers, rob PS: I love hacks like kexec and linux-vserver :))) - Thanks a lot, Alessandro ___ OpenMoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community ___ OpenMoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
Question about kernel level hacking
Hello! As I am mainly a low level programmer I will probably try to put my hands on the Neo at kernel level like customizing the linux kernel with patches or even try to program the Neo with my own kernel. I think that the openess of the platform will allow me that. Is it right? Is there a way to recover a mistake at this level (that is, the boot loader doesn't work any more)?
