Hi all,
I'm still trying to use 6LowPan on my serial device.
But it does not work. I did successfully recompile my kernel and modules for my
Linux 64 bits architecture, ubuntu 11 ...
But maybe "Linux-Zigbee" things can't work with this architecture?
All seems verify fine except that when I set my lowpan interface UP, it gets UP
but the following kernel messages occur (See last paragraph).
Please hints ?
Here is my kernel version:
