Re: [jornada] J7xx OE Config

Hi,

I know these kernel problems from my 56x.
I suggest that you start of with kernel 2.6 right away. In my opinion dealing
with kernel 2.4 is not very useful.
It would be great to have the 720 working in 2.6 with sysfs writes for
backlight and lcd control etc...

regards,
Alex
