Re: MPC5200b jffs2 memcpy alignment problem

2012-07-02 Thread Stephan Gatzka
Hi! This problem has been discussed several times [1], [2], but wasn't resolved yet. The clean solution suggested was to implement a custom mapping driver [3]. Then I'll do that. It doesn't look terribly complicated. It would be helpful if someone can test the first version if it's

Hello! I'm curious if its possible to do the PTP hardware offset/adjustment calculation in a module internally to the kernel? That would allow the PPS interface to still be used to sync the system time, and not expose additional interfaces. Just my 2 cents on this issue. PTP is very often used
